+2003-11-02  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (func_if): Strip all the trailing whitespace from the
+	condition, then don't expand it.  Fixed bug # 5798.
+
+	* expand.c (recursively_expand_for_file): If we're expanding a
+	variable with no file context, then use the variable's context.
+	Fixes bug # 6195.
+
+2003-10-21  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (log_working_directory): Add newlines to printf()s.
+
+	* README.cvs: Add a note to ignore warnings during autoreconf.
+
+	* maintMakefile (po_repo): Set a new URL for PO file updates.
+	(get-config/config.guess get-config/config.sub): Get these files
+	from the Savannah config project instead of ftp.gnu.org.
+
+2003-07-18  Paul D. Smith  <psmith@gnu.org>
+
+	* dir.c (directory_contents_hash_1, directory_contents_hash_1)
+	[WINDOWS32]: Initialize hash.
+
+2003-06-19  Earnie Boyd  <earnie@uses.sf.net>
+
+	* dir.c (read_dirstream): Provide a workaround for broken versions of
+	the MinGW dirent structure.
+
+2003-05-30  Earnie Boyd  <earnie@users.sf.net>
+
+	* w32/include/dirent.h: Add __MINGW32__ filter.
+
+2003-05-30  Earnie Boyd  <earnie@users.sf.net>
+
+	* make.h: Add global declaration of *make_host.
+	* main.c (print_usage): Remove local declaration of *make_host.
+	(print_version): Display "This program built for ..." after Copyright
+	notice.
+
+2003-05-30  Earnie Boyd  <earnie@users.sf.net>
+
+	* doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the
+	execution of "makeinfo --html make.texi".
+
+2003-04-30  Paul D. Smith  <psmith@gnu.org>
+
+	* build.template: Make some changes to maybe allow this script to
+	work on DOS/Windows/OS2 systems.  Suggested by Andreas Buening.
+
+	* README.OS2.template: New file for OS/2 support.  Original
+	contributed by Andreas Buening.
+	* configure.in: Invoke new pds_AC_DOS_PATHS macro to test for
+	DOS-style paths.
+
+2003-04-19  Paul D. Smith  <psmith@gnu.org>
+
+	Fix bug #1405: allow a target to match multiple pattern-specific
+	variables.
+
+	* rule.c (create_pattern_var, lookup_pattern_var): Move these to
+	variable.c, where they've always belonged.
+	* rule.h: Move the prototypes and struct pattern_var as well.
+	* variable.c (initialize_file_variables): Invoke
+	lookup_pattern_var() in a loop, until no more matches are found.
+	If a match is found, create a new variable set for the target's
+	pattern variables.  Then merge the contents of each matching
+	pattern variable set into the target's pattern variable set.
+	(lookup_pattern_var): Change this function to be usable
+	in a loop.  It takes a starting position: if NULL, start at the
+	beginning; if non-NULL, start with the pattern variable after that
+	position, and return the next matching pattern.
+	(create_pattern_var): Create a unique instance of
+	pattern-specific variables for every definition in the makefile.
+	Don't combine the same pattern together.  This allows us to
+	process the variable handling properly even when the same pattern
+	is used multiple times.
+	(parse_variable_definition): New function: break out the parsing
+	of a variable definition line from try_variable_definition.
+	(try_variable_definition): Call parse_variable_definition to
+	parse.
+	(print_variable_data_base): Print out pattern-specific variables.
+	* variable.h (struct variable): Remember when a variable is
+	conditional.  Also remember its flavor.
+	(struct pattern_var): Instead of keeping a variable set, we just
+	keep a single variable for each pattern.
+	* read.c (record_target_var): Each pattern variable contains only a
+	single variable, not a set, so create it properly.
+	* doc/make.texi (Pattern-specific): Document the new behavior.
+
+2003-04-17  Paul D. Smith  <psmith@gnu.org>
+
+	* dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by
+	Jean-Pierre Portier <portierjp2@free.fr>.  I don't understand the
+	file/directory naming rules for VMS so I can't tell whether this
+	is correct or not.
+
+2003-04-09  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in (HAVE_DOS_PATHS): Define this on systems that need
+	DOS-style pathnames: backslash separators and drive specifiers.
+
+2003-03-28  Paul D. Smith  <psmith@gnu.org>
+
+	* file.c (snap_deps): If .SECONDARY with no targets is given, set
+	the intermediate flag on all targets.  Fixes bug #2515.
+
+2003-03-24  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am:
+	Upgrade to autoconf 2.57 and automake 1.7.3.
+
+	* job.c: More OS/2 changes from Andreas Buening.
+
+	* file.c (print_file): Fix variable initialization.
+	Fixes bug #2892.
+
+	* remake.c (notice_finished_file):
+
+	* make.h (ENULLLOOP): Set errno = 0 before invoking the command;
+	some calls (like readdir()) return NULL in valid situations
+	without resetting errno.  Fixes bug #2846.
+
+2003-02-25  Paul D. Smith  <psmith@gnu.org>
+
+	Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>.
+
+	* job.c (_is_unixy_shell) [OS/2]: New function.
+	Set default shell to /bin/sh.
+	(reap_children): Close the job_rfd pipe here since we don't use a
+	SIGCHLD handler.
+	(set_child_handler_action_flags): define this to empty on OS/2.
+	(start_job_command): Close the jobserver pipe and use
+	child_execute_job() instead of fork/exec.
+	(child_execute_job): Rewrite to handle stdin/stdout FDs and spawn
+	rather than exec'ing, then reconfigure stdin/stdout.
+	(exec_command): Rewrite to use spawn instead of exec.  Return the
+	PID of the child.
+
+	* main.c (main) [OS/2]: Call initialize_main().  Handle argv[0] as
+	in DOS.  Handle the TEMP environment variable as in DOS.  Don't
+	use a SIGCHLD handler on OS/2.  Choose a shell as in DOS.  Don't
+	use -j in DOS mode.  Use child_execute_job() instead of
+	exec_command().
+
+	* function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use
+	spawn() instead.
+
+	* job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c.  Add
+	prototypes that return values.
+
+	* remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2.
+
+	* read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2.
+	* default.c (default_suffixes) [OS/2]: Set proper default suffixes
+	for OS/2.
+	* vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like
+	DOS paths.
+
+2003-02-24  Paul D. Smith  <psmith@gnu.org>
+
+	* default.c [VMS]: New default rules for .cxx -> .obj compiles.
+	* job.c (child_execute_job) [VMS]: New code for handling spawn().
+	(child_execute_job) [VMS]: Handle error status properly.
+	Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>.
+
+	* function.c (func_shell): Use EINTRLOOP() while reading from the
+	subshell pipe (Fixes bug #2502).
+	* job.c (free_child): Use EINTRLOOP() while writing tokens to the
+	jobserver pipe.
+	* main.c (main): Ditto.
+
+2003-01-30  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (eval): eval() was not fully reentrant, because the
+	collapsed buffer was static.  Change it to be an automatic
+	variable so that eval() can be invoked recursively.
+	Fixes bug # 2238.
+	(eval): Apply patch # 1022: fix memory reference error on long
+	target-specific variable lines.
+	Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
+
+	* function.c (check_numeric): Combine the is_numeric() function
+	into this function, since it's only called from one place.
+	Constify this function.  Have it print the incorrect string in the
+	error message.  Fixes bug #2407.
+	(strip_whitespace): Constify.
+	(func_if): Constify.
+	* expand.c (expand_argument): Constify.
+
+2003-01-29  Paul D. Smith  <psmith@gnu.org>
+
+	Fix bug # 2169, also reported by other people on various systems.
+
+	* make.h: Some systems, such as Solaris and PTX, do not fully
+	implement POSIX-compliant SA_RESTART functionality; important
+	system calls like stat() and readdir() can still fail with EINTR
+	even if SA_RESTART has been set on the signal handler.  So,
+	introduce macros EINTRLOOP() and ENULLLOOP() which can loop on
+	EINTR for system calls which return -1 or 0 (NULL), respectively,
+	on error.
+	Also, remove the old atomic_stat()/atomic_readdir() and
+	HAVE_BROKEN_RESTART handling.
+
+	* configure.in: Remove setting of HAVE_BROKEN_RESTART.
+
+	* arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat().
+	* remake.c (touch_file): Ditto.
+
+	* commands.c (delete_target): Use EINTRLOOP() to wrap stat().
+	* read.c (construct_include_path): Ditto.
+	* remake.c (name_mtime): Ditto.
+	* vpath.c (selective_vpath_search): Ditto.
+	* dir.c (find_directory): Ditto.
+	(local_stat): Ditto.
+	(find_directory): Use ENULLLOOP() to wrap opendir().
+	(dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir().
+
+	* misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and
+	atomic_readdir() handling.
+
+2003-01-22  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (func_call): Fix Bug #1744.  If we're inside a
+	recursive invocation of $(call ...), mask any of the outer
+	invocation's arguments that aren't used by this one, so that this
+	invocation doesn't "inherit" them accidentally.
+
+2002-12-05  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (subst_expand): Valery Khamenia reported a
+	pathological performance hit when doing substitutions on very
+	large values with lots of words: turns out we were invoking
+	strlen() a ridiculous number of times.  Instead of having each
+	call to sindex() call strlen() again, keep track of how much of
+	the text we've seen and pass the length to sindex().
+
+2002-11-19  Paul D. Smith  <psmith@gnu.org>
+
+	* README.cvs, configure.in: Upgrade to require autoconf 2.56.
+
+
+2002-11-16  Paul D. Smith  <psmith@gnu.org>
+
+	* NMakefile.template (OBJS): Add hash.c object file.
+	* SMakefile.template (srcs): Ditto.
+	* Makefile.ami (objs): Ditto.
+	* build_w32.bat: Ditto.
+
+	* Makefile.DOS.template: Remove extra dependencies.
+
+2002-10-25  Paul D. Smith  <psmith@gnu.org>
+
+	* expand.c (install_variable_buffer): New function.  Install a new
+	variable_buffer context and return the previous one.
+	(restore_variable_buffer): New function.  Free the current
+	variable_buffer context and put a previously saved one back.
+	* variable.h: Prototypes for {install,restore}_variable_buffer.
+	* function.c (func_eval): Push a new variable_buffer context
+	before we eval, then restore the old one when we're done.
+	Fixes Bug #1517.
+
+	* read.c (install_conditionals): New function.  Install a new
+	conditional context and return the previous one.
+	(restore_conditionals): New function.  Free the current
+	conditional context and put a previously saved one back.
+	(eval): Use the {install,restore}_conditionals for "include"
+	handling.
+	(eval_buffer): Use {install,restore}_conditionals to preserve the
+	present conditional state before we evaluate the buffer.
+	Fixes Bug #1516.
+
+	* doc/make.texi (Quick Reference): Add references to $(eval ...)
+	and $(value ...).
+	(Recursion): Add a variable index entry for CURDIR.
+
+	* README.cvs: Update to appropriate versions.
+	* Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I
+	don't need to copy loadavg.c: automake is smart enough to create
+	it for me.  Still have a bug in automake related to ansi2knr tho.
+
+2002-10-14  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (notice_finished_file): Only touch targets if they have
+	at least one command (as per POSIX).  Resolve Bug #1418.
+
+	* *.c: Convert to using ANSI C-style function definitions.
+	* Makefile.am: Enable the ansi2knr feature of automake.
+	* configure.in: ditto.
+
+2002-10-13  Paul D. Smith  <psmith@gnu.org>
+
+	* commands.c (set_file_variables): Bug #1379: Don't use alloca()
+	for automatic variable values like $^, etc.  In the case of very
+	large lists of prerequisites this causes problems.  Instead reuse
+	a static buffer (resizeable) for each variable.
+
+	* read.c (eval): Fix Bug #1391: allow "export" keyword in
+	target-specific variable definitions.  Check for it and set an
+	"exported" flag.
+	(record_target_var): Set the export field to v_export if the
+	"exported" flag is set.
+	* doc/make.texi (Target-specific): Document the ability to use
+	"export".
+
+	* doc/make.texi: Change the name of the section on automatic
+	variables from "Automatic" to "Automatic Variables".  Added text
+	clarifying the scope of automatic variables.
+
+2002-10-04  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (eval): Allow SysV $$@ variables to use {} braces as well
+	as () braces.
+	(record_files): Ditto.
+
+	* expand.c (variable_expand_string): In $(A:x=y) expansion limit
+	the search for the '=' to only within the enclosing parens.
+
+2002-10-03  Paul D. Smith  <psmith@gnu.org>
+
+	Version 3.80 released.
+
+	* dir.c: Change hash functions to use K&R function definition style.
+	* function.c: Ditto.
+	* read.c: Ditto.
+	* variable.c: Ditto.
+
+	Update to automake 1.7.
+
+	* Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7.
+	(pdf): Remove this target as automake now provides one.
+
+	* configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS.
+
+2002-09-30  Martin P.J. Zinser  <zinser@decus.de>
+
+	* makefile.com: Updates for GNU make 3.80.
+	* makefile.vms: Ditto.
+
+2002-09-23  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (enum make_word_type): Remove w_comment.
+	(get_next_mword): Don't treat comment characters as special; where
+	this function is used we will never see a comment (it's stripped
+	before we get here) and treating comments specially means that
+	targets like "foo\#bar" aren't handled properly.
+
+2002-09-18  Paul D. Smith  <psmith@gnu.org>
+
+	* doc/make.texi (Bugs): Update with some info on Savannah, etc.
+
+	* read.c (eval): Expansion of arguments to export/unexport was
+	ignoring all arguments after the first one.  Change the algorithm
+	to expand the whole line once, then parse the results.
+
+2002-09-17  Paul D. Smith  <psmith@gnu.org>
+
+	Fix Bug #940 (plus another bug I found while looking at this):
+
+	* read.c (record_target_var): enter_file() will add a new entry if
+	it's a double-colon target: we don't want to do that in this
+	situation.  Invoke lookup_file() and only enter_file() if it does
+	not already exist.  If the file we get back is a double-colon then
+	add this variable to the "root" double-colon target.
+
+	* variable.c (initialize_file_variables): If this file is a
+	double-colon target but is not the "root" target, then initialize
+	the root and make the root's variable list the parent of our
+	variable list.
+
+2002-09-13  Paul D. Smith  <psmith@gnu.org>
+
+	* doc/make.texi (MAKE Variable): Add some indexing for "+".
+
+	* hash.c (round_up_2): Get rid of a warning.
+
+2002-09-12  Paul D. Smith  <psmith@gnu.org>
+
+	* Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake
+	so it doesn't complain about getloadavg.c.
+
+	* commands.c (set_file_variables): Make sure we always alloca() at
+	least 1 character for the value of $? (for '\0').
+
+2002-09-11  Paul D. Smith  <psmith@gnu.org>
+
+	* hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix
+	macro to use RESULT instead of the incorrect _RESULT_.
+
+	* make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat()
+	and atomic_readdir().  We need to #include dirent.h to get this to
+	work.
+	* misc.c (atomic_readdir): Fix typos.
+
+2002-09-10  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (eval): Expand variable lists given to export and
+	unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works.
+	(conditional_line): Ditto for "ifdef".  Fixes bug #103.
+
+	* doc/make.texi (Variables/Recursion): Document this.
+	(Conditional Syntax): And here.
+
+2002-09-09  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Check for memmove().
+
+2002-09-07  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems;
+	Michael Sterrett <msterret@coat.com> reports that while it has
+	SA_RESTART, it does not work properly.
+
+	* misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function
+	that invokes stat() and loops to do it again if it returns EINTR.
+	(atomic_readdir): Ditto, with readdir().
+
+	* make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat()
+	and readdir() to atomic_stat() and atomic_readdir().
+
+2002-09-04  Paul D. Smith  <psmith@gnu.org>
+
+	* implicit.c (pattern_search): Daniel <barkalow@reputation.com>
+	reports that GNU make sometimes doesn't recognize that targets can
+	be made, when directories can be created as prerequisites.  He
+	reports that changing the order of predicates in the DEP->changed
+	flag test so that lookup_file() is always performed, solves this
+	problem.
+
+2002-08-08  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Require a newer version of gettext.
+
+	* misc.c (perror_with_name): Translate the format string (for
+	right-to-left language support).
+	(pfatal_with_name): Ditto.
+
+	* main.c: Create a static array of strings to store the usage
+	text.  This is done to facilitate translations.
+	(struct command_switch): Remove argdesc and description fields.
+	(switches): Remove values for obsolete fields.
+	(print_usage): Print each element of the usage array.
+
+	* hash.c: Change function definitions to be K&R style.
+
+2002-08-02  Paul D. Smith  <psmith@gnu.org>
+
+	* NEWS: Remove the mention of .TARGETS; we aren't going to publish
+	this one because it's too hard to get right.  We'll look at it for
+	a future release.
+	* main.c (main): Don't create the .TARGETS variable.
+	* variable.c (handle_special_var): Don't handle .TARGETS.
+
+2002-08-01  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (switches): Add a new option, -B (--always-make).  If
+	specified, make will rebuild all targets that it encounters even
+	if they don't appear to be out of date.
+	(always_make_flag): New flag.
+	* make.h: Extern always_make_flag.
+	* remake.c (update_file_1): Check always_make_flag; if it's set we
+	will always rebuild any target we can, even if none of its
+	prerequisites are newer.
+	* NEWS: Mention it.
+
+	* doc/make.texi (Shell Function): Make it clear that make
+	variables marked as "export" are not passed to instances of the
+	shell function.
+
+	Add new introspection variable .VARIABLES and .TARGETS.
+
+	* variable.c (handle_special_var): New function.  If the variable
+	reference passed in is "special" (.VARIABLES or .TARGETS),
+	calculate the new value if necessary.  .VARIABLES is handled here:
+	walk through the hash of defined variables and construct a value
+	which is a list of the names.  .TARGETS is handled by
+	build_target_list().
+	(lookup_variable): Invoke handle_special_var().
+	* file.c (build_target_list): Walk through the hask of known files
+	and construct a list of the names of all the ones marked as
+	targets.
+	* main.c (main): Initialize them to empty (and as simple variables).
+	* doc/make.texi (Special Variables): Document them.
+	* NEWS: Mention them.
+
+	* variable.h (struct variable): Add a new flag "exportable" which
+	is true if the variable name is valid for export.
+	* variable.c (define_variable_in_set): Set "exportable" when a new
+	variable is defined.
+	(target_environment): Use the "exportable" flag	instead of
+	re-checking the name here... an efficiency improvement.
+
+2002-07-31  Paul D. Smith  <psmith@gnu.org>
+
+	* config.h-vms.template: Updates to build on VMS.  Thanks to
+	Brian_Benning@aksteel.com for helping verify the build.
+	* makefile.com: Build the new hash.c file.

+
+	Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the
+	prerequisite list.  A real SysV make will expand the entire
+	prerequisites list _twice_: we don't do that as it's a big
+	backward-compatibility problem.  We only replace those specific
+	variables.
+
+	* read.c (record_files): Replace any $@, $(@D), and $(@F) variable
+	references left in the list of prerequisites.  Check for .POSIX as
+	we record targets, so we can disable non-POSIX behavior while
+	reading makefiles as well as running them.
+	(eval): Check the prerequisite list to see if we have anything
+	that looks like a SysV prerequisite variable reference.
+
+2002-07-09  Paul D. Smith  <psmith@gnu.org>
+
+	* doc/make.texi (Prerequisite Types): Add a new section describing
+	order-only prerequisites.
+
+	* read.c (uniquize_deps): If we have the same file as both a
+	normal and order-only prereq, get rid of the order-only prereq,
+	since the normal one supersedes it.
+
+2002-07-08  Paul D. Smith  <psmith@gnu.org>
+
+	* AUTHORS: Added Greg McGary to the AUTHORS file.
+	* NEWS: Blurbed order-only prerequisites.
+	* file.c (print_file): Show order-only deps properly when printing
+	the database.
+
+	* maintMakefile: Add "update" targets for wget'ing the latest
+	versions of various external files.  Taken from Makefile.maint in
+	autoconf, etc.
+
+	* dosbuild.bat: Somehow we got _double_ ^M's.  Remove them.
+	Reported by Eli Zaretskii <eliz@is.elta.co.il>.
+
+2002-07-07  Paul D. Smith  <psmith@gnu.org>
+
+	* po/*.po: Remove.  We'll use wget to retrieve them at release
+	time.
+
+	* variable.c (do_variable_definition) [W32]: On W32 using cmd
+	rather than a shell you get an exception.  Make sure we look up
+	the variable.  Patch provided by Eli Zaretskii <eliz@is.elta.co.il>.
+
+	* remake.c (notice_finished_file): Fix handling of -t flag.
+	Patch provided by Henning Makholm <henning@makholm.net>.
+
+	* implicit.c (pattern_search): Some systems apparently run short
+	of stack space, and using alloca() in this function caused an
+	overrun.  I modified it to use xmalloc() on the two variables
+	which seemed like they might get large.  Fixes Bug #476.
+
+	* main.c (print_version): Update copyright notice to conform with
+	GNU standards.
+	(print_usage): Update help output.
+
+	* function.c (func_eval): Create a new make function, $(eval
+	...).  Expand the arguments, put them into a buffer, then invoke
+	eval_buffer() on the resulting string.
+	(func_quote): Create a new function, $(quote VARNAME).  Inserts
+	the value of the variable VARNAME without expanding it any
+	further.
+
+	* read.c (struct ebuffer): Change the linebuffer structure to an
+	"eval buffer", which can be either a file or a buffer.
+	(eval_makefile): Move the code in the old read_makefile() which
+	located a makefile into here: create a struct ebuffer with that
+	information.  Have it invoke the new function eval() with that
+	ebuffer.
+	(eval_buffer): Create a new function that creates a struct ebuffer
+	that holds a string buffer instead of a file.  Have it invoke
+	eval() with that ebuffer.
+	(eval): New function that contains the guts of the old
+	read_makefile() function: this function parses makefiles.  Obtains
+	data to parse from the provided ebuffer.  Some modifications to
+	make the flow of the function cleaner and clearer.  Still could
+	use some work here...
+	(do_define): Takes a struct ebuffer instead of a FILE*.  Read the
+	contents of the define/endef variable from the ebuffer.
+	(readstring): Read the next line from a string-style ebuffer.
+	(readline): Read the next line from an ebuffer.  If it's a string
+	ebuffer, invoke readstring().  If it's a FILE* ebuffer, read it
+	from the file.
+
+	* dep.h (eval_buffer): Prototype eval_buffer();
+
+	* variable.c (do_variable_definition): Make sure that all
+	non-target-specific variables are registered in the global set.
+	If we're invoked from an $(eval ...) we might be inside a $(call
+	...) or other function which has pushed a variable scope; we still
+	want to define our variables from evaluated makefile code in the
+	global scope.
+
+2002-07-03  Greg McGary  <greg@mcgary.org>
+
+	* dep.h (struct dep) [ignore_mtime]: New member.

+	* main.c (main, handle_non_switch_argument): Likewise.
+	* rule.c (convert_suffix_rule): Likewise.
+	* read.c (read_all_makefiles, read_makefile, multi_glob): Likewise.
+	(read_makefile): Parse '|' in prerequisite list.
+        (uniquize_deps): Consider ignore_mtime when comparing deps.
+	* remake.c (update_file_1, check_dep): Don't force remake for
+	dependencies that have d->ignore_mtime.
+	* commands.c (FILE_LIST_SEPARATOR): New constant.
+        (set_file_variables): Don't include a
+	prerequisite in $+, $^ or $? if d->ignore_mtime.
+        Define $|.
+
+2002-06-18  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo: Updates for next revision.  New date/rev/etc.
+	Recreate all Info menus.  Change license on the manual to the GNU
+	Free Documentation License.  A number of typos.
+	(Variables Simplify): Don't use "-" before it's defined.
+	(Automatic Prerequisites): Rewrite the target example to work
+	properly if the compile fails.  Remove incorrect comments about
+	how "set -e" behaves.
+	(Text Functions): Move the "word", "wordlist", "words", and
+	"firstword" functions here, from "File Name Functions".
+	* make-stds.texi: Update from latest GNU version.
+	* fdl.texi: (created) Import the latest GNU version.
+
+2002-06-06  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (do_variable_definition): New function: extract the
+	part of try_variable_definition() that actually sets the value
+	into a separate function.
+	(try_variable_definition): Call do_variable_definition() after
+	parsing the variable definition string.
+	(define_variable_in_set): Make the name argument const.
+
+	* variable.h (enum variable_flavor): Make public.
+	(do_variable_definition): Create prototype.
+
+	* read.c (read_all_makefiles): Create a new built-in variable,
+	MAKEFILE_LIST.
+	(read_makefile): Add each makefile read in to this variable value.
+
+2002-05-18  Eli Zaretskii  <eliz@is.elta.co.il>

+
+2002-05-09  Paul D. Smith  <psmith@gnu.org>
+
+	* file.c (file_timestamp_now): Use K&R function declaration.
+
+	* getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils
+	getloadavg.c.  Autoconf thinks QNX is SVR4-like, but it isn't, so
+	#undef it.  Remove predefined setup of NLIST_STRUCT.  Decide
+	whether to include nlist.h based on HAVE_NLIST_H.  Change obsolete
+	NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME.
+	* configure.in (NLIST_STRUCT): Define this if we have nlist.h and
+	nlist.n_name is a pointer rather than an array.
+
+	* acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest
+	version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS.
+	* configure.in: Use it instead of the old version.
+
+	* main.c (main): Prefer setvbuf() to setlinebuf().
+
+2002-05-08  Paul D. Smith  <psmith@gnu.org>
+
+	* Makefile.am (make_LDADD): Add GETLOADAVG_LIBS.
+	(loadavg_LDADD): Ditto.
+
+2002-04-29  Paul D. Smith  <psmith@gnu.org>
+
+	* expand.c (recursively_expand_for_file): Rename
+	recursively_expand() to recursively_expand_for_file() and provide
+	an extra argument, struct file.  If the argument is provided, set
+	the variable scope to that of the file before expanding.
+	* variable.h (recursively_expand): Make this a macro that invokes
+	recursively_expand_for_file() with a NULL file pointer.
+	* variable.c (target_environment): Call the renamed function and
+	provide the current file context.
+	Fixes Debian bug #144306.
+
+2002-04-28  Paul D. Smith  <psmith@gnu.org>
+
+	Allow $(call ...) user-defined variables to be self-referencing
+	without throwing an error.  Allows implementation of transitive
+	closures, among other possibly useful things.
+	Requested by: Philip Guenther <guenther@sendmail.com>
+
+	* variable.h (struct variable): Add a new field: exp_count, and
+	new macros to hold its size and maximum value.
+	(warn_undefined): Make this a macro.
+	* variable.c (define_variable_in_set): Initialize it.
+	* expand.c (recursively_expand): If we detect recursive expansion
+	of a variable, check the exp_count field.  If it's greater than 0
+	allow the recursion and decrement the count.
+	(warn_undefined): Remove this (now a macro in variable.h).
+	* function.c (func_call): Before we expand the user-defined
+	function, modify its exp_count field to contain the maximum
+	number of recursive calls we'll allow.  After the call, reset it
+	to 0.
+
+2002-04-21  Paul D. Smith  <psmith@gnu.org>
+
+	Modified to use latest autoconf (2.53), automake (1.6.1), and
+	gettext (0.11.1).  We're using gettext's new "external" support,
+	to avoid including libintl source with GNU make.
+
+	* README.cvs: New file.  Explain how to build GNU make from CVS.
+
+	* configure.in: Modify checking for the system glob library.
+	Use AC_EGREP_CPP instead of AC_TRY_CPP.  Remove the setting of
+	GLOBDIR (we will always put "glob" in SUBDIRS, so automake
+	etc. will manage it correctly).  Set an automake conditional
+	USE_LOCAL_GLOB to decide whether to compile the glob library.
+
+	* getloadavg.c (main): Include make.h in the "TEST" program to
+	avoid warnings.
+
+	* Makefile.am: Remove special rules for loadavg.  Replace them
+	with Automake capabilities for building extra programs.
+
+	* signame.c: This file does nothing if the system provide
+	strsignal().  If not, it implements strsignal().  If the system
+	doesn't define sys_siglist, then we make our own; otherwise we use
+	the system version.
+	* signame.h: Removed.
+
+	* main.c (main): No need to invoke signame_init().  Update copyright.
+
+	* ABOUT-NLS: Removed.
+	* gettext.c: Removed.
+	* gettext.h: Get a simplified copy from the gettext package.
+	* po/*: Created.
+	* i18n/*.po: Moved to po/.
+	* i18n/: Removed.
+
+	* config/*: Created.  Contains package configuration helper files.
+	* config.guess, config.sub: Moved to config directory.
+
+	* configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile.
+	Rework to use new-style autoconf features.  Use the "external"
+	mode for gettext.  Make the build.sh config file conditional on
+	whether build.sh.in exists, to avoid autoconf errors.
+	* acinclude.m4: Removed almost all macros as being obsolete.
+	Rewrote remaining macros to use AC_DEFINE.
+	* acconfig.h: Removed.
+
+	* Makefile.am (EXTRA_DIST): Add config/config.rpath.  Use a
+	conditional to handle customs support.  Remove special handling
+	for i18n features.
+
+2002-04-20  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (func_call): Don't mark the argument variables $1,
+	etc. as recursive.  They've already been fully expanded so
+	there's no need to do it again, and doing so strips escaped $'s.
+	Reported by Sebastian Glita <glseba@yahoo.com>.
+
+	* remake.c (notice_finished_file): Walk through double-colon
+	entries via the prev field, not the next field!
+	Reported by Greg McGary <greg@mcgary.org>.
+
+	* main.c (main): If the user specifies -q and asks for a specific
+	target which is a makefile, we got an assert.  In that case it
+	turns out we should continue normally instead.
+
+	* i18n/de.po, i18n/fr.po: Installed an updated translation.

+	the way in which we manage the file descriptor/signal handler race
+	trap to be more efficient.
+
+2001-05-06  Paul Eggert  <eggert@twinsun.com>
+
+	Restart almost all system calls that are interrupted, instead
+	of worrying about EINTR.  The lone exception is the read() for
+	job tokens.
+
+	* configure.in (HAVE_SA_RESTART): New macro.
+	(MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART.
+	* main.c (main): Use SA_RESTART instead of the old,
+	nonstandard SA_INTERRUPT.
+
+	* configure.in (AC_CHECK_FUNCS): Add bsd_signal.
+	* main.c (bsd_signal): New function or macro,
+	if the implementation doesn't supply it.
+	(The bsd_signal function will be in POSIX 1003.1-200x.)
+	(HANDLESIG): Remove.
+	(main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG.
+
+	* make.h (EINTR_SET): Remove.
+	(SA_RESTART): New macro.
+
+	* arscan.c (ar_member_touch): Don't worry about EINTR.
+	* function.c (func_shell): Likewise.
+	* job.c (reap_children, free_child, new_job): Likewise.
+	* main.c (main): Likewise.
+	* remake.c (touch_file, name_mtime): Likewise.
+
+	* arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal;
+	if fstat failed with errno!=EINTR, the error was ignored.
+
+	* job.c (set_child_handler_action_flags): New function.
+	(new_job): Use it to temporarily clear the SIGCHLD action flags
+	while reading the token.
+
+2001-05-02  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (start_job_command): Don't add define/endef per-line flags
+	to the top-level flags setting.
+
+2001-04-03  Paul D. Smith  <psmith@gnu.org>
+
+	* arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low
+	bit on error, so check for odd return values, not non-0 return
+	values.
+	(VMS_get_member_info): Calculate the timezone differences correctly.
+	Reported by John Fowler <jfowler@nyx.net>.
+
+
+2001-03-14  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (lookup_variable) [VMS]: Null-terminate the variable
+	value before invoking define_variable().
+	Reported by John Fowler <jfowler@nyx.net>.
+
+2001-02-07  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (record_target_var): If we reset the variable due to a
+	command-line variable setting overriding it, turn off the "append"
+	flag.
+
+2001-01-17  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (lookup_variable) [VMS]: When getting values from the
+	environment, allocate enough space for the _value_ plus escapes,
+	not enough space for the name plus escapes :-/.
+	Reported by John Fowler <jfowler@nyx.net>.
+
+	* remake.c (f_mtime): Removed the "***" prefix from the mod time
+	warnings that make generates, so it doesn't look like an error.
+	Reported by Karl Berry <karl@gnu.org>.
+
+
+	Fix for PR/2020:  Rework appended target-specific variables.  I'm
+	fairly confident this algorithm is finally correct.
+
+	* expand.c (allocated_variable_append): Rewrite.  Instead of
+	expanding each appended variable then adding all the expanded
+	strings together, we append all the unexpanded values going up
+	through the variable set contexts, then expand the final result.
+	This behaves just like non-target-specific appended variable
+	values, while the old way didn't in various corner cases.
+	(variable_append): New function: recursively append the unexpanded
+	value of a variable, walking from the outermost variable scope to
+	the innermost.
+	* variable.c (lookup_variable): Remove the code that looked up the
+	variable set list if the found variable was "append".  We don't
+	need this anymore.
+	(lookup_variable_in_set): Make this non-static so we can use it
+	elsewhere.
+	(try_variable_definition): Use lookup_variable_in_set() rather
+	than faking out current_variable_set_list by hand (cleanup).
+	* variable.h: Add a prototype for the now non-static
+	lookup_variable_in_set().
+
+2000-11-17  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the
+	WINDOWS32 port to assume timestamps can be up to 3 seconds away
+	before throwing a fit.
+
+2000-11-17  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (readline): CRLF calculations had a hole, if you hit the
+	buffer grow scenario just right.  Reworked the algorithm to avoid
+	the need for len or lastlen at all.  Problem description with
+	sample code chages provided by Chris Faylor <cgf@redhat.com>.
+
+2000-10-24  Paul D. Smith  <psmith@gnu.org>

+2000-10-05  Paul D. Smith  <psmith@gnu.org>
+
+	* acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro
+	AM_LC_MESSAGES; it doesn't seem to do anything anyway??
+
+	* i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation.
+
+2000-09-22  Paul D. Smith  <psmith@gnu.org>
+
+	* gettext.c: Don't #define _GETTEXT_H here; we only include some
+	parts of the real gettext.h here, and we expect to really include
+	the real gettext.h later.  If we keep this #define, it's ignored.
+
+2000-09-21  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (log_working_directory): Rework the text to use complete
+	sentences, to make life simpler for the translators.
+
+2000-08-29  Paul D. Smith  <psmith@gnu.org>
+
+	* file.c (remove_intermediates): Print a debug message before we
+	remove intermediate files, so the user (if she uses -d) knows
+	what's going on.
+
+2000-08-21  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (try_variable_definition): Change how we handle
+	target-specific append variable defns: instead of just setting the
+	value, expand it as an append _but_ only within the current
+	target's context.  Otherwise we lose all but the last value if the
+	variable is appended more than once within the current target
+	context.  Fixes PR/1831.
+
+2000-08-16  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (func_shell): Nul-terminate the buffer before
+	printing an exec error message (just in case it's not!).
+	Fixes PR/1860, reported by Joey Hess <joey@valinux.com>.
+
+2000-07-25  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (construct_command_argv_internal): Add "~" to the list of
+	sh_chars[] which disallow optimizing out the shell call.
+
+2000-07-23  Paul Eggert  <eggert@twinsun.com>
+
+	* NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which
+	supersedes --disable-nsec-timestamps.
+	* make.texinfo: Consistently use "time stamp" instead of "timestamp".
+	* README: Remove --disable-nsec-timestamps.
+
+	* filedef.h (struct file.low_resolution_time): New member.
+	* file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME.
+	* remake.c (update_file_1):
+	Avoid spurious rebuilds due to low resolution time stamps,
+	generalizing the earlier code that applied only to archive members.
+	(f_mtime): Archive members always have low resolution time stamps.
+
+	* configure.in: Remove --disable-nsec-timestamps, as this has
+	been superseded by .LOW_RESOLUTION_TIME.
+
+2000-07-23  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.in (enable_nsec_timestamps): Renamed from
+	make_cv_nsec_timestamps, since enable/disable options
+	shouldn't be cached.
+
+2000-07-23  Bruno Haible  <haible@clisp.cons.org>
+       and  Paul Eggert  <eggert@twinsun.com>
+
+	* file.c (file_timestamp_now):
+	Use preprocessor-time check for FILE_TIMESTAMP_HI_RES
+	so that clock_gettime is not linked unless needed.
+
+	* filedef.h (FILE_TIMESTAMP_HI_RES):
+	Remove definition; "configure" now does this.
+
+	* configure.in (jm_AC_TYPE_UINTMAX_T): Move up,
+	to before high resolution file timestamp check,
+	since that check now uses uintmax_t.
+	(FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use
+	high resolution file timestamps.
+	(HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES,
+	so that we don't link in clock_gettime unnecessarily.
+
+2000-07-17  Paul D. Smith  <psmith@gnu.org>
+
+	* i18n/ja.po: New version of the translation file.
+
+2000-07-07  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (f_mtime): If NO_FLOAT is defined, don't bother with
+	the offset calculation.
+	(name_mtime): Replace EINTR test with EINTR_SET macro.
+
+2000-07-07  Paul Eggert  <eggert@twinsun.com>
+
+	Fix for PR/1811:
+
+	* remake.c (update_file_1):
+	Avoid spurious rebuilds of archive members due to their
+	timestamp resolution being only one second.
+	(f_mtime): Avoid spurious warnings of timestamps in the future due to
+	the clock's resolution being lower than file timestamps'.
+	When warning about future timestamps, report only the discrepancy,
+	not the absolute value of the timestamp and the current time.
+
+	* file.c (file_timestamp_now): New arg RESOLUTION.
+	* filedef.h (file_timestamp_now): Likewise.
+	(FILE_TIMESTAMP_NS): Now returns int.  All uses changed.
+
+2000-07-05  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (lookup_variable) [VMS]: Remove vestigial references
+	to listp.  Fixes PR/1793.
+
+2000-06-26  Paul Eggert  <eggert@twinsun.com>
+
+	* Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it.
+
+	* dir.c (vms_hash): Ensure ctype macro args are nonnegative.
+
+	* remake.c (f_mtime): Remove unused var memtime.
+
+2000-06-25  Martin Buchholz  <martin@xemacs.org>
+
+	* make.texinfo, NEWS, TODO.private: Minor spelling corrections.
+	Ran spell-check	on make.texinfo.
+
+2000-06-23  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and
+	EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE.
+	* make.h: Define these macros.
+
+	* Version 3.79.1 released.
+
+	* configure.in: Add a new option, --disable-nsec-timestamps, to
+	avoid using sub-second timestamps on systems that support it.  It
+	can lead to problems, e.g. if your makefile relies on "cp -p".
+	* README.template: Document the issue with "cp -p".
+
+	* config.guess, config.sub: Updated.
+

+
+	* vpath.c (selective_vpath_search): Check for makefile-mentioned before

+
+	* rule.c (convert_to_pattern): Don't look at the target constructed for

+
+Mon Dec 11 01:19:29 1990  Roland McGrath  (roland at albert.ai.mit.edu)
+
+	* default.c [M_XENIX]: For rules that are different for Xenix, use the

+
+	* arscan.c (ar_name_equal) [APOLLO]: Don't do `.o' hacking.  On Apollos
+	the full file name is elsewhere, and there is no length restriction (or

+
+	* main.c (define_makeflags): When there are no flags to write, make

+
+Sat Sep 29 16:38:05 1990  Roland McGrath  (roland at churchy.ai.mit.edu)

+	describing V, before recursive expansion, and pop it off afterward.
+	* job.c (child_handler): Save `variables_expanding' and clear it before
+	calling start_job, and restore it afterward.  This avoids major lossage
+	when the SIGCHLD comes in the middle of variable expansion.
+
+Mon Sep 17 14:46:26 1990  Roland McGrath  (roland at geech.ai.mit.edu)
+

+	construct_command_argv.  Takes strings SHELL and IFS instead of doing

+	simple one using /bin/sh.
+	(construct_command_argv): Do the variable expansions and call above.

+
+	* Version 3.58.8.
+
+	* main.c (decode_switches): For positive_int and floating cases, move

+
+Sat Jul 14 13:41:24 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* job.c (construct_command_argv): Always use
+	allocated_variable_expand_for_file instead of variable_expand_for_file
+	because we might be called from inside a variable expansion (for the
+	`shell' function).
+
+	* function.c (expand_function: `shell'): Free the arglist's storage
+	correctly.  construct_command_argv only allocates ARGV and ARGV[0].
+
+	* job.c (children_blocked_p_idx): Renamed to children_blocked_p_depth.
+	(push_children_blocked_p, pop_children_blocked_p): Use ..._depth

+
+Wed Jul 11 15:35:43 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* make.h (SIGNAL): New macro to replace `signal' calls.  Does arg and

+	ANSI and BSD `signal' and handler types.
+	* main.c (main), job.c (child_handler): Use it.
+
+Fri Jul  6 00:00:38 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* ar.c (ar_member_date, ar_touch): Pass 2nd arg to f_mtime.
+

+	variable makefiles (TYPE == 1), like it says in the manual.
+
+	* file.h (struct file), main.c (struct command_switch): Remove trailing
+	commas from enums.
+
+	* commands.c (execute_file_commands): Remove unused variables.

+	* ar.c: Declare ar_name_equal.
+
+	* GNUmakefile: If using gcc, add warning flags to CFLAGS.
+
+	* remake.c: Remove decl of ar_member_date, since it's done in make.h.
+
+	* remake.c (f_mtime): For ar refs, allow the archive to be found via
+	VPATH search if we're searching, and change the ar ref accordingly.
+
+	* ar.c (ar_parse_name): New global fn to parse archive-member
+	references into the archive and member names.
+	(ar_member_date, ar_touch): Use it.

+	of assuming rename_file will always set FILE->renamed (which it won't).
+
+	* vpath.c (selective_vpath_search): Only accept prospective files that
+	don't actually exist yet are mentioned in a makefile if the file we are
+	searching for isn't a target.
+

+
+	* file.c (rename_file): Prettied up long message for merging cmds.
+
+	* remake.c (update_file_1): Get each dep file's modtime, and allow for
+	it being renamed, before checking for a circular dep, since a renaming
+	may have introduced one.
+
+Tue Jul  3 18:15:01 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* ar.c (ar_touch): Don't free ARNAME since enter_file holds onto the
+	storage.
+
+	* function.c (string_glob): Don't leave a trailing space.

+	* read.c (do_define): Allow leading whitespace before `endef'.
+
+Mon Jul  2 14:10:16 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* implicit.c (pattern_search): No longer take NAME arg.  Instead take
+	ARCHIVE flag.  If ARCHIVE is nonzero, FILE->name is of the form
+	"LIB(MEMBER)"; rule for "(MEMBER)" is searched for, and LASTSLASH is
+	set to nil.  Since NAME was only non-nil when it was the archive member
+	name passed by try_implicit_rule, this change easily allows turning off
+	LASTSLASH checking for archive members without excessive kludgery.
+	(try_implicit_rule): Pass ARCHIVE flag instead of file name.
+
+	* Version 3.58.5.
+
+	* commands./c (set_file_variables): Don't kill last char of $(^D) elts.
+
+Sat Jun 30 00:53:38 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

+
+	* arscan.c (ar_scan) [sun386 && PORTAR == 1]: Treat like USGr3.
+
+Wed Jun 27 14:38:49 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* main.c (main): Put a newline on the debugging message when deciding
+	not to remake a makefile to avoid a possible loop.
+	Only decide not to remake makefiles that have commands (as well as
+	being targets and having no deps).
+
+Fri Jun 22 12:35:37 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* default.c (default_variables): Define `LINK.s' and `LINK.S'.

+	free all storage for the chopped args.
+	(start_job): Free the argument list's storage correctly.
+	construct_command_argv only allocates ARGV and ARGV[0].
+

+
+	* dir.c: Copied dirent vs direct et al mess from glob.c.
+
+	* glob.c: Replaced with updated version from djm.
+	* glob.c: Check macro DIRENT instead of _POSIX_SOURCE for <dirent.h>.
+	__GNU_LIBRARY__ implies DIRENT and STDC_HEADERS.
+
+Thu May 31 22:19:49 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* vpath.c (vpath_search): Don't stop the loop if a pattern matches but
+	the search fails.  All matching patterns have their paths searched
+	(like it says in the manual).
+
+	* make.texinfo (Rules: Directory Search: Selective Search): Say that
+	multiple `vpath' directives with the same pattern DO accumulate, not
+	supersede earlier ones.
+
+	* vpath.c (print_vpath_data_base): Increment the count of vpaths on
+	each loop iteration, rather than letting it stay zero.
+
+	* Version 3.58.3.
+
+	* job.c (block_children, unblock_children): Made static.
+	(push_children_blocked_p, pop_children_blocked_p): New functions to
+	push and pop whether children are blocked or not.
+	* job.h: Declare push_children_blocked_p, pop_children_blocked_p and
+	not block_children, unblock_children.
+	* commands.c (fatal_error_signal), job.c (wait_for_children, new_job,
+	child_execute_job), main.c (main, log_working_directory): Use sequences
+	of push_children_blocked_p (1) and pop_children_blocked_p () instead of
+	explicitly blocking and unblocking children.
+	* function.c (expand_function: `shell'): Don't unblock children.  The
+	push-pop sequence in wait_for_children makes it unnecessary.
+
+Tue May 29 21:30:00 1990  Roland McGrath  (mcgrath at helen.Berkeley.EDU)
+
+	* read.c (do_define): Don't include the last newline in the definition.
+
+	* function.c (expand_function: `shell'): Call construct_command_argv
+	before forking and don't fork if it returns nil.  Free the argument
+	list's storage before finishing.
+
+	* job.c (start_job): Free the storage for the child's argument list
+	in the parent side of the fork after the child has been spawned.
+
+	* job.c (start_job): If construct_command_argv returns nil, go to the
+	next command line.
+
+	* job.c (construct_command_argv): Use the shell if the command contains
+	an unterminated quote.
+
+Wed May 23 19:54:10 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.58.2.

+
+Thu May 17 15:25:58 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* arscan.c [USG]: Don't declare memcpy and memcmp.  <memory.h> should
+	do this anyway (and lack of declarations is harmless).
+
+	* remote-customs.c: Renamed to remote-cstms.c for System V.
+	* remote.c [CUSTOMS]: Changed accordingly.
+
+Sun May 13 14:38:39 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* GNUmakefile: Use same cmds for doc tar.Z as for dist tar.Z (so the
+	contents go in make-N.NN).
+
+Thu Apr 26 19:33:25 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* Version 3.58.1.

+
+	* job.c (init_siglist): Don't do SIGUSR1 and SIGUSR2 if they are the

+
+	* arscan.c (ar_scan): Do behavior for PORTAR == 1 and USGr3 also

+Wed Apr 11 10:00:39 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+

+	seeing if we need to expand FILE->also_make.
+
+Sun Mar  4 09:18:58 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* Version 3.58.0.
+
+	* remake.c (remake_file): Treat non-targets without commands under -t
+	the same as anything else without commands.
+

+
+	* default.c (default_variables: PREPROCESS.S): Removed $< from defn.
+
+	* main.c (main): Ignore arguments that are the empty string, rather

+
+	* main.c (main): Call construct_include_path after doing chdirs.

+
+	* make.texinfo (Implicit: Catalogue of Rules): For RCS, noted that
+	working files are never overwritten by the default rule.
+
+Thu Feb  1 17:27:54 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* rule.c (count_implicit_rule_limits): Redid loop control to not run
+	twice on freed rules.
+
+	* GNUmakefile: Made `.dep' files be architecture-specific too.
+
+	* main.c (main, log_working_directory) [USG]: Block children around
+	calls to `getwd' (actually `getcwd' on USG), because that function
+	sometimes spawns a child running /bin/pwd on USG.
+
+Tue Jan 30 14:02:50 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* function.c (subst_expand): Pay attention to SUFFIX_ONLY, putz.

+
+	* Version 3.57.6.
+
+Sat Jan 20 11:52:01 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* file.c (rename_file): Don't free the storage for the old name, since
+	it might not have been malloc'd.
+
+	* job.c (construct_command_argv): Call
+	allocated_variable_expand_for_file instead of variable_expand_for_file
+	to expand `$(SHELL)'.

+	* file.c (rename_file): Completely rewritten.  Renames in place if
+	possible, or moves FILE to a different hash bucket if there is no
+	existing file with the new name.  If there is an existing file with the
+	new name, FILE is merged into it and FILE->renamed is set to point to
+	it.
+	* variable.c (merge_variable_sets): New fn to merge two variable sets.

+	(update_goal_chain, update_file_1, check_dep): Same after update_file.
+
+	* read.c (uniquize_deps): New fn, broken out of record_files, to remove

+	special case of -j.
+
+	* make.texinfo, main.c, job.c: Changed copyright notices to include
+	1990.
+
+	* make.texinfo (Top): Fixed introductory paragraph, which said that
+	`make' itself (instead of the manual) has various chapters.
+	(Variables: Advanced: Substitution Refs): When pxref'ing about
+	`patsubst', use node `Text Functions', not `Functions'.
+	Add an xref about `patsubst' after description of $(var:a%b=c%d).
+	(Functions: Syntax of Functions): Explain why mixing delimiters in
+	function/var refs is unwise.  Clarify fn arg evaluation order.
+	(Options): Reworded sentence about `-e'.
+	(Implicit: Implicit Variables): Don't say `RM' is unused.
+	Say the dflt values for the flag vars is empty unless otherwise noted,
+	since some have defaults.
+	(Implicit: Pattern Rules: Pattern Examples): Clarified use of $< and $@
+	in first example.
+	(Implicit: Last Resort): Don't say the .DEFAULT example creates files
+	"silently".  It's automatic, but not silent.
+	(Implicit: Search Algorithm): Fixed confusing ungrammatical sentence
+	for item 5.1.
+	(Archives: Archive Update): Added missing `next' pointer.
+	(Archives: Archive Symbols): Note that GNU `ar' deals with this

+	search path (broken out of exec_command).
+	(exec_command): Take fourth arg, the shell program to use (if
+	necessary).  Use search_path for the program, and the shell program.

+	(child_execute_job): Pass shell program to exec_command.
+	* main.c (main): Ditto.

+
+	* function.c (expand_function: `shell'): Don't clobber BUFFER and then
+	try to free it.
+
+	* remake.c (update_file_1): Took code to force remake of nonexistent
+	deps out of #if 0, and changed the test to nonexistent non-intermediate
+	deps.  In version 4, I think removing this test completely will
+	implement the new feature that if a: b and b: c and c is newer than a,
+	b need not be remade.
+

+	being updated.  (The exact opposite test was here before; why???)
+	(update_file_1): Set a dep's `changed' member after updating it if it
+	is phony and has commands (because they will then always be executed).
+
+Thu Nov  9 13:47:12 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

+
+	* main.c (main) [hpux]: hpux == HPUX.

+
+Mon Oct 23 14:34:23 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.56.7.
+
+	* remake.c (update_file_1): If, after being updated, any dependency

+
+	* function.c (string_glob): Don't add spaces after file names that

+	deps from the chain.
+	* main.c (main): Do it here, before calling update_goal_chain.
+

+
+	* remake.c (update_file_1): Don't always remake if FILE has cmds but no

+	done for double-colon targets, but that's what Unix make does.)
+
+	* load.c [LDAV_BASED] (load_average): Write error messages if the
+	various system calls fail.  Keep track of if we've failed before.
+	The first time we fail, write a message saying -l won't be enforced.
+	The first time we succeed after having failed, write a message saying
+	-l will be enforced again.
+
+	* remake.c [USG]: Don't #include <sys/file.h>
+
+	* load.c [generic Unix LDAV_BASED]: #include <fcntl.h> #ifdef USG,

+
+	* job.c [USG && !USGr3 && !HAVE_DUP2]: Remove redundant
+	#include <errno.h> and declaration of `errno'.
+	[...] (dup2): Fixed so it won't always lose.
+
+	* default.c (default_suffix_rules: .texinfo.dvi): Copy, rather than
+	move, the aux and index files, so the TeX run can use them.
+
+	* compatMakefile: Remove redundant comment.
+
+	* load.c [generic Unix LDAV_BASED]: Include <a.out.h> instead of
+	<nlist.h>, since the `struct nlist' declaration in <nlist.h> varies
+	more than the one in <a.out.h>.
+	(load_average): Use the `n_un.n_name' field of the `struct nlist',
+	since the <a.out.h> declaration uses the union.
+
+	* main.c (main): For the temporary files made for stdin makefiles, set
+	the `intermediate' and `dontcare' flags.
+	* file.c (remove_intermediates): Don't print any messages for files

+	intermediate and `dontcare' will be the temporary files made for stdin
+	makefiles.)
+
+	* job.c (exec_command): Made global.
+	* job.h: Declare it.
+	* main.c (main): Use exec_command when re-execing.
+
+	* make.h: Declare environ.

+	(install): Depend on $(mandir)/make.$(manext).
+	($(mandir)/make.$(manext)): Depend on make.man and copy it to $@.
+	($(bindir)/make): Use `make' rather than $<; so Unix make can grok it.

+
+	* remake.c (remake_file): Cleaned up.
+
+	* commands.c (execute_file_commands): If the commands are empty, set
+	FILE->update_status to zero before returning.
+
+	* remake.c (notice_finished_file): Set `last_mtime' fields to zero
+	instead of calling name_mtime; file_mtime will do that later if anybody
+	cares.

+
+	* make.texinfo (Rules: Wildcards: Wildcard Examples): Give this node a

+
+	* remake.c (update_file_1): In the loops that call update_file on the
+	deps, compare modtimes before and after (unless deps are still being
+	made) and set the deps' `changed' members.  Do not set the `changed'
+	members in the loop that prints the newer/older debugging messages.
+	* remake.c (update_file_1): If no deps changed and FILE has no
+	commands, decide it doesn't need remaking.
+
+	* remake.c (update_file_1): Print a debugging message if we take

+	using the shell.
+
+	* job.c (start_job): In the child side, call unblock_children instead
+	of sigsetmask.
+
+	* remake.c (notice_finished_file): Under -n or -q, always increment
+	files_remade for non-phony files.
+
+	* rule.c (intall_pattern_rule): Use find_percent.
+

+	patterns.
+
+	* function.c (pattern_matches): Take new arg PERCENT, a pointer into
+	PATTERN where the % is.  If PERCENT is nil, copy PATTERN into local
+	space and run find_percent on it.
+	(expand_function: `filter', `filter-out'): Pass new arg to
+	pattern_matches.
+	* read.c (record_files): Pass PATTERN_PERCENT to pattern_matches for
+	static pattern rules.  Save the percent pointer into implicit rule

+	* GNUmakefile: Added a rule to edit the version number in
+	README.template and README-doc.template, producing README and
+	README-doc.
+
+	* remake.c (update_goal_chain): If -n or -q is in effect for a
+	makefile, and it got updated, don't change STATUS, so we can still
+	return -1 (meaning nothing was done).  This avoids an infinite loop on
+	"make -n Makefile".
+
+Sat Aug 12 23:14:24 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* remake.c (notice_finished_file): Treat -q the same as -n.

+
+Fri Aug 11 04:09:14 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* function.c (expand_function): Removed unused variables.

+
+	* job.c (exec_command): Fixed to not ignore the last path component and

+
+	* remake.c (remake_file): If FILE has no commands and is a target,
+	don't set its time to now.  The time gets reset by notice_finished_file
+	anyway, and it isn't needed since check_dep checks for nonexistence.
+
+	* Version 3.54.6.
+
+	* read.c (read_makefile): Don't read off the end of the string after an
+	`include'.
+
+	* job.c (exec_command): New function to search the path for a file and
+	execute it.
+	(start_job): Use exec_command rather than execvp.
+
+	* read.c (read_makefile): Expand `include' directive args before
+	parsing them.  Allow trailing whitespace after filename.

+
+	* remake.c (notice_finished_file): Don't get the new modtime of phony
+	files.
+
+	* remake.c (remake_file): Run commands instead of touching under -t if
+	FILE->cmds->any_recurse is set.
+
+	* commands.h (struct commands): Add new member `any_recurse', to be set
+	nonzero if any `lines_recurse' element is nonzero.
+	* commands.c (chop_commands): Set the `any_recurse' member.
+
+	* commands.c (execute_file_commands): Split chopping of commands into

+	directory names.
+
+	* job.c (wait_for_children): Changed "waiting for children" message to
+	"waiting for unfinished jobs".

+	* read.c: Declare getpwnam.
+
+	* glob.c: Use <dirent.h> if DIRENT is defined.
+	[USG]: Don't declare memcpy, since <memory.h> does.
+
+Fri Jul  7 20:53:13 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* misc.c (collapse_line): Copy the line over in the right place.

+Fri Jul  7 18:33:24 1989  Roland McGrath    (fsf at void.ai.mit.edu)
+
+	* remake.c: Conditionalize inclusion of <sys/file.h> on not

+
+	* job.c: If WTERMSIG is defined by <sys/wait.h>, define WAIT_T as int,
+	and don't define other macros; this covers HP-UX.
+	If WTERMSIG is not defined, use int or union wait based on USG and
+	HAVE_SYS_WAIT; this covers BSD and SysV.
+
+	* Version 3.54.3 (alpha).
+
+	* job.c [USG and not USGr3]: Include <errno.h> and declare errno.

+	* job.c (unblock_children [USG]): Declare child_handler.
+
+	* job.c: Renamed WRETCODE to WEXITSTATUS.

+	* expand.c (variable_expand): When terminating the variable expansion
+	buffer, use variable_buffer_output instead of a simply zero store,

+
+Wed Jun 28 16:53:47 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* Version 3.54.
+
+	* default.c (default_suffixes): Added `.ln'.

+
+	* job.c (start_job): If there are no more commands, return nonzero
+	under -n or -t.
+
+	* compatMakefile (make): Pass `-f' to mv.
+
+	* GNUmakefile: If `ARCH' or `machine' is defined, make $(ARCH)/*.o and
+	$(ARCH)/make instead of *.o and make.
+
+	* function.c (string_glob): Don't try to use freed storage!
+
+	* read.c (readline): If there is only one byte of space in the buffer,
+	enlarge the buffer before reading more.
+

+
+Sun Jun 18 13:07:45 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* GNUmakefile (depend): Split commands into two lines so they won't be
+	so long when variable-expanded.
+
+	* compatMakefile: Documented MINUS_C_MINUS_O meaning.  The line

+
+Sat Jun 17 22:56:54 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* Version 3.52.
+
+Mon Jun 12 17:45:11 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

+
+Sun Jun 11 12:00:52 1989  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* Version 3.51.
+
+	* make.texinfo (Features): Noted 1003.2 requirement of `+' meaning.
+

+	line, listing all files.
+
+	* read.c (read_makefile): Don't free the storage for the passed
+	filename, since it might not be malloc'd.  When doing an included

+	(read_makefile): Allocate storage for the makefile name in the
+	`struct file' in read_makefiles.
+
+	* make.texinfo (Running: Instead of Execution): Document the effect of

+	backslash-newlines.
+	(start_job): Collapse backslash-newlines after printing the line.
+
+	* commands.c (start_job): Don't collapse backslash-newlines here.
+	(execute_file_commands): Collapse backslash-newlines before chopping
+	the commands up into lines.
+
+	* commands.c (set_file_variables): Initialize the length counters for

+Sat Jun 10 00:11:25 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* remake.c (library_file_mtime): Check for libNAME.a in the current

+
+	* variable.c (print_variable_set): Don't write "# Variables", and write
+	fewer blank lines.
+	(print_variable_data_base): Precede the variables with "# Variables".
+
+	* make.c (main): Print the data base under -p after doing everything
+	else, just before exitting.  This way it gets info determined in
+	updating the goal targets.
+
+	* variable.c (print_variable_data_base): Split into print_variable,
+	which prints one variable, and print_variable_set, which prints a set.
+	Replaced with a call to print_variable_set for the global set.

+	variables.
+
+	* file.c (print_file_data_base): Call print_file_variables to print

+	the $^ and $? variables!!!
+
+	* make.texinfo (Implicit: Pattern Rules: Automatic): Document new D and
+	F versions of $^ and $?.
+
+	* commands.c (start_job): In the child fork, use getdtablesize and a
+	loop to close all file descriptors other than 0, 1, and 2.  We need to
+	do this since not only the bad stdin pipe, but also some directories,
+	may be open.
+
+	* commands.c (start_job): Use fork instead of vfork, because a vfork
+	parent and child share file descriptors, and our child needs to diddle
+	with stdin.
+
+	* variable.c (initialize_file_variables): When created a new variable
+	set, zero out the hash table.
+
+	* variable.c (target_environment): Don't use variables whose names are
+	not made up of alphanumerics and underscores.
+
+	* remake.c (update_file_1): Set the `parent' member of each dependency
+	to FILE before updating it.
+
+	* file.h (struct file): Add `parent' member.
+
+	* variable.c (initialize_file_variables): Don't take second arg PARENT.
+	Use FILE->parent instead.  If FILE->parent->variables is nil, recurse
+	to initialize it.
+
+	* variable.h: Declare {allocated_}variable_expand_for_file.
+
+	* variable.c (allocated_variable_expand): Now
+	allocated_variable_expand_for_file, calling variable_expand_for_file,
+	and taking second arg FILE.
+	(allocated_variable_expand): New function, a wrapper around
+	allocated_variable_expand_for_file, passing a nil second arg.
+
+Fri Jun  9 12:11:45 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* commands.c (start_job): On the child side of the fork, always close

+
+	* commands.c (struct child): New member `environment', to hold the
+	environment for the child.
+	(execute_file_commands): Set the new childs `environment' member to nil
+	before calling start_job.
+	(start_job): Set up CHILD->environment before running the commands if
+	it is nil.
+
+	* make.c (main): Don't call new_environ.  `shell' functions will now be
+	run with the environment make was called with.
+
+	* commands.c (child_handler): Don't check C->command_ptr before calling
+	start_job since we now have to check C->file->cmds->command_lines and
+	it's easier to let start_job handle all that.
+
+	* commands.c (struct child): New member `command_line', to hold an
+	index into file->cmds->command_lines.
+	(execute_file_commands): Set the new child's `command_line' to 0 and
+	its `commands' and `commands_ptr' to nil.
+	(start_job): When CHILD->command_ptr runs out, increment
+	CHILD->command_line and run the corresponding line from
+	CHILD->file->cmds->command_lines.  Run it even under -t, -q, or -n if
+	the CHILD->file->cmds->lines_recurse element for that line is set.
+
+	* commands.c (execute_file_commands): Chop CMDS up into lines, setting
+	its `command_lines' and `lines_recurse' members, if it wasn't already
+	chopped.
+
+	* commands.h (struct commands): New members `command_lines' and
+	`lines_recurse'.  The first is an array of chopped-up lines; the second
+	is an array of flags, each nonzero if the corresponding line is
+	recursive.
+
+	* variable.c (variable_expand_for_file): If FILE is nil, just do a
+	vanilla variable_expand.
+	(expand_function: `shell'): Pass second arg (as nil) to
+	construct_command_argv.
+
+	* commands.c (construct_command_argv): Use variable_expand_for_file on
+	`$(SHELL)' and `$(IFS)' instead of lookup_variable to check those
+	variables.  This handles file-local and recursive values correctly.
+	To support this, take an additional argument FILE.
+
+	* variable.c (initialize_file_variables): New function to initialize
+	FILE's variable set list from PARENT's setlist.  PARENT is the
+	immediate dependent that caused FILE to be remade, or nil if FILE is a
+	goal.  (When user-level per-file variables are implemented, PARENT
+	should be passed as nil when defining per-file variables.)
+
+	* variable.c (variable_expand_for_file): New function to expand a line
+	using the variable set of a given file, and reporting error messages
+	for the file and line number of that file's commands.
+
+	* variable.h: Don't declare lookup_variable_for_file.
+
+	* variable.c (lookup_variable_*): Turned back into lookup_variable.  It
+	now uses current_setlist.
+	(global_setlist): New static `struct variable_set_list', a setlist
+	containing global_variable_set.
+	(current_setlist): New static `struct variable_set_list *', a pointer
+	to the current variable set list.
+	(define_variable): Define in the current top-level set, not the global
+	set.
+
+	* commands.c (set_file_variables): New function to set up the automatic
+	variables for a file in its own variable set.
+	(execute_file_commands): Use set_file_variables.
+
+	* variable.c (new_environ): Replaced with target_environment, taking an
+	argument FILE, and returning an environment for FILE's commands.
+
+	* variable.c, variable.h: Remove all global special variable pointers.
+
+	* variable.c (define_variable_for_file): New function like
+	define_variable, but takes additional arg FILE, and defines the
+	variable in the variable set at the top of FILE's chain.

+
+	* make.c (main): Fixed bug in deciding to increase space for

+
+Fri May 26 15:48:01 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* read.c (multi_glob): Use allocated_expand_variable for checking

+
+	* variable.c (allocated_expand_variable): New function to do variable
+	expansion in an allocated buffer, rather than the static one.

+	directives.  Nonrecursive variable definitions containing newlines, and
+	variable names containing :, =, or newlines, will come out garbled.

+
+	* variable.c (patsubst_expand): Take two new args: PATTERN_PERCENT
+	and REPLACE_PERCENT.  Each of these, if non-nil, means that PATTERN

+
+	* read.c (pattern_p): New function to search for an unquoted % in a

+	(record_files): Use pattern_p to check for implicit rules.
+	(read_makefile): Use pattern_p to check for static pattern rules.

+
+	* rule.c (default_variables): Set F77 to $(FC) and F77FLAGS to

+
+	* commands.c (construct_command_argv): Don't make the 0th element of

+
+	* commands.c (block_children, unblock_children): Make these globally
+	visible (not `static').
+	commands.h: Declare block_children and unblock_children.
+
+	* variable.c (expand_function: `shell'): Use

+	`shell_functon_completed' is reset to 0.
+

+	* version.c: Removed copyright notice, since this is a one-line file.

+	of child_handler).

+	Also support Modula-2 compilation (suffixes .sym, .def, and .mod).
+	Ratfor Yacc support is gone, since nobody has yacc -r.
+	All EFL support is gone, since nobody uses EFL.
+
+	* ar.c, arscan.c: Don't assume `long int' and `int' are the same.
+
+	* commands.c [USG]: Fixed wait status bit encoding.
+	[USG and not USGr3] (dup2): Define this for SysVr2.
+
+	* make.h, dep.h, make.c [iAPX286]: Make allowances for this

+	of a recursive variable when it is nod longer needed.
+
+	* variable.c (variable_expand): When checking for `$($(foo))', use

+
+	* make.c (struct stringlist, main, decode_switches): Changed `index'
+	member to `idx'.
+
+Sat Dec 24 16:02:32 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* commands.c (wait_for_children [USG]): Handle SIGCLD with SIG_DFL,
+	rather than SIG_IGN.  Ignoring SIGCLD reportedly makes wait return -1.
+
+	* arscan.c [USGr3]: Define PORTAR to 1 (as with sun386).
+	(ar_scan [USGr3]): Remove trailing slashes from member names.
+
+Thu Dec 22 17:54:05 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* make.texinfo (Makefiles: Overriding Makefiles): New node
+	documenting use of .DEFAULT to have one makefile defer unmakeable
+	targets to another.

+
+	* make.c (struct command_switch, command_switches, et al): New
+	member `noarg_value', if not nil, ptr to value to use if no arg is

+	call start_remote_job to start the job rather than fork and exec.
+	(child_handler):
+
+	* commands.c (execute_file_commands): Moved load average checking to
+	start_job.
+
+	* commands.c (child_handler: USG): Record the pid wait returns.

+	* commands.c (execute_file_commands): If max_load_average > 0, and
+	we have children running, don't start up another child until the
+	load average goes below max_load_average.
+
+	* make.c: New variable `max_load_average'.

+Thu Dec 15 15:22:08 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* Makefile: Renamed to oldMakefile.
+	* GNUmakefile: Make Makefile from oldMakefile and depend.
+
+	* read.c (read_all_makefiles): When putting the default makefiles in
+	the read_makefiles chain so they will be remade, put them in the
+	right order.
+

+
+	* make.h: Don't declare construct_makeflags.
+
+	* make.c (main): Set up MAKEFLAGS and MFLAGS and make an environment
+	both before and after reading the makefiles, so the makefiles can
+	use them and possible change them, and later children will get the

+	(construct_makeflags): Replaced with define_makeflags (static void),
+	which defines the two variables.
+	* variable.c (define_automatic_variables): Don't define MAKEFLAGS
+	and MFLAGS.
+
+Mon Dec 12 14:40:31 1988  Roland McGrath  (mcgrath at helen.Berkeley.EDU)
+
+	* Version 3.27.
+
+	* commands.c (child_handler): Reset the handler to ourselves when
+	called for USG, since it has no safe signals.
+
+	* commands.c: For USG, use an int rather than a `union wait' for
+	wait calls, and dissect it with bitmasks.
+	(child_handler): No wait3 system call in USG.  Since we can't
+	protect from hanging, always return immediately if we have no
+	children we know about and we're not running a `shell' function.
+	(There is still the danger of hanging waiting for a child that died
+	without our being notified.)
+
+	* remake.c: Include <fcntl.h> instead of <sys/file.h>.  What we need
+	is really in <fcntl.h>, and while BSD <sys/file.h> includes
+	<fcntl.h>, USG doesn't.
+
+	* make.c (main): Figure out the program name before doing anything
+	which might need it (in a call to error or fatal).
+
+	* dir.c, glob.c: Use `struct dirent' and <dirent.h> for USGr3.

+
+	* Version 3.26.
+
+	* dir.c (find_directory, dir_file_exists_p): Keep track of how many
+	directories we have open and don't let it be more than
+	MAX_OPEN_DIRECTORIES (currently 10).
+
+	* variable.c (expand_function: `foreach'): Use expand_argument
+	rather than variable_expand so each repetition doesn't clobber the
+	last!!!
+
+Mon Dec  5 15:58:46 1988  Roland McGrath  (mcgrath at hecuba.Berkeley.EDU)
+
+	* Version 3.25.
+
+	* Makefile: Define `install' target.
+
+	* GNUmakefile: Don't include GNUmakefile or depend in the

+
+	* remake.c (check_dep): Set *MUST_MAKE_PTR nonzero if a dependency
+	doesn't exist.
+
+	* ar.c (ar_member_date, ar_touch): Make sure the modtime of the
+	archive file itself is known before we fetch or change the modtime
+	of one of its members.
+
+	* read.c (read_makefile): Expand variable and function references
+	before parsing rules so variable can contain special characters
+	(colons and semicolons).

+Sat Nov 26 11:36:31 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* variable.c (expand_function: `filter', `filter-out'): Fixed so
+	that filter-out works right.
+
+	* variable.c (expand_function: `filter', `filter-out'): Made these
+	functions use each word of their first argument as a pattern.
+
+Fri Nov 25 10:51:47 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.24.
+
+	* read.c (record_files): If a target is listed more than once in a
+	single rule (that defines commands), give a warning message rather
+	than the counter-intuitive message saying commands were already
+	defined (in the same place).
+
+	* make.c (fatal, error): Made them both take 6 args since there is
+	at least one error message that need that many.  Too bad vfprintf is
+	not universal!
+
+	* Version 3.23.
+
+	* read.c (read_makefile): Moved the construction of the `struct
+	commands' into record_files.  Call record_files before recursing for an
+	included makefile so the higher-up will determine the default goal.
+	(record_files): Take arguments COMMANDS, COMMANDS_IDX and
+	COMMANDS_STARTED and construct a `struct commands.
+
+Thu Nov 24 14:36:33 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.22.
+
+	* make.c (main): Made it a fatal error if we can't move back to the
+	directory we started in before re-execing.
+
+	* make.c (main): Get the current directory before doing anything
+	else, so we know it even if we don't need it for the value of
+	`MAKE', since we might want it when re-execing.
+
+Wed Nov 23 13:34:44 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* Version 3.21.
+
+	* read.c (record_files): Eliminate duplicate deps in a chain.
+
+	* variable.c (expand_function: `sort'): Pass the right number to
+	qsort, not one less.
+
+	* remake.c (remake_file): Always call notice_finished_file if
+	FILE->command_state == cs_finished.
+
+	* commands.c (execute_file_commands): Call notice_finished_file to
+	set FILE's status correctly when start_job fails (because it's out
+	of commands or running under -n).
+
+Fri Nov 18 15:31:12 1988  Roland McGrath  (mcgrath at saffron.Berkeley.EDU)
+
+	* Version 3.20.
+
+	* remake.c (update_file_1): Set the `update_status' of FILE to
+	nonzero and set FILE's `updated' bit if we have decided to give up

+	* GNUmakefile, Makefile: Fixed a typo in a comment.

+	so that it really works, now that parens are counted.
+
+	* remake.c (update_file_1): Set FILE's `updated' flag after calling
+	remake_file if it failed or finished immediately.
+
+	* remake.c (update_file): Use the `updated' flag rather than the
+	command state to decide if a file was fully considered, and
+	therefore might give an "up to date" message.
+
+	* variable.c (expand_function): Made all functions that take more
+	than one argument count parens of the appropriate flavor in their
+	args and ignore commands nested in parens.

+	* GNUmakefile: Added an explicit rule for make.dvi since the
+	built-in .texinfo.dvi implicit rule is screwed up.
+
+	* rule.c (default_suffix_rules): Added a comment that the
+	.texinfo.dvi rule does not work because of an ahem, feature of Make
+	that at some point will be fixed--er, enhanced to alleviate this
+	difficulty.
+
+	* rule.c (default_suffix_rules): Fixed Texinfo -> DVI rule (again).
+
+	* make.texinfo (Commands: Execution): Documented new competing for

+	`reading_lineno_ptr' after recursing for an included makefile.
+
+	* GNUmakefile: New GNU Make-specific makefile that does everything

+	to try to work with Unix make.
+

+	files used for standard input makefiles.
+
+	* make.c (main): Don't turn standard input into a broken pipe.
+
+	* commands.c (start_job): Keep two extra file descriptors around: a
+	good standard input, and a bad one that reads from a broken pipe.
+	On the child side of the fork, if there are other children, give
+	this one the broken pipe so they won't compete; if this is the only
+	one, give it the good standard input.
+
+	* make.h: Declare notice_finished_file.
+
+	* commands.c (execute_file_commands): Use noticed_finished_file
+	after waiting for the child when there is only one job slot.
+

+
+	* commands.c (child_handler, execute_file_commands): Use new
+	variable `job_slots_used' to record the number of jobs currently
+	running, rather than diddling with `job_slots'.
+	(execute_file_commands): Increment `job_slots_used' before calling
+	start_job and decrement it on failure to avoid race condition.
+	If there is only one job slot, wait for the child to finish and
+	return its status so commands are run in linear order, as if there
+	were no parallelism.

+
+	* file.h (struct file): Add `dontcare' member.
+
+	* read.c (read_all_makefiles): When no default makefiles are found,
+	put the names of all those tried in the `read_makefiles' chain so
+	they will be updated if possible, giving their `struct dep's'
+	`changed' members the value of 0 so we won't care if they cannot be
+	found or remade.
+
+	* make.texinfo (Makefiles: Remaking Makefiles): Documented that
+	default makefiles will be remade if not found.
+
+	* read.c (read_all_makefiles): If no default makefiles can be found,
+	go through the list of default names, trying to make one, stopping
+	if one is made.
+
+	* remake.c (remake_file): Set STATUS to 0 after successfully touching.
+
+	* dir.c (file_impossible, file_impossible_p): Don't clobber FILENAME

+	directories, each containing a chain of `struct dirfiles', one for
+	each file (real or impossible).
+	(dir_load): Removed.

+	named directory and return it (possibly creating a new one).
+	(dir_file_exists_p): Read the directory on the fly if its stream is
+	still valid (and ever was) if the file we're looking for is not

+
+	* Makefile: Don't make the uncompressed tar file.
+
+	* variable.c (expand_function: `shell' function): Made it not expect

+
+Thu Oct  6 17:52:35 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.11.

+
+	* make.c (main): Put a ".PHONY: /tmp/foo" line in front of temp

+
+	* read.c (read_makefile): Don't check for FILENAME being "-".
+	(read_all_makefiles): Set each element of MAKEFILES to the name put

+
+	* make.c (main): For each `-f' flag with arg `-' (standard input),

+
+Sat Oct  1 00:19:59 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

+
+	* variable.c (new_environ): Don't put default variables (origin

+
+	* read.c (read_makefile): Don't add FILENAME to the chain of read
+	makefiles if it's "-" (standard input).

+	added to the `read_makefiles' `struct dep' chain.

+
+Fri Sep 30 18:56:20 1988  Roland McGrath  (mcgrath at nutmeg.Berkeley.EDU)

+	for a normal makefile, 1 for MAKEFILES variable or 2 for an included
+	makefile.  Add a `struct dep' containing the name of the makefile
+	(as it was found in the search path for type 2s), and TYPE in the
+	`changed' member to the global `read_makefiles' chain.
+
+	* make.h, rule.c (displace_pattern_rules,
+	add_displaced_pattern_rules): Removed these functions.
+
+	* read.c (read_makefile): Variable-expand the name of an `include'd
+	makefile before calling find_makefile on it.
+
+	* file.c (snap_deps): If the `struct file' for a `struct dep'

+	it to nil (since this info is in the `struct file').
+

+	command state to `cs_finished'.
+
+	* remake.c (update_file): Don't write the "up to date" message if

+	put in the the new `struct child's `environ' member.
+	(child_handler): When freeing a child, free its `commands' member, the
+	elements of its `environ' array and its `environ' member itself.
+	(start_job): Set `environ' to the child's `environ' member before

+
+	* remake.c (update_file): Don't give a "is up to date" message
+	unless no files were remade and the state went from `cs_not_started'
+	to `cs_finished', so repeat calls to finish jobs won't get the message.

+
+	* make.c (main): Use wait_for_children rather than child_handler.
+
+	* commands.c (wait_for_children): New function to block waiting for

+	sequence after an ignored error.
+
+	* remake.c (update_file): Don't print "`foo' is up to date" messages

+	* remake.c (update_file_1): Pass the file name to name_mtime, not
+	the bloody `struct file', dammit!!
+
+	* commands.c (child_handler): Print out the "*** ..." error message
+	when not under -i.  (I somehow forgot this.)
+
+	* remake.c (update_file_1): Use name_mtime rather than file_mtime to

+	Make all switches that take string args allow them right after the
+	switch letter.
+
+	* commands.c (child_handler): Check for a child being the `shell'
+	function's command returning and set the global variable for
+	expand_function to check.
+
+	* variable.c (expand_function): For the `shell' function, instead of
+	waiting for the child shell ourselves, let child_handler do it and
+	loop around waiting for something to happen.

+	starting a new job to run file commands.
+

+	goal-making loop.
+
+	* commands.c (child_handler): When commands finish, set the
+	corresponding file's `update_status' and `updated' flags as
+	appropriate, and reset the modtimes of the file and any `also_make'
+	files it has.
+
+	* remake.c (remake_file): Don't re-set `last_mtime' and set `updated'.
+
+	* commands.c (fatal_error_signal): Don't swallow all the children

+	(construct_makeflags, decode_switches, decode_env_switches):
+	Handle`positive_int'-type switches.
+
+	* glob.c (glob_vector): Rename local variable `vector' to `VeCtOr'.
+	This is said to avoid a conflict with some system's global `vector'
+	variable.
+
+	* variable.c (expand_function): Made the `shell' function use
+	construct_command_argv and do its own child control and piping.
+
+	* make.c (main): Turn standard input into a broken pipe after
+	reading in all makefiles (the last time it will be needed).
+
+	* commands.c (struct child): Remove `pipe_fd' member.  We don't use
+	pipes any more.
+	(start_job): Return 0 for success, 1 or failure (rather than void).
+	Don't use pipes.  Don't turn the child's stdin into a broken pipe.

+	`noerror' members to keep track of info about a command thread.
+	(start_job): New function to start a job and update the argument
+	`struct child' to reflect its status.

+	Made it use new start_job function.
+

+	discarded rule.  It may be used in more than one place.
+
+	* commands.c (execute_command_line): Made it not try to delete the
+	possibly partly-made file.  The child_handler function will do this.
+	(fatal_error_signal): Ditto + call kill_children.
+
+	* make.h: Declare job_slots.
+
+	* make.c (main): Collect goals in a dep chain and run through this
+	chain waiting for a child, eliminating finished goals, updating all
+	remaining goals, and quitting if they fail and not -k.
+
+	* commands.c (child_handler): If called with SIG < 0, - SIG is the
+	max number of children to bury.
+
+	* commands.c (child_handler): If called with SIG as zero,

+
+	* remake.c (update_file_1): Use the `command_state' member of FILE
+	and its dependencies to determine what commands are running, what to
+	do, etc.  If commands or dep commands are running when we are

+	time we were called, return their status.
+
+	* commands.h: Declare kill_children.
+
+	* commands.c: Define `struct child' to keep track of child
+	processes, with the chain in `children'.
+	(child_handler): New function to catch child-termination signals
+	(SIGCHLD, or SIGCLD for USG), store the returned status in the
+	appropriate structure, take the now-obsolete `struct child' out of
+	the chain, and free its storage.
+	(execute_file_commands): Put all of the stuff invloving running the
+	commands into new function run_file_commands.  Execute_file_commands
+	now does process management for the commands, while
+	run_file_commands (which is run in a subprocess) runs the commands.
+	(kill_children): New function to kill all running children by
+	sending them signal SIG.  If there are any children still living
+	after they are all sent SIG, they are all sent SIGKILL.
+
+	* make.c (main): Catch SIGCHLD (SIGCLD for USG) with child_handler.
+
+	* commands.h: Declare child_handler function.
+
+	* commands.c (execute_file_commands): Check the `command_state'
+	member of FILE and return 0 if it is `cs_running' or

+
+	* commands.c (execute_command_line): Add `$' to the list of
+	characters special to the shell.

+	build_vpath_lists to read_all_makefiles.
+
+	* read.c (read_all_makefiles): Install the default pattern rules
+	before checking to remake the makefiles, displace these rules before

+
+	* remake.c (library_file_mtime, f_mtime): Removed use of last two
+	arguments to vpath_search.
+
+	* rule.c (pattern_search): Removed use of last two arguments
+	to vpath_search.
+
+	* vpath.c (vpath_search, selective_vpath_search): Removed unused
+	DIRPREFIX and DPLEN args.
+
+	* read.c (read_makefile): Also turn off -n when updating makefiles.
+
+Tue Sep 20 17:01:10 1988  Roland McGrath  (mcgrath at pepper.Berkeley.EDU)
+
+	* Makefile: Put tags files in the tarfile.
+
+	* read.c (read_makefile): Get the modtime of the makefile via a stat
+	call so that a later file_mtime call won't do VPATH search for it.
+
+	* read.c (read_makefile): Don't turn off -t and -q if the makefile
+	was a command-line target.
+
+	* make.c (main): Enter command-line targets as files and set their
+	`cmd_target' members.
+
+	* file.h (struct file): Added `cmd_target' member.
+
+	* read.c (read_makefile): Temporarily turn off -t and -q while
+	updating makefiles.
+
+	* make.c (main): Don't use arg 0 from other_args (which is now
+	argv[0]; i.e., the program's name).
+
+	* read.c (read_makefile): Only return nonzero if commands were
+	actually run to remake the makefile.
+
+	* remake.c (update_file_1): Set FILE->updated to -1 if no commands
+	were actually run (because no update was done or -t was given).
+
+	* make.c (decode_switches): Fixed bug wherein xrealloc was passed
+	bad args if it tried to expand other_args->list.
+
+	* read.c (read_all_makefiles): Made it not look at the `MAKE'
+	variable, just use argv[0].
+
+Sun Sep 18 17:34:11 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* read.c (rerun_make): New function to re-exec make.
+
+	* make.c (construct_makeflags, construct_argv): New functions to
+	construct the `MAKEFLAGS' variable and to construct an arg list from
+	parsed info.
+
+	* read.c (read_makefile): New arg UPDATEIT, if nonzero, says to
+	update the makefile as a target before reading it in.  When reading
+	included makefiles, pass this as zero.  Now returns nonzero if the
+	makefile was updated, zero if not.
+	(read_all_makefiles): Pass a nonzero UPDATEIT arg to read_makefile
+	for all default and -f makefiles and all makefiles from the
+	`MAKEFILES' variable.  If any of the makefiles has changed, re-exec

+	under -p.
+
+	* commands.c (execute_file_commands): Allocate one byte for each of

+
+	* read.c (record_files): Made it not free the storage for the name
+	if it started with `./' and was therefore not quite the same as in
+	the `struct file'.
+
+	* read.c (record_files): If commands were specified twice, the error
+	message specifies in what files and at what line numbers.
+
+	* make.c (main): If any of the signals we usually fatal on were
+	ignored by the parent (probably a shell), ignore them.
+
+	* make.c (main): Print version info for -v, -p, or -d.

+
+	* file.c: Increased number of hash buckets to 1007.
+
+	* rule.c (count_implicit_rule_limits): Moved comptation of

+	`maxsuffix', and must be called before count_implicit_rule_limits.
+
+	* rule.c (pattern_search): If an existent (non-intermediate)
+	dependendency was found via a terminal rule, set its
+	`tried_implicit' flag, so it will never have implicit rule search done.

+
+	* make.texinfo: Documented `shell' function.

+
+	* rule.c (default_pattern_rules, default_variables): Made it use
+	`$(AR)' for `ar r' (to put files in archives).
+
+	* vpath.c (build_vpath_lists): Made it recursively expand the
+	`VPATH' variable (by using variable_expand instead of lookup_variable).
+
+	* read.c (conditional_line): Made it not swallow whitespace after
+	the comma in an `ifeq' using the `(a,b)' syntax.
+
+	* rule.c (count_implicit_rule_limits): Made it not crash if a
+	pattern rule dep begins with `/'.
+
+Sun Aug 28 15:51:12 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)

+
+	* make.c (collapse_continuations): Bug fix from RMS.
+
+	* rule.c (install_default_pattern_rules): Made it set the

+
+	* rule.c (pattern_search): Fixed putting `also make' targets into
+	file strucutres.
+
+	* read.c (record_files): Fixed bug which made double-colon entries
+	make it read off into space.
+
+	* make.c (decode_switches): Made it understand `ignored' switches

+	directive) matched the filename.
+
+Sat Aug 13 14:20:46 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (decode_switches, main): Made the command switches be

+	argc and argv.
+	(construct_include_path): Ditto.
+

+
+	* make.texinfo: Minor editorial changes.
+
+	* read.c (read_makefile): Minor speed improvement by freeing and
+	then mallocing something rather than reallocing it to avoid the
+	unnecessary bcopy.
+
+Thu Aug 11 00:10:43 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.texinfo: Fixed some unquoted @'s.

+
+Wed Aug 10 00:55:39 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* variable.c (print_variable_data_base): Fixed bug which made -p
+	dump core.  (This was a really idiotic bug.)
+
+	* rule.c (pattern_search): Fixed a bug which made it make the
+	`also_make' member of the file in question nil if the first of
+	the successful rule's targets was the matching one.
+	Made it use only as much storage as necessary in the `also_make'
+	member.
+	(create_pattern): Made it use only as much storage as necessary in
+	the `lens' and `suffixes' members of the created rule.
+
+	* remake.c (library_file_mtime): Made it `static'.

+	<errno.h>'s, but not all.
+
+	* file.h (struct file): Added `also_make' member for multiple-target
+	implicit rules.
+	* rule.c (pattern_search): Made it put the names of files updated by
+	the given file's commands in its `also_make' member.
+	* remake.c (update_file_1): Made it mark the files in a file's
+	`also_make' member as updated when the file is updated.

+	was no space before the = or :=.
+
+	* make.texinfo (Features): Made the changes which were made in RCS
+	revision 2.7 but somehow lost since then.  Added -W.

+	variables with origin `o_default'.
+
+	* make.texinfo: Documented -W.
+
+	* make.c (decode_switches, main): Added the -W flag to give files a

+	that are built into the default ruleset.
+
+	* read.c (record_file): Made .SUFFIXES get its deps frontwards (again).
+	* rule.c (set_default_suffixes, convert_to_pattern): Made it read
+	.SUFFIXES's deps frontwards, so the converted rules will not be in
+	reverse order.
+
+	* rule.c (new_pattern_rule): Fixed a bug wherein it would keep
+	searching after it had removed a matching rule and ended up diddling
+	with freed storage.
+
+	* rule.c (freerule): Made it take the given rule off the chain.
+	(new_pattern_rule, count_implicit_rule_limits): Use freerule to
+	remove rules from the chain.
+
+	* vpath.c (construct_vpath_list): Made it return after cleaning out
+	all previous searchpaths when given a nil DIRPATH arg, so it won't
+	go into the construction code and dump core dereferencing a nil
+	pointer.
+
+	* variable.c (patsubst_expand): Fixed a bug which made it not match
+	correctly and sometimes dump core.
+
+Mon Aug  8 16:35:48 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (default_suffix_rules): Made the .texinfo.dvi rule remove
+	the files used in the comparison to determine whether or not a
+	second TeX run is necessary.
+
+	* make.texinfo: Fixed some overfull TeX hboxes.
+
+	* make.texinfo (Implicit: Catalogue of Rules): Fixed a Texinfo error.
+
+	* rule.c (create_pattern_rule): Fixed bug wherein index was not
+	being passed its second arg.

+	* read.c (getline): Merged back into readline.
+
+	* rule.c (default_suffixes, default_suffix_rules,

+	3.00' since it's not going to be called that.
+
+Sat Aug  6 19:51:10 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* commands.c (print_commands): Added this function to print the
+	contents of a `struct commands' for -p.
+	* rule.c (print_rule_data_base): Use above.
+	* file.c (print_file_data_base): Ditto.
+
+	* rule.c (count_implicit_rule_limits, new_pattern_rule,

+	changed `struct rule' and act accordingly.
+	(freerule): Added this function to free all the storage used by a rule.
+
+	* rule.c (pattern_search): Made it grok multiple targets of pattern
+	rules.  The matching is done properly, but at present, only the
+	matching pattern's target is used to give deps and commands.
+
+Fri Aug  5 18:00:29 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (struct rule): Changed name, namelen, and patsuffix members
+	to targets, lens, and suffixes, which are arrays, for multiple targets.
+	(create_pattern_rule): Now takes first arg TARGETS, a nil-terminated
+	array of targets, rather than a single target and patsuffix pointer.
+
+	* read.c (record_files): If it finds an implicit pattern rule, it
+	collects all the targets into an array and passes the whole thing to
+	create_pattern_rule.  If there are non-pattern targets, it is a
+	fatal error.
+
+Tue Aug  2 15:06:38 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (readline): Split backslash-newline checking from reading
+	and buffer-expanding.
+	(getline): Created to do the reading and buffer-expanding formerly
+	done in readline.
+
+	* rule.c (pattern_search): Made it reject nonterminal match-anything
+	rules when a specific rule has matched, rather than rejecting
+	terminal match-anything rules in this case.
+
+	* rule.c (convert_to_pattern): Fixed a bug caused when the change to
+	make it only recognize two-suffix rules whose target suffixes
+	precede their dependency suffixes which made it work in the opposite
+	direction (even worse than it started out).
+
+	* rule.c (pattern_search): Made it reject nonterminal match-anything
+	rules as intermediate targets when searching for both real and
+	intermediate dependencies, rather than only when searching for
+	intermediate ones.
+
+Sun Jul 31 00:33:56 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (convert_to_pattern): Made it only recognize two-suffix
+	rules whose target suffix comes before the dependency suffix in the
+	.SUFFIXES list.
+
+	* variable.c (define_automatic_variables): Made all automatic
+	variables be defined with origin `o_automatic'.
+
+	* variable.h: Added `o_automatic' to `enum variable_origin'
+
+	* file.c (remove_intermediates): Made it not print an error message
+	if the error was that the file does not exist.
+
+	* rule.c: Removed `recursive' member from `struct rule'.
+
+	* remake.c (library_file_mtime): Made it not use the directory hash
+	functions, as reading in and hashing /usr/lib and /lib is slow and
+	most likely unnecessary.
+
+	* remake.c (remake_file): Changed message from ``No specification
+	for making'' to ``No way to make'' so it will be short enough that
+	most filenames will fit on a line.
+	Made it look at the `recursive' member of the `struct commands',
+	rather than of the `struct file' (which no longer has one).
+
+	* commands.c (execute_file_commands): Made it look at the
+	`recursive' member of the `struct commands', rather than of the
+	`struct file' (which no longer has one).
+
+	* file.h: Removed `recursive' member from `struct file'.
+
+	* commands.h: Added `recursive' member to `struct commands'.
+
+	* dep.h: Removed unused `quotedparen' member from `struct nameseq'
+	and `struct dep'.
+
+	* read.c (dequote): Removed this function.
+	(multi_glob): Removed reference to `quotedparen' member of
+	a `struct nameseq' and calls to dequote.
+
+	* read.c (record_files): Made it set the stem for $* for all static
+	pattern rules, not just those with commands given at that time.
+	Removed check for recursive commands.
+	Made it check for pairs of .SUFFIXES dependencies to reject as
+	default goals as well as single ones (that don't start with dots).
+	(read_makefile): Added checks for recursive commands to set
+	the `recursive' flag in the `struct commands'.
+
+Sat Jul 30 15:47:23 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (find_next_token): Made the LENGTHPTR arg optionally nil.
+
+	* make.c: Removed `files_made' variable which is defined static in
+	remake.c and used only there.
+	(main): Cleaned up somewhat.
+	(decode_switches): Cleaned up a bit.  Made an unknown option be a
+	non-fatal error.
+	(decode_env_switches): Made LEN arg unsigned.  Cleaned up.
+	(print_version): Made it say ``see the source'' rather than ``see
+	the source file'', since there is more than one.
+
+	* file.h: Made `num_intermediates' declared unsigned.
+
+	* file.c: Made `num_intermediates' variable unsigned.
+	(remove_intermediates): Removed unused FORMAT arg.
+	(enter_file): Made it handle double-colon files properly, adding the
+	new entry as the old entry's prev pointer.
+
+	* dir.c: Re-indented the `struct dir' definition to be right.
+	(dir_load): Cleaned up slighty.
+	(file_exists_p): Removed comment saying we could use `access', since
+	that is a bad idea (except for setuid programs).  Cleaned up slightly.
+
+	* commands.c: Changed some comments slightly.
+	(execute_file_commands): Cleaned up a bit.  Changed some comments,
+	added others.  Moved freeing of storage for $^ and $? to the same
+	place as for the other automatic variables.
+	(execute_command_line): Made `#' trigger a shell.
+	Added some comments.  Cleaned up a bit.  Put all the special chars
+	that trigger shells into an array easily changeable at the top.
+
+	* ar.c: Added comments explaining each function.
+	(ar_scan_1): Merged into ar_member_date.
+	(ar_member_date): Changed call to ar_scan_1 to the body of that
+	function.
+	(ar_member_date_1): Simplified to a ?: expression rather than an
+	if-else statement.
+	(ar_member_touch): Changed error handling around a bit.
+	None of these errors are fatal now.
+
+	* variable.c (subst_expand): Added a new arg BY_WORD, to do substs
+	only on full words.
+	(patsubst_expand): Fixed bug which made calls whose patterns
+	contained no `%' to not work correctly, by using above.
+	(variable_expand): Pass extra arg to `subst_expand'.
+
+	* variable.c (expand_function): Fixed bug which made `foreach' calls
+	with one-word lists run off into never-never land.
+
+Fri Jul 29 20:12:36 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* variable.c (expand_function): Made a very minor speed improvement
+	by avoiding an unnecessary strlen call.
+
+Wed Jul 27 16:01:47 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (default_suffixes): Rearranged the list somewhat; added
+	`.el' and `.elc' to speed things up (especially when building
+	Emacs), for the same reason `.h' is there.
+
+	* read.c (record_files): Changed `lineno' from `long' to
+	`unsigned int'.
+
+Sun Jul 24 02:15:30 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* variable.c (expand_function): Eliminated use of `wstok'
+	because it is non-reentrant and unreliable.
+	Fixed a minor bug which would cause something not to be freed.
+	* make.c (wstok): Removed `wstok' because it is no longer used.
+
+	* variable.c (expand_function): Made `foreach' function put
+	spaces between output texts like it's supposed to.
+	
+Sat Jul 23 17:32:55 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (default_suffixes, default_suffix_rules): Added rule
+	to make %.dvi from %.texinfo.
+
+	* dir.c (print_dir_data_base): Made it say a bit more.
+
+Fri Jul 22 23:13:16 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (print_data_base): Split this function up into one
+	for each thing.
+	* variable.c (print_variable_data_base): One of the above.
+	* rule.c (print_rule_data_base): Ditto.
+	* file.c (print_file_data_base): Ditto.
+	* dir.c (print_dir_data_base): Ditto.
+
+	* rule.c (install_pattern_rule): Fixed a bug which caused the
+	terminal and recursive flags to always be zero for rules
+	entered by this function.
+
+	* make.texinfo (Rules: Double-colon): Added a paragraph
+	explaining the purpose of double-colon rules.
+
+	* make.texinfo (Implicit: Catalogue of Rules): Updated to
+	reflect new C++, TeX, Web, and Texinfo rules.  Other slight
+	editorial changes.
+
+	* commands.c (execute_file_commands): Fixed a bug wherein
+	random memory could get written for files with no deps.
+	
+Wed Jul 20 19:30:31 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* read.c (readline): Fix bug wherein it would not recognize a
+	backslash-newline if the buffer filled up and was enlarged
+	right before reading the newline.
+	
+Tue Jul 19 19:55:02 1988  Roland McGrath  (mcgrath at chilli.Berkeley.EDU)
+
+	* read.c: Added default suffix rules for .cc (using $(C++),
+	which defaults to `g++', and $(C++FLAGS)), .tex, .dvi, .web
+	and .cweb (using $(TEX), $(WEAVE), $(TANGLE), $(CWEAVE) and
+	$(CTANGLE)).
+	
+Sat Jul 16 21:24:28 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* Made error formats use %u rather than %ld for line numbers,
+	which are now unsigned int's rather than long's.
+
+	* read.c (conditional_line): Fixed some bugs caused by use of
+	unsigned int rather than int in one place.
+
+	* read.c (conditional_line): Put the info about active
+	conditionals in a struct.
+	(read_makefile): Make a new struct of info about conditionals
+	for included makefiles and restore the old one after the
+	included makefile has been read.
+
+	* read.c (read_makefile): Don't try to read a makefile with
+	name "" after giving an error message because an `include'
+	directive gave no filename.
+
+	* read.c (read_makefile): Give an error message for
+	non-whitespace text after the filename in an `include' directive.
+
+	* make.c (error): Take five args, like `fatal'.  It managed to
+	lose with only two.  Is there a better way to do this without vfprintf?
+
+	* read.c (read_makefile): Commands consisting of only
+	whitespace are not the same as no commands.  I thought I'd
+	fixed this bug months ago; it seems to have come back.
+
+	* make.c (collapse_continuations): All whitespace around a
+	backslash-newline combination is turned into a single space.
+
+	* Added COPYING file and copyright notices to all files.
+
+	* make.texinfo (Running: Goals): Fix a typo.
+
+	* read.c (do_define): Take an arg for the origin of the
+	variable being defined.
+	(read_makefile): Grok `override define'.
+
+	* make.texinfo (Variables: Override Directive, Defining):
+	Document the `override define' combination directive.
+
+	* ar.c (ar_member_date): Make a 0 return from `ar_scan' return
+	(time_t) -1 (nonexistent file), rather than (time_t) 0, which,
+	when put in the `struct file', makes `file_mtime' try to get
+	the mtime over and over again.
+
+	* variable.c (pattern_matches): Fix a bug that made patterns
+	not beginning with `%' never match.
+	
+Fri Jul 15 21:01:44 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* Took Make out of RCS.
+
+	* Split the monolithic `make.c' into several smaller files.

+2000-06-22  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (start_job_command): Increment commands_started before the
+	special check for ":" (empty command) to avoid spurious "is up to
+	date" messages.  Also move the test for question_flag after we
+	expand arguments, and only stop if the expansion provided an
+	actual command to run, not just whitespace.  This fixes PR/1780.
+
+2000-06-21  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): If we find a semicolon in the target
+	definition, remember where it was.  If the line turns out to be a
+	target-specific variable, add back the semicolon and everything
+	after it.  Fixes PR/1709.
+
+2000-06-19  Paul D. Smith  <psmith@gnu.org>
+
+	* config.h-vms.template: #define uintmax_t for this system.
+	* config.ami.template: Ditto.
+	* config.h.W32.template: Ditto.
+
+	* configure.in: We don't use select(2) anymore, so don't bother
+	checking for it.
+	* acconfig.h: Ditto.
+	* acinclude.m4: Ditto.
+
+	* file.c (all_secondary): New static global; if 1 it means
+	.SECONDARY with no prerequisites was seen in the makefile.
+	(snap_deps): Set it appropriately.
+	(remove_intermediates): Check it.
+	(num_intermediates): Remove this global, it's not used anywhere.
+	(considered): Move this to remake.c and make it static.
+
+	* NEWS: Document the change to .SECONDARY.
+	* make.texinfo (Special Targets): Document the change to .SECONDARY.
+
+	* implicit.c (pattern_search): Remove the increment of
+	num_intermediates; it's not used.
+	* filedef.h: Remove num_intermediates and considered.
+
+	* function.c (handle_function): If the last argument was empty, we
+	were pretending it didn't exist rather than providing an empty
+	value.  Keep looking until we're past the end, not just at the end.
+
+	* implicit.c (pattern_search): Multi-target implicit rules weren't
+	expanding the "also made" targets correctly if the pattern didn't
+	contain a slash but the target did; in that case the directory
+	part wasn't being added back to the stem on the "also made"
+	targets.  Reported by Seth M LaForge <sethml@newtonlabs.com>, with
+	a patch.
+
+2000-06-17  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* Makefile.DOS.template (DESTDIR, bindir, datadir, libdir)
+	(infodir, mandir, includedir): Support installation under a
+	non-default DESTDIR.
+
+	* remake.c (f_mtime): Fix the spelling of __MSDOS__.
+
+	* configh.DOS.template (HAVE_FDOPEN, HAVE_MKSTEMP): Define.
+
+2000-06-14  Paul D. Smith  <psmith@gnu.org>
+
+	* acinclude.m4 (pds_WITH_GETTEXT): rewrite fp_WITH_GETTEXT and
+	rename it to avoid confusion.  This version is very specific: it
+	won't accept any gettext that isn't GNU.  If the user doesn't
+	explicitly ask for the included gettext, we look to see if the
+	system gettext is GNU (testing both the actual libintl library,
+	and the libintl.h header file).  Only if the system gettext is
+	really GNU gettext will we allow it to be used.
+	(pds_CHECK_SYSTEM_GETTEXT): A helper function.
+
+2000-06-13  Paul D. Smith  <psmith@gnu.org>
+
+	* gettext.h: If we have libintl.h, use that instead of any of the
+	contents of gettext.h.  We won't check for libintl.h unless we're
+	using the system gettext.
+
+	* function.c (func_word): Clarify error message.
+
+2000-06-10  Paul Eggert  <eggert@twinsun.com>
+
+	Support nanosecond resolution on hosts with 64-bit time_t and
+	uintmax_t (e.g. 64-bit Sparc Solaris), by splitting
+	FILE_TIMESTAMP into a 30-bit part for nanoseconds, with the
+	rest for seconds, if FILE_TIMESTAMP is at least 64 bits wide.
+
+	* make.h: Always define FILE_TIMESTAMP to be uintmax_t, for
+	simplicity.
+
+	* filedef.h (FILE_TIMESTAMP_HI_RES, FILE_TIMESTAMP_LO_BITS)
+	(UNKNOWN_MTIME, NONEXISTENT_MTIME, OLD_MTIME)
+	(ORDINARY_MTIME_MIN, ORDINARY_MTIME_MAX): New macros.
+	(FILE_TIMESTAMP_STAT_MODTIME): Now takes fname arg.  All uses changed.
+	(FILE_TIMESTAMP_DIV, FILE_TIMESTAMP_MOD)
+	(FILE_TIMESTAMP_FROM_S_AND_NS): Remove.
+	(FILE_TIMESTAMP_S, FILE_TIMESTAMP_NS): Use shifts instead of
+	multiplication and division.  Offset the timestamps by
+	ORDINARY_MTIME_MIN.
+	(file_timestamp_cons): New decl.
+	(NEW_MTIME): Now just the maximal timestamp value, as we no longer use
+	-1 to refer to nonexistent files.
+
+	* file.c (snap_deps, print_file): Use NONEXISTENT_MTIME,
+	UNKNOWN_MTIME, and OLD_MTIME instead of magic constants.
+	* filedef.h (file_mtime_1): Likewise.
+	* main.c (main): Likewise.
+	* remake.c (update_file_1, notice_finished_file, check_dep)
+	(f_mtime, name_mtime, library_search): Likewise.
+	* vpath.c (selective_vpath_search): Likewise.
+
+	* remake.c (f_mtime): Do not assume that (time_t) -1 equals
+	NONEXISTENT_MTIME.  When futzing with time stamps, adjust by
+	multiples of 2**30, not 10**9.  Do not calculate timestamp
+	adjustments on DOS unless they are needed.
+
+	* commands.c (delete_target): Do not assume that
+	FILE_TIMESTAMP_S yields -1 for a nonexistent file, as that is
+	no longer true with the new representation.
+
+	* file.c (file_timestamp_cons): New function, replacing
+	FILE_TIMESTAMP_FROM_S_AND_NS.  All uses changed.
+	(file_timestamp_now): Use FILE_TIMESTAMP_HI_RES instead of 1 <
+	FILE_TIMESTAMPS_PER_S to determine whether we're using hi-res
+	timestamps.
+	(print_file): Print OLD_MTIME values as "very old" instead of
+	as a timestamp.
+
+2000-05-31  Paul Eggert  <eggert@twinsun.com>
+
+	* remake.c (name_mtime): Check for stat failures.  Retry if EINTR.
+
+2000-05-24  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (decode_switches): The "positive_int" switch uses atoi()
+	which succeeds for any input, and doesn't notice if extra,
+	non-digit text is after the number.  This causes make to mis-parse
+	command lines like "make -j 5foo" as "make -j5" (ignoring "foo"
+	completely) instead of "make -j0 5foo" (where "5foo" is a
+	target).  Fix this by checking the value by hand.  We could use
+	strtol() if we were sure of having it; this is the only
+	questionable use of atoi() I found so we'll just stick with that.
+	Fixes PR/1716.
+
+	* i18n/ja.po, i18n/nl.po, i18n/pt_BR.po: New translation files.
+	* configure.in (ALL_LINGUAS): Added pt_BR.
+
+2000-05-22  Paul Eggert  <eggert@twinsun.com>
+
+	* remake.c (f_mtime): Fix bug when handling future odd
+	timestamps in the WINDOWS32 case.  Do not bother initializing
+	static var to zero.  Simplify code that works around WINDOWS32
+	and __MSDOS__ time skew brain damage.
+
+2000-05-22  Paul Eggert  <eggert@twinsun.com>
+
+	* job.c: Don't include time.h, as make.h already does this.
+
+2000-05-22  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.in (AC_CHECK_HEADERS): Add sys/time.h.
+	(AC_HEADER_TIME): Add.
+	(clock_gettime): Prefer -lrt to -lposix4, for Solaris 7.
+	(gettimeofday): Add check for standard version of gettimeofday.
+	This merges changes written by Paul D. Smith.
+
+	* file.c (file_timestamp_now):  Use gettimeofday if available
+	and if clock_gettime does not work.  Don't bother with
+	high-resolution clocks if file timestamps have only one-second
+	resolution.
+
+	* make.h <sys/time.h>: Include, conditionally on the usual
+	TIME_WITH_SYS_TIME and HAVE_SYS_TIME_H macros.  This is needed
+	for gettimeofday.
+
+2000-05-20  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): We weren't keeping makefile names around
+	unless there was a rule defined in them; but now we need to keep
+	them for variables as well.  Forget trying to be fancy: just keep
+	every makefile name we successfully open.
+
+	* remote-cstms.c (start_remote_job_p): Change DB_EXTRA (?) to DB_JOBS.
+
+2000-05-17  Paul Eggert  <eggert@twinsun.com>
+
+	* commands.c (chop_commands): Ensure ctype macro args are nonnegative.
+	* expand.c (variable_expand_string): Likewise.
+	* function.c (subst_expand, lookup_function, msdos_openpipe):
+	Likewise.
+	* job.c (vms_redirect, start_job_command, new_job, child_execute_job,
+	construct_command_argv_internal, construct_command_argv): Likewise.
+	* main.c (decode_env_switches, quote_for_env): Likewise.
+	* misc.c (collapse_continuations, end_of_token, end_of_token_w32,
+	next_token): Likewise.
+	* read.c (read_makefile, do_define, conditional_line,
+	find_char_unquote,get_next_mword): Likewise.
+	* variable.c (try_variable_definition): Likewise.
+	* vpath.c (construct_vpath_list): Likewise.
+	* w32/pathstuff.c (convert_vpath_to_windows32): Likewise.
+
+2000-05-10  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* main.c (main) [__MSDOS__]: Add SIGFPE to signals we block when
+	running child programs, to prevent Make from dying on Windows 9X
+	when the child triggers an FP exception.
+
+2000-05-08  Paul D. Smith  <psmith@gnu.org>
+
+	* dir.c (find_directory) [WINDOWS32]: If we strip a trailing "\"
+	from the directory name, remember to add it back.  The argument
+	might really be inside a longer string (e.g. %Path%) and if you
+	don't restore the "\" it'll be truncated permanently.  Fixes PR/1722.
+	Reported by <steven@surfcast.com>
+
+2000-05-02  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (construct_command_argv_internal) [WINDOWS32]: Added "rd"
+	and "rmdir" to the list of command.com commands.
+	Reported by Elod Horvath <Elod_Horvath@lnotes5.bankofny.com>
+
+2000-04-24  Paul D. Smith  <psmith@gnu.org>
+
+	* i18n/ja.po: New translation file from the Japanese language team.
+
+2000-04-18  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (f_mtime): If ar_member_date() returns -1 (the member
+	doesn't exist), then return (FILE_TIMESTAMP)-1 rather than
+	returning the timestamp calculated from the value -1.  Fixes PR/1696.
+	Reported by Gilles Bourhis <Gilles.Bourhis@univ-rennes1.fr>.
+
+2000-04-17  Paul D. Smith  <psmith@gnu.org>
+
+	* config.h.W32.template: Add LOCALEDIR macro resolving to "".
+	* w32/subproc/sub_proc.c (process_begin): Remove reference to
+	debug_flag; change it to a DB() call.  Fixes PR/1700.
+	Reported by Jim Smith <jwksmith@attglobal.net>
+
+2000-04-17  Bruno Haible  <haible@clisp.cons.org>
+
+	* arscan.c [BeOS]: Add replacement for nonexistent <ar.h> from GNU
+	binutils.
+
+2000-04-11  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (expand_builtin_function): If no arguments were
+	provided, just quit early rather than changing each function to
+	test for this.
+	(function_table[]): Change the min # of arguments to 0 for all
+	those functions for which it makes sense (currently everything
+	that used to take a minimum of 1 argument, except $(call ...)).
+	Fixes PR/1689.
+
+2000-04-09  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* README.DOS: Add instructions to install a binary distro.
+	Mention latest versions of Windows.
+
+2000-04-07  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* main.c (main): Rename TMP_TEMPLATE into DEFAULT_TMPDIR, and use
+	it for the directory of the temporary file.  If P_tmpdir is
+	defined, use it in preference to "/tmp/".  Try $TMPDIR, $TEMP, and
+	$TMP in the environment before defaulting to DEFAULT_TMPDIR.
+	(print_version): Add year 2000 to the Copyright line.
+
+2000-04-04  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.79 released.
+
+	* make.texinfo: Update documentation with new features for 3.79.
+
+	* function.c (func_wordlist): Don't re-order arguments to
+	wordlist.
+
+2000-04-03  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (f_mtime): Archive member timestamps are stored as
+	time_t, without nanoseconds.  But, f_mtime() wants to return
+	nanosecond info on those systems that support it.  So, convert the
+	return value of ar_member_date() into a FILE_TIMESTAMP, using 0 as
+	the nanoseconds.
+
+2000-03-28  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.78.92 released.
+
+	* build.template: Updates for gettext support; some bugs fixed.
+
+2000-03-27  Paul D. Smith  <psmith@gnu.org>
+
+	* config.guess, config.sub: Updated from config CVS archive at
+	:pserver:anoncvs@subversions.gnu.org:/home/cvs as of today.
+
+	* read.c (record_files): Check if expanding a static pattern
+	rule's prerequisite pattern leaves an empty string as the
+	prerequisite, and issue an error if so.  Fixes PR/1670.
+	(read_makefile): Store the starting linenumber for a rule in
+	TGTS_STARTED.
+	(record_waiting_files): Use the TGTS_STARTED value for the file
+	location passed to record_file() instead of the current
+	linenumber, so error messages list the line where the target was
+	defined instead of the line after the end of the rule definition.
+
+	* remake.c (start_updating, finish_updating, is_updating): Fix
+	PR/1671; circular dependencies in double-colon rules are not
+	diagnosed.  These macros set the updating flag in the root
+	double-colon file instead of the current one, if it's part of a
+	double-colon list.  This solution provided by Tim Magill
+	<magill@gate.net>; I just changed the macro names :).
+	(update_file_1): Call them.
+	(check_dep): Call them.
+
+	The change to not automatically evaluate the $(call ...)
+	function's arguments breaks recursive use of call.  Although using
+	$(if ...) and $(foreach ...) in $(call ...) macros is important,
+	the error conditions generated are simply to obscure for me to
+	feel comfortable with.  If a method is devised to get both
+	working, we'll revisit.  For now, remove this change.
+
+	* function.c (function_table): Turn on the expand bit for func_call.
+	(func_call): Don't expand arguments for builtin functions; that
+	will have already been done.
+
+2000-03-26  Paul D. Smith  <psmith@gnu.org>
+
+	* file.c (remove_intermediates): Never remove targets explicitly
+	requested on the command-line by checking the cmd_target flag.
+	Fixed PR/1669.
+
+2000-03-23  Paul Eggert  <eggert@twinsun.com>
+
+	* filedef.h (FILE_TIMESTAMP_STAT_MODTIME): Use st_mtime instead of
+	st_mtim.tv_sec; the latter doesn't work on Unixware.
+
+2000-03-18  Paul D. Smith  <psmith@gnu.org>
+
+	* file.c (file_hash_enter): If we're trying to change a file into
+	itself, just return.  We used to assert this wasn't true, but
+	someone came up with a weird case involving archives.  After
+	playing with it for a while I decided it was OK to ignore it.
+
+	* default.c: Define COFLAGS to empty to avoid spurious warnings.
+
+	* filedef.h: Change #if ST_MTIM_NSEC to #ifdef; this is a macro

+2000-03-08  Tim Magill  <magill@gate.net>
+
+	* remake.c (update_file): Return the exit status of the pruned
+	file when pruning, not just 0.  Fixes PR/1634.
+
+2000-02-24  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Close a minor potential security hole; if you're
+	reading makefiles from stdin (who does that?) you could run into a
+	race condition with the temp file using mktemp() or tmpnam().  Add
+	a check for mkstemp() and fdopen().
+	* main.c (open_tmpfile): New function to open a temporary file.
+	If we have mkstemp() (and fdopen()), use that.  If not use
+	mktemp() or tmpnam().  If we have fdopen(), use open() to open the
+	file O_CREAT|O_EXCL.  If not, fall back to normal fopen() (insecure).
+	(main): Call it.
+	* job.c (child_execute_job) [VMS]: Call it.
+
+	* variable.c (lookup_variable): If we find a variable which is
+	being expanded, then note it but keep looking through the rest of
+	the set list to see if we can find one that isn't.  If we do,
+	return that.  If we don't, return the original.  Fix for PR/1610.
+
+	While implementing this I realized that it also solves PR/1380 in
+	a much more elegant way.  I don't know what I was smoking before.
+	So, remove the hackage surrounding the original fix for that (see
+	below).  Change this function back to lookup_variable and remove
+	the extra setlist argument.
+	* variable.h (recursively_expand_setlist): Remove the macro,
+	rename the prototype, and remove the extra setlist argument.
+	(lookup_variable): Ditto.
+	* expand.c (recursively_expand): Rename and remove the extra
+	setlist argument.
+	(reference_variable): Use lookup_variable() again.
+	(allocated_variable_append): Remove the extra setlist argument.

+
+	* Version 3.78.91 released.
+
+2000-02-07  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): Reset *p2 to ':', not *colonp.  If any
+	filenames contained backslashes the resulting output (without
+	backslashes) will be shorter, so setting *colonp doesn't change
+	the right character.  Fix for PR/1586.
+
+	For += target-specific variables we need to remember which
+	variable set we found the variable in, so we can start looking
+	from there in the next iteration (otherwise we might see it again
+	in recursively_expand and fail!).  This is turning into a hack; if
+	it gets any worse we'll have to rethink this entire algorithm...
+	implementing expansion of these references separately from the
+	"normal" expansion, say, instead of using the same codepath.
+	Actually, it's already "worse enough" :-/.
+	Fix for PR/1380.
+
+	* variable.h (recursively_expand_setlist): Rename
+	recursively_expand to add a struct variable_set_list argument, and
+	make a macro for recursively_expand.
+	(lookup_variable_setlist): Rename lookup_variable to add a struct
+	variable_set_list argument, and make a macro for lookup_variable.
+
+	* expand.c (recursively_expand_setlist): Take an extra struct
+	variable_set_list argument and pass it to allocated_variable_append().
+	(reference_variable): Use lookup_variable_setlist() and pass the
+	returned variable_set_list to recursively_expand_setlist.
+	(allocated_variable_append): Take an extra setlist argument and
+	use this as the starting place when searching for the appended
+	expansion.  If it's null, use current_variable_set_list as before.
+
+	* variable.c (lookup_variable_setlist): If the LISTP argument is
+	not nil, set it to the list containing the variable we found.

+	* read.c (read_makefile): Keep variable definition location info.
+	(do_define): Ditto.
+	(record_target_var): Ditto.
+	* variable.h (define_variable_in_set): New fileinfo argument.
+	(define_variable, define_variable_loc, define_variable_for_file):
+	Declare new macros.
+
+	Fix PR/1407:
+
+	* filedef.h (struct file): Rename patvar to pat_variables and make
+	it just a variable_set_list; we need our own copy of the pattern
+	variable's variable set list here to avoid overwriting the global
+	one.
+	* variable.c (initialize_file_variables): Move the instantiation
+	of the pat_variables pointer here.  Only do the search after we're
+	done reading the makefiles so we don't search too early.  If
+	there's a pat_variables value, set up the variables next ptr.
+	* expand.c (variable_expand_for_file): Remove the setup of the
+	pat_variables info; it's done earlier now to ensure the parent's
+	pattern variables are set up correctly as well.

+	* vmsfunctions.c (strcmpi): Remove duplicate definition of strcmpi().
+	(readdir): Use DB() instead of testing debug_flag.
+	* dir.c (file_impossible) [VMS]: Search "p" not "name".

+
+	* main.c (decode_debug_flags): If debug_flag is set, enable all

+	(debug_flag): Resurrect this flag variable.
+	(switches): Make -d give the old behavior of turning on all
+	debugging.  Change --debug alone to emit basic debugging and take
+	optional arguments to expand debugging.
+	* NEWS: Document the new debugging options.
+
+	* remake.c (no_rule_error): Remove this function.  This tries to
+	fix a real problem--see the description with the introduction of
+	this function below.  However, the cure is worse than the disease
+	and this approach won't work.
+	(remake_file): Put the code from no_rule_error back here.
+	(update_file_1): Remove call to no_rule_error.
+
+	* filedef.h (struct file): Remove mfile_status field.
+
+2000-01-22  Paul D. Smith  <psmith@gnu.org>
+
+	Integrate GNU gettext support.
+
+	* configure.in: Add AM_GNU_GETTEXT.
+	* Makefile.am: Add options for setting LOCALEDIR, -Iintl, etc.
+	* acinclude.m4: Add gettext autoconf macros.
+	* acconfig.h: Add new gettext #defines.
+	* make.h: Include libintl.h.  Make sure _() and N_() macros are
+	declared.  Make gettext() an empty macro is NLS is disabled.
+	* main.c (struct command_switch switches[]): Can't initialize
+	static data with _() (gettext calls), so use N_() there then use
+	gettext() directly when printing the strings.
+	* remake.c (no_rule_error): The string constants can't be static
+	when initializing _() macros.
+	* file.c (print_file): Reformat a few strings to work better for
+	translation.
+	* po/POTFILES.in, po/Makefile.in.in: New files.  Take

+	Resolve PR/xxxx: don't automatically evaluate the $(call ...)
+	function's arguments.  While we're here, clean up argument passing
+	protocol to always use simple nul-terminated strings, instead of
+	sometimes using offset pointers to mark the end of arguments.
+	This change also fixes PR/1517.
+	Reported by Damien GIBOU <damien.gibou@st.com>.
+
+	* function.c (struct function_table_entry): Remove the negative
+	required_args hack; put in explicit min and max # of arguments.
+	(function_table): Add in the max value.  Turn off the expand bit
+	for func_call.
+	(expand_builtin_function): Test against minimum_args instead of
+	the obsolete required_args.
+	(handle_function): Rewrite this.  We don't try to be fancy and
+	pass one style of arguments to expanded functions and another
+	style to non-expanded functions: pass pointers to nul-terminated
+	strings to all functions.
+	(func_call): Rewrite this.  If we are invoking a builtin function
+	and it's supposed to have its arguments expanded, do that (since
+	it's not done by handle_function for $(call ...) anymore).  For
+	non-builtins, just add the variables as before but mark them as
+	recursive so they'll be expanded later, as needed.
+	(func_if): All arguments are vanilla nul-terminated strings:
+	remove trickery with "argv[1]-1".
+	(func_foreach): Ditto.
+
+	* expand.c (expand_argument): If the second arg is NULL, expand
+	the entire first argument.
+
+	* job.c (new_job): Zero the child struct.  This change was just
+	made to keep some heap checking software happy, not because there
+	was an actual bug (the important memory was being cleared properly).
+
+1999-12-15  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (print_variable): Print the variable with += if the
+	append flag is set.
+
+	* implicit.c (pattern_search): Remove the extra check of the
+	implicit flag added on 8/24/1998.  This causes problems and the
+	reason for the change was better resolved by the change made to
+	check_deps() on 1998-08-26.  This fixes PR/1423.

+	Fix += when used in a target-specific variable context.
+
+	* variable.h: New bitfield APPEND set if we have a +=
+	target-specific variable.
+
+	* variable.c (try_variable_definition): Add an argument to specify
+	if we're trying a target-specific variable.  If we are and it's an
+	append style, don't append it, record it as normal recursive, but
+	set the APPEND flag so it'll be expanded later.
+	* main.c (handle_non_switch_argument): Use new
+	try_variable_definition() signature.
+	* read.c (read_makefile,record_target_var): Ditto.
+
+	* expand.c (allocated_variable_append): New function: like
+	allocated_variable_expand(), but we expand the same variable name

+
+	* make.texinfo (Make Errors): Document the hint about 8 spaces
+	instead of a TAB.
+	(Call Function, Quick Reference): Use @code{$(1)}, not @var.
+
+	* main.c (main) [__MSDOS__]: Say "on this platform" instead of "on

+1999-09-03  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (notice_finished_file): Always set mtime_before_update
+	if it's not been set, not just if we ran some rules.  Otherwise we
+	may have a situation where a target's prerequisite was rebuilt but
+	not changed, so this target's rules weren't run, then
+	update_goal_chain() sees mtime_before_update != last_mtime and
+	thinks that the top-level target changed when it really didn't.
+	This can cause an infinite loop when remaking makefiles.
+	(update_goal_chain): If we get back to the top and we don't know
+	what the goal's last_mtime was, find it now.  We need to know so
+	we can compare it to mtime_before_update later (this is only
+	crucial when remaking makefiles--should we only do it then?)
+
+1999-09-02  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): If "override" appears as the first
+	prerequisite, look further to ensure this is really a
+	target-specific variable definition, and not just some
+	prerequisite named "override".
+
+1999-09-01  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (IS_PATHSEP) [WINDOWS32]: Allow backslash separators
+	for W32 platforms.
+	* read.c (record_files) [WINDOWS32]: Allow backslash separators
+	for W32 platforms.
+	* implicit.c (pattern_search) [WINDOWS32]: Allow backslash
+	separators for W32 platforms.
+
+	* configure.in (MAKE_HOST): Define it to be the canonical build
+	host info, now that we need AC_CANONICAL_HOST anyway (for large
+	file support).
+	* version.c (make_host): Define a variable to MAKE_HOST so we're
+	sure to get it from the local config.h.
+	* main.c (print_version): Use it in the version information.
+	* config.ami.template: Add MAKE_HOST.
+	* configh.dos.template: Ditto.
+	* config.h.W32.template: Ditto.
+	* config.h-vms.template: Ditto.
+
+	* main.c (main): Close the jobserver file descriptors if we need
+	to re-exec ourselves.
+	Also print more reasonable error if users force -jN for submakes.
+	This may be common for a while until people use the jobserver
+	feature.  If it happens, we ignore the existing jobserver stuff
+	and use whatever they specified on the commandline.
+	(define_makeflags): Fixed a long-standing bug: if a long name
+	only option comes immediately after a single letter option with no
+	argument, then the option string is constructed incorrectly.  For
+	example, with -w and --jobserver-fds you get "-w-jobserver-fds..."
+	instead of "-w --jobserver-fds..."; add in an extra " -".
+
+	* make.texinfo (Phony Targets): Add another example of using
+	.PHONY with subdirectories/recursive make.
+
+1999-08-30  Paul D. Smith  <psmith@gnu.org>
+
+	* README.W32.template: Renamed from README.W32 so it's
+	autogenerated during the dist.  A few minor modifications.
+
+	* configure.in: Check for kstat_open before AC_FUNC_GETLOADAVG
+	since the latter needs to know whether the former exists to give
+	an accurate result.
+
+1999-08-26  Rob Tulloh  <rob_tulloh@dev.tivoli.com>
+
+	* NMakefile [WINDOWS32]: Now more robust. If you change a file
+	under w32/subproc, the make.exe will be relinked. Also added some
+	tests to make sure erase commands won't fail when executed in a
+	pristine build environment.
+
+	* w32/subproc/sub_proc.c [WINDOWS32]: Added support for
+	HAVE_CYGWIN_SHELL. If you are using the Cygwin B20.1 release, it
+	is now possible to have have native support for this shell without
+	having to rely on klutzy BATCH_MODE_ONLY_SHELL.
+
+	* config.h.W32 [WINDOWS32]: Added HAVE_CYGWIN_SHELL macro which
+	users can define if they want to build make to use this shell.
+
+	* README.W32 [WINDOWS32]: Added informaton about
+	HAVE_CYGWIN_SHELL. Cleaned up text a bit to make it more current.

+	* main.c (decode_switches): Use it.
+	* function.c (is_numeric): Use it.
+
+	* main.c (struct command_switch): Store the switch char in an

+	Besides, it _is_ always unsigned.
+
+1999-08-24  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo: Change "dependency" to "prerequisite" and

+	* file.c: Change debugging and error messages to use
+	"prerequisite" instead of "dependency".
+	* implicit.c: Ditto.

+	* NEWS: Document it.
+
+1999-08-23  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (update_file): Move the considered check into the
+	double-colon rule loop, so we consider double-colon rules
+	individually (otherwise after the first is pruned, the rest won't
+	get run).
+
+	* README.template: Minor changes.
+
+	Remove the debugging features of the jobserver, so it no longer
+	writes distinct tokens to the pipe.  Thus, we don't need to store
+	the token we get.  A side effect of this is to remove a potential
+	"unavailable token" situation: make-1 invokes make-2 with its
+	special token and make-3 with a normal token; make-2 completes.
+	Now we're waiting for make-3 but using 2 tokens; our special token
+	is idle.  In the new version we don't have special tokens per se,
+	we merely decide if we already have a child or not.  If we don't,
+	we don't need a token.  If we do, we have to get one to run the
+	next child.  Similar for putting tokens back: if we're cleaning up
+	the last child, we don't put a token back.  Otherwise, we do.
+
+	* main.c: Add a new, internal flag --jobserver-fds instead of
+	overloading the meaning of -j.  Remove job_slots_str and add the
+	stringlist jobserver_fds.
+	(struct command_switch): We don't need the int_string type.
+	(switches[]): Add a new option for --jobserver-fds and remove
+	conditions around -j.  Make the description for the former 0 so it
+	doesn't print during "make --help".
+	(main): Rework jobserver parsing.  If we got --jobserver-fds
+	make sure it's valid.  We only get one and job_slots must be 0.
+	If we're the toplevel make (-jN without --jobserver-fds) create
+	the pipe and write generic tokens.
+	Create the stringlist struct for the submakes.
+	Clean up the stringlist where necessary.
+	(init_switches): Remove int_string handling.
+	(print_usage): Don't print internal flags (description ptr is 0).
+	(decode_switches): Remove int_string handling.
+	(define_makeflags): Remove int_string handling.
+
+	* job.c: Remove my_job_token flag and all references to the
+	child->job_token field.
+	(free_job_token): Remove this and merge it into free_child().
+	(reap_children): Rework the "reaped a child" logic slightly.
+	Don't call defunct free_job_token anymore.  Always call
+	free_child, even if we're dying.
+	(free_child): If we're not freeing the only child, put a token
+	back in the pipe.  Then, if we're dying, don't bother to free.
+	(new_job): If we are using the jobserver, loop checking to see if
+	a) there are no children or b) we get a token from the pipe.
+
+	* job.h (struct child): Remove the job_token field.
+
+1999-08-20  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (try_variable_definition): Allocate for variable
+	expansion in f_append with a simple variable: if we're looking at
+	target-specific variables we don't want to trash the buffer.
+	Noticed by Reiner Beninga <Reiner.Beninga@mchp.siemens.de>.
+
+1999-08-16  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* main.c (main) [__MSDOS__]: Mirror any backslashes in argv[0], to

+	characters.
+
+1999-08-16  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.77.93 released.
+
+1999-08-13  Paul D. Smith  <psmith@gnu.org
+
+	* function.c (func_if): New function $(if ...) based on the
+	original by Han-Wen but reworked quite a bit.
+	(function_table): Add it.
+	* NEWS: Introduce it.
+	* make.texinfo (If Function): Document it.
+
+	* job.c (free_job_token): Check for EINTR when writing tokens to
+	the jobserver pipe.
+
+1999-08-12  Paul D. Smith  <psmith@gnu.org>
+
+	Another jobserver algorithm change.  We conveniently forgot that
+	the blocking bit is shared by all users of the pipe, it's not a
+	per-process setting.  Since we have many make processes all
+	sharing the pipe we can't use the blocking bit as a signal handler
+	flag.  Instead, we'll dup the pipe's read FD and have the SIGCHLD
+	handler close the dup'd FD.  This will cause the read() to fail
+	with EBADF the next time we invoke it, so we know we need to reap
+	children.  We then re-dup and reap.
+
+	* main.c (main): Define the job_rfd variable to hold the dup'd FD.
+	Actually dup the read side of the pipe.  Don't bother setting the
+	blocking bit on the file descriptor.
+	* make.h: Declare the job_rfd variable.
+	* job.c (child_handler): If the dup'd jobserver pipe is open,
+	close it and assign -1 to job_rfd to notify the main program that
+	we got a SIGCHLD.
+	(start_job_command): Close the dup'd FD before exec'ing children.
+	Since we open and close this thing so often it doesn't seem
+	worth it to use the close-on-exec bit.
+	(new_job): Remove code for testing/setting the blocking bit.
+	Instead of EAGAIN, test for EBADF.  If the dup'd FD has been
+	closed, re-dup it before we reap children.
+
+	* function.c (func_shell): Be a little more accurate about the
+	length of the error string to allocate.
+
+	* expand.c (variable_expand_for_file): If there's no filenm info
+	(say, from a builtin command) then reset reading_file to 0.
+
+1999-08-09  Paul D. Smith  <psmith@gnu.org>
+
+	* maintMakefile: Use g in sed (s///g) to replace >1 variable per

+
+	* Makefile.DOS.template [__MSDOS__]: Fix mostlyclean-aminfo to
+	remove the right files.
+
+1999-08-01  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* function.c (msdos_openpipe) [__MSDOS__]: *Really* return a FILE
+	ptr.
+
+1999-08-01  Paul D. Smith  <psmith@gnu.org>
+
+	New jobserver algorithm to avoid a possible hole where we could
+	miss SIGCHLDs and get into a deadlock.  The original algorithm was
+	suggested by Roland McGrath with a nice refinement by Paul Eggert.
+	Many thanks as well to Tim Magill and Howard Chu, who also
+	provided many viable ideas and critiques.  We all had a fun week
+	dreaming up interesting ways to use and abuse UNIX syscalls :).
+
+	Previously we could miss a SIGCHLD if it happened after we reaped
+	the children but before we re-entered the blocking read.  If this
+	happened to all makes and/or all children, make would never wake
+	up.
+
+	We avoid this by having the SIGCHLD handler reset the blocking bit
+	on the jobserver pipe read FD (normally read does block in this
+	algorithm).  Now if the handler is called between the time we reap
+	and the time we read(), and there are no tokens available, the
+	read will merely return with EAGAIN instead of blocking.
+
+	* main.c (main): Set the blocking bit explicitly here.
+	* job.c (child_handler): If we have a jobserver pipe, set the
+	non-blocking bit for it.
+	(start_waiting_job): Move the token stuff back to new_job; if we
+	do it here then we're not controlling the number of remote jobs
+	started!
+	(new_job): Move the check for job slots to _after_ we've created a
+	child structure.  If the read returns without getting a token, set
+	the blocking bit then try to reap_children.
+
+	* make.h (EINTR_SET): Define to test errno if EINTR is available,
+	or 0 otherwise.  Just some code cleanup.
+	* arscan.c (ar_member_touch): Use it.
+	* function.c (func_shell): Use it.
+	* job.c (reap_children): Use it.
+	* remake.c (touch_file): Use it.
+
+1999-07-28  Paul D. Smith  <psmith@gnu.org>
+

+	NLS support.
+	* <all>: Add _()/N_() around translatable strings.
+
+1999-07-27  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c: Make sure make.h comes before other headers.
+
+1999-07-26  Paul D. Smith  <psmith@gnu.org>
+

+
+1999-07-25  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* remake.c [__MSDOS__]: Don't include variables.h, it's already
+	included.
+
+	* function.c (msdos_openpipe) [__MSDOS__]: Return FILE ptr.
+	(func_shell) [__MSDOS__]: Fix the argument list.
+
+	* Makefile.DOS.template: Update from Makefile.in.
+
+	* README.DOS.template: Configure command fixed.
+
+	* configh.dos.template: Update to provide definitions for
+	uintmax_t, fd_set_size_t, and HAVE_SELECT.
+
+1999-07-24  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.77.91 released.
+
+	* configure.in: Changes to the boostrapping code: if build.sh.in
+	doesn't exist configure spits an error and generates an empty
+	build.sh file which causes make to be confused.
+	* maintMakefile: Don't build README early.
+
+1999-07-23  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (my_job_token): This variable controls whether we've
+	handed our personal token to a subprocess or not.  Note we could
+	probably infer this from the value of job_slots_used, but it's
+	clearer to just keep it separately.  Job_slots_used isn't really
+	relevant when running the job server.
+	(free_job_token): New function: free a job token.  If we don't
+	have one, no-op.  If we have the personal token, reclaim it.  If
+	we have another token, write it back to the pipe.
+	(reap_children): Call free_job_token.
+	(free_child): Call free_job_token.
+	(start_job_command): Remove duplicate test for '+' in the command.
+	If we don't appear to be running a recursive make, close the
+	jobserver filedescriptors.
+	(start_waiting_job): If our personal token is available, use that
+	instead of going to the server pipe.
+	(*): Add the token value to many debugging statements, and print
+	the child target name in addition to the ptr hex value.
+	Change the default "no token" value from '\0' to '-' so it looks
+	better in the output.
+
+	* main.c (main): Install the child_handler with sigaction()
+	instead of signal() if we have it.  On SysV systems, signal() uses
+	SysV semantics which are a pain.  But sigaction() always does what
+	we want.
+	(main): If we got job server FDs from the environment, test them
+	to see if they're open.  If not, the parent make closed them
+	because it didn't think we were a submake.  Print a warning and
+	suggestion to use "+" on the submake invocation, and hard-set to
+	-j1 for this instance of make.
+	(main): Change the algorithm for assigning slots to be more
+	robust.  Previously make checked to see if it thought a subprocess
+	was a submake and if so, didn't give it a token.  Since make's
+	don't consume tokens we could spawn many of makes fighting for a
+	small number of tokens.  Plus this is unreliable because submakes
+	might not be recognized by the parent (see above) then all the
+	tokens could be used up by unrecognized makes, and no one could
+	run.  Now every make consumes a token from its parent.  However,
+	the make can also use this token to spawn a child.  If the make
+	wants more than one, it goes to the jobserver pipe.  Thus there
+	will never be more than N makes running for -jN, and N*2 processes
+	(N makes and their N children).  Every make can always run at
+	least one job, and we'll never deadlock.  (Note the closing of the
+	pipe for non-submakes also solves this, but this is still a better
+	algorithm.)  So!  Only put N-1 tokens into the pipe, since the
+	topmost make keeps one for itself.
+
+	* configure.in: Find sigaction.  Disable job server support unless
+	the system provides it, in addition to either waitpid() or
+	wait3().
+
+1999-07-22  Rob Tulloh  <rob_tulloh@dev.tivoli.com>
+
+	* arscan.c (ar_member_touch) [WINDOWS32]: The ar_date field is a

+
+1999-07-21  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.77.90 released.
+
+	* Makefile.am (AUTOMAKE_OPTIONS): Require automake 1.4.
+
+	* function.c: Rearrange so we don't need to predeclare the
+	function_table array; K&R C compilers don't like that.
+
+	* acinclude.m4 (AC_FUNC_SELECT): Ouch; this requires an ANSI C
+	compiler!  Change to work with K&R compilers as well.
+
+	* configure.in (AC_OUTPUT): Put build.sh back.  I don't know how I
+	thought it would work this way :-/.  We'll have to think of
+	something else.
+	* Makefile.am: Remove rule to create build.sh.
+
+	* default.c (default_suffix_rules): Rearrange the default command
+	lines to conform to POSIX rules (put the filename argument $<
+	_after_ the OUTPUT_OPTION, not before it).
+
+	* various: Changed !strncmp() calls to strneq() macros.
+
+	* misc.c (sindex): Make slightly more efficient.

+	* vpath.c (construct_vpath_list): Ditto.
+
+	* misc.c (xrealloc): Some reallocs are non-standard: work around
+	them in xrealloc by calling malloc if PTR is NULL.
+	* main.c (main): Call xrealloc() directly instead of testing for
+	NULL.
+
+	* function.c (func_sort): Don't try to free NULL; some older,
+	non-standard versions of free() don't like it.
+
+	* configure.in (--enable-dmalloc): Install some support for using
+	dmalloc (http://www.dmalloc.com/) with make.  Use --enable-dmalloc
+	with configure to enable it.
+
+	* function.c (function_table_entry): Whoops!  The function.c
+	rewrite breaks backward compatibility: all text to a function is
+	broken into arguments, and extras are ignored.  So $(sort a,b,c)
+	returns "a"!  Etc.  Ouch.  Fix it by making a positive value in
+	the REQUIRED_ARGS field mean exactly that many arguments to the
+	function; any "extras" are considered part of the last argument as
+	before.  A negative value means at least that many, but may be
+	more: in this case all text is broken on commas.
+	(handle_function): Stop when we've seen REQUIRED_ARGS args, if >0.
+	(expand_builtin_function): Compare number of args to the absolute
+	value of REQUIRED_ARGS.
+
+1999-07-20  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (start_job_command): Ensure that the state of the target
+	is cs_running.  It might not be if we skipped all the lines due to
+	-n (for example).
+
+	* commands.c (execute_file_commands): If we discover that the
+	command script is empty and succeed early, set cs_running so the
+	modtime of the target is still rechecked.
+
+	* rule.c (freerule): Free the dependency list for the rule.
+
+	* implicit.c (pattern_search): When turning an intermediate file
+	into a real target, keep the also_make list.
+	Free the dep->name if we didn't use it during enter_file().
+
+1999-07-16  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): Don't allocate the commands buffer until
+	we're sure we found a makefile and won't return early (mem leak).
+
+	* job.c (start_job_command): Broken #ifdef test: look for F_SETFD,
+	not FD_SETFD.  Close-on-exec isn't getting set on the bad_stdin

+	* getloadavg.c (getloadavg): Ditto.
+
+1999-07-15  Paul D. Smith  <psmith@gnu.org>

+
+1999-07-09  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (start_waiting_job): Don't get a second job token if we
+	already have one; if we're waiting on the load to go down
+	start_waiting_job() might get called twice on the same file.
+
+	* filedef.h (struct file): Add new field, mtime_before_update.
+	When notice_finished_file runs it assigns the cached last_mtime to
+	this field.
+	* remake.c (update_goal_chain): Notice that a file wasn't updated
+	by asking if it changed (g->changed) and comparing the current
+	cached time (last_mtime) with the previous one, stored in
+	mtime_before_update.  The previous check ("did last_mtime changed
+	during the run of update_file?") fails for parallel builds because
+	last_mtime is set during reap_children, before update_file is run.
+	This causes update_goal_chain to always return -1 (nothing
+	rebuilt) when running parallel (-jN).  This is OK during "normal"
+	builds since our caller (main) treats these cases identically in
+	that case, but if when rebuilding makefiles the difference is very
+	important, as it controls whether we re-exec or not.
+	* file.c (file_hash_enter): Copy the mtime_before_update field.
+	(snap_deps): Initialize mtime_before_update to -1.
+	* main.c (main): Initialize mtime_before_update on old (-o) and
+	new (-W) files.
+
+1999-07-08  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (switches): Define a new switch -R (or
+	--no-builtin-variables).  This option disables the defining of all
+	the GNU make builtin variables.
+	(main): If -R was given, force -r as well.
+	* default.c (define_default_variables): Test the new flag.
+	* make.h: Declare global flag.
+	* make.texinfo (Options Summary): Document the new option.
+	(Implicit Variables): Ditto.
+
+1999-07-06  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo (Options Summary): Correct examples in
+	--print-data-base option summary (problem reported by David Morse
+	<morse@nichimen.com>).
+
+	* arscan.c: Add support for archives in Windows (VC++).  Frank
+	Libbrecht <frankl@abzx.belgium.hp.com> provided info on how to do
+	this.
+	* NMakefile.template (CFLAGS_any): Remove NO_ARCHIVES from the
+	compile line.
+	* build_w32.bat: Ditto.
+
+	* remake.c (no_rule_error): Fix -include/sinclude so it doesn't
+	give errors if you try to -include the same file twice.
+	(updating_makefiles): New variable: we need to know this info in
+	no_rule_error() so we know whether to print an error or not.
+	(update_file_1): Unconditionally call no_rule_error(), don't try
+	to play games with the dontcare flag.
+
+1999-06-14  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo (Remaking Makefiles): Add a description of how to
+	prevent implicit rule searches for makefiles.
+
+	* make.1: Remove statement that make continues processing when -v
+	is given.
+
+1999-06-14  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): Cast -1 arguments to
+	variable_expand_string() to long.  Alexandre Sauve
+	<Alexandre.SAUVE@ifp.fr> reports that without casts, this breaks
+	on a NEC SUPER-UX SX-4 system (and it's wrong without a cast
+	anyway).  Of course, (a) I'd really love to start using function
+	prototypes, and (b) there's a whole slew of issues related to int
+	vs. long and signed vs. unsigned in the length handling of
+	variable buffers, etc.  Gross.  Needs a complete mucking-out.
+	* expand.c (variable_expand): Ditto.
+
+	* acinclude.m4 (AC_FUNC_SELECT): Slight enhancement for AIX 3.2 by
+	Lars Hecking <lhecking@nmrc.ucc.ie>.
+
+	* read.c (get_next_mword): Allow colons to be escaped in target
+	names: fix for regression failure.
+
+1999-04-26  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (main): Reset read_makefiles to empty after processing so
+	we get the right error message.
+
+1999-04-25  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo: Updates to @dircategory and @direntry suggested by
+	Karl Berry <karl@cs.umb.edu>.
+
+1999-04-23  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* job.c (start_job_command) [__MSDOS__]: Call unblock_sigs before
+	turning off dos_command_running, so child's signals produce the
+	right effect.
+
+	* commands.c (fatal_error_signal) [__MSDOS__]: Use EXIT_FAILURE
+	instead of 1.
+
+1999-04-18  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* configh.dos.template: Update to recognize that version 2.02 of
+	DJGPP contains sys_siglist stuff.
+
+1999-04-14  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo (Options/Recursion): Document the job server.
+	(Parallel): Tweaks.
+
+1999-04-13  Paul D. Smith  <psmith@gnu.org>
+
+	Implement a new "job server" feature; the implementation was
+	suggested by Howard Chu <hyc@highlandsun.com>.
+
+	* configure.in (job-server): New disable option for job server
+	support--it's enabled by default.  If it works well this will go
+	away.
+
+	* NEWS: Summarize the new feature.
+
+	* acconfig.h: New definition MAKE_JOBSERVER if job server support
+	is enabled.
+	* config.h-vms.template: Undef MAKE_JOBSERVER for this port.
+	* config.h.W32.template: Ditto.
+	* config.ami.template: Ditto.
+
+	* main.c (struct command_switch): Add a new type: int_string.
+	(switches[]) Use int_string for -j if MAKE_JOBSERVER.
+	(init_switches): Initialize the new int_string switch type.
+	(print_usage): New function, extracted from decode_switches().
+	(decode_switches): Call it.  Decode the new int_string switch type.
+	(define_makeflags): Add new int_string switch data to MAKEFLAGS.
+	(job_fds[]) Array to contain the pipe file descriptors.
+	(main): Parse the job_slots_str option results.  If necessary,
+	create the pipe and seed it with tokens.  Set the non-blocking bit
+	for the read fd.  Enable the signal handler for SIGCHLD even if we
+	have a non-hanging wait; it's needed to interrupt the select() in
+	job.c:start_waiting_job().
+
+	* make.h: Declare job_fds[].
+
+	* job.h (struct child): Add job_token field to store the token for
+	this job (if any).
+
+	* job.c (reap_children): When a child is fully reaped, release the
+	token back into the pipe.
+	(free_child): If the child to be freed still has a token, put it
+	back.
+	(new_job): Initialize the job_token member.
+	(start_waiting_job): For local jobs, if we're using the pipe, get
+	a token before we check the load, etc.  We do this by performing a
+	non-blocking read in a loop.  If the read fails, no token is
+	available.  Do a select on the fd to wait for a token.  We need to
+	re-enable the signal handler for SIGCHLD even if we have a
+	non-hanging waitpid() or wait3(), so that the signal will
+	interrupt the select() and we can wake up to reap children.
+	(child_handler): Re-enable the signal handler.  The count is still
+	kept although it's not needed or used unless you don't have
+	waitpid() or wait3().
+
+1999-04-10  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (main): Reset the considered bit on all the makefiles if
+	something failed to update; we need to examine them again if they
+	appear as normal targets in order to get the proper error message.
+
+1999-04-09  Paul D. Smith  <psmith@gnu.org>
+
+	Performance enhancement from Tim Magill <tim.magill@telops.gte.com>.
+
+	* remake.c (update_file): If you have large numbers of
+	dependencies and you run in parallel, make can spend considerable
+	time each pass through the graph looking at branches it has
+	already seen.  Since we only reap_children() when starting a pass,
+	not in the middle, if a branch has been seen already in that pass
+	nothing interesting can happen until the next pass.  So, we toggle
+	a bit saying whether we've seen this target in this pass or not.
+	(update_goal_chain): Initially set the global considered toggle to
+	1, since all targets initialize their boolean to 0.  At the end of
+	each pass, toggle the global considered variable.
+	* filedef.h (struct file): Per-file considered toggle bit.
+	* file.c: New global toggle variable considered.
+
+1999-04-05  Paul D. Smith  <psmith@gnu.org>
+
+	* arscan.c (ar_scan): Added support for ARFZMAG (compressed
+	archives?) for Digital UNIX C++.  Information provided by
+	Patrick	E. Krogel <pekrogel@mtu.edu>.
+	(ar_member_touch): Ditto.
+
+1999-04-03  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (f_mtime): If: a) we found a file and b) we didn't
+	create it and c) it's not marked as an implicit target and d) it
+	is marked as an intermediate target, then it was so marked due to
+	an .INTERMEDIATE special target, but it already existed in the
+	directory.  In this case, unset the intermediate flag so we won't
+	delete it when make is done.  It feels like it would be cleaner to
+	put this check in update_file_1() but I worry it'll get missed...
+
+1999-04-01  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (construct_command_argv_internal): Use bcopy() to copy
+	overlapping strings, rather than strcpy().  ISO C says the latter
+	is undefined.  Found this in a bug report from 1996!  Ouch!
+
+1999-03-31  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (readline): Ignore carriage returns at the end of the
+	line, to allow Windows-y CRLF line terminators.
+
+1999-03-30  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Don't put build.sh here, since build.sh.in doesn't
+	exist initially.  This cause autoreconf and automake to fail when
+	run on a clean CVS checkout.  Instead, we create build.sh in the
+	Makefile (see below).
+
+	* Makefile.am: Remove BUILT_SOURCES; this is no longer relevant.
+	Put those files directly into EXTRA_DIST so they're distributed.
+	Create a local build rule to create build.sh.
+	Create a local maintainer-clean rule to delete all the funky
+	maintainers files.
+
+	* maintMakefile: Makefile.in depends on README, since automake
+	fails if it doesn't exist.  Also don't remove glob/Makefile.in
+	here, as it causes problems.
+
+1999-03-26  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Substitute GLOBLIB if we need the link the
+	glob/libglob.a library.
+	* Makefile.am (make_LDADD): Use the subst variable GLOBLIB so we
+	don't link the local libglob.a at all if we don't need it.
+	* build.template: Don't compile glob/*.o unless we want globlib.
+	* maintMakefile (build.sh.in): Substitute the glob/*.o files
+	separately.
+
+1999-03-25  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo: Various typos and additions, pointed out by James
+	G. Sack <jsack@dornfeld.com>.
+
+1999-03-22  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo (Functions): Add a new section documenting the new
+	$(error ...) and $(warning ...) functions.  Also updated copyright
+	dates.
+	* NEWS: Updated for the new functions.
+	* function.c (func_error): Implement the new $(error ...) and
+	$(warning ...) functions.
+	(function_table): Insert new functions into the table.
+	(func_firstword): Don't call find_next_token() with argv[0]
+	itself, since that function modifies the pointer.
+	* function.c: Cleanups and slight changes to the new method of
+	calling functions.
+
+1999-03-20  Han-Wen Nienhuys  <hanwen@cs.uu.nl>
+
+	* function.c: Rewrite to use one C function per make function,
+	instead of a huge switch statement.  Also allows some cleanup of
+	multi-architecture issues, and a cleaner API which makes things
+	like func_apply() simple.
+
+	* function.c (func_apply): Initial implementation.  Expand either
+	a builtin function or a make variable in the context of some
+	arguments, provided as $1, $2, ... $N.
+
+1999-03-19  Eli Zaretskii  <eliz@is.elta.co.il>
+1999-03-19  Rob Tulloh  <rob_tulloh@dev.tivoli.com>
+
+	* job.c (construct_command_argv_internal): Don't treat _all_
+	backslashes as escapes, only those which really escape a special
+	character.  This allows most normal "\" directory separators to be
+	treated normally.
+
+1999-03-05  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Check for a system strdup().
+	* misc.c (xstrdup): Created.  Suggestion by Han-Wen Nienhuys
+	<hanwen@cs.uu.nl>.
+	* make.h: Prototype xstrdup().
+	* remake.c (library_search): Use it.
+	* main.c (main): Use it.
+	(find_and_set_default_shell): Use it.
+	* job.c (construct_command_argv_internal): Use it.
+	* dir.c (find_directory): Use it.
+
+	* Makefile.am, configure.in: Use AC_SUBST_FILE to insert the
+	maintMakefile instead of "include", to avoid automake 1.4
+	incompatibility.
+
+1999-03-04  Paul D. Smith  <psmith@gnu.org>
+
+	* amiga.c, amiga.h, ar.c, arscan.c, commands.c, commands.h,
+	* default.c, dep.h, dir.c, expand.c, file.c, filedef.h, function.c,
+	* implicit.c, job.c, job.h, main.c, make.h, misc.c, read.c, remake.c
+	* remote-cstms.c, remote-stub.c, rule.h, variable.c, variable.h,
+	* vpath.c, Makefile.ami, NMakefile.template, build.template,
+	* makefile.vms: Updated FSF address in the copyright notice.
+
+	* variable.c (try_variable_definition): If we see a conditional
+	variable and we decide to set it, re-type it as recursive so it
+	will be expanded properly later.
+
+1999-02-22  Paul D. Smith  <psmith@gnu.org>
+
+	* NEWS: Mention new .LIBPATTERNS feature.
+
+	* make.texinfo (Libraries/Search): Describe the use and
+	ramifications of the new .LIBPATTERNS variable.
+
+	* remake.c (library_search): Instead of searching only for the
+	hardcoded expansion "libX.a" for a library reference "-lX", we
+	obtain a list of patterns from the .LIBPATTERNS variable and
+	search those in order.
+
+	* default.c: Added a new default variable .LIBPATTERNS.  The
+	default for UNIX is "lib%.so lib%.a".  Amiga and DOS values are
+	also provided.
+
+	* read.c: Remove bogus HAVE_GLOB_H references; always include
+	vanilla glob.h.
+
+1999-02-21  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (expand_function): Set value to 0 to avoid freeing it.
+	* variable.c (pop_variable_scope): Free the value of the variable.
+	(try_variable_definition): For simple variables, use
+	allocated_variable_expand() to avoid stomping on the variable
+	buffer when we still need it for other things.
+
+	* arscan.c: Modified to support AIX 4.3 big archives.  The changes
+	are based on information provided by Phil Adams
+	<padams@austin.ibm.com>.
+
+1999-02-19  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Check to see if the GNU glob library is already
+	installed on the system.  If so, _don't_ add -I./glob to the
+	compile line.  Using the system glob code with the local headers
+	is very bad mojo!
+	Rewrite SCCS macros to use more autoconf facilities.
+
+	* Makefile.am: Move -Iglob out of INCLUDES; it'll get added to
+	CPPFLAGS by configure now.
+	Automake 1.4 introduced its own "include" feature which conflicts
+	with the maintMakefile stuff.  A hack that seems to work is add a
+	space before the include :-/.
+
+	* build.template: Move -Iglob out of the compile line; it'll get
+	added to CPPFLAGS by configure now.
+
+1999-02-16  Glenn D. Wolf  <Glenn_Wolf@email.sps.mot.com>
+
+	* arscan.c (ar_scan) [VMS]: Initialized VMS_member_date before
+	calling lbr$get_index since if the archive is empty,
+	VMS_get_member_info won't get called at all, and any leftover date
+	will be used.  This bug shows up if any member of any archive is
+	made, followed by a dependency check on a different, empty
+	archive.
+
+1998-12-13  Martin Zinser  <zinser@decus.decus.de>
+
+	* config.h-vms [VMS]: Set _POSIX_C_SOURCE.  Redefine the getopt
+	functions so we don't use the broken VMS versions.
+	* makefile.com [VMS]: Allow debugging.
+	* dir.c (dir_setup_glob) [VMS]: Don't extern stat() on VMS.
+
+1998-11-30  Paul D. Smith  <psmith@gnu.org>
+
+	* signame.c (init_sig): Check the sizes of signals being set up to
+	avoid array overwrites (if the system headers have problems).
+
+1998-11-17  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (record_files): Clean up some indentation.
+
+1998-11-08  Han-Wen Nienhuys  <hanwen@cs.uu.nl>
+
+	* rule.c (print_rule_data_base): Fix arguments to fatal() call.
+
+1998-10-13  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (start_job_command): If the command list resolves to no
+	chars at all (e.g.: "foo:;$(empty)") then command_ptr is NULL;
+	quit early.
+
+1998-10-12  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>
+
+	* rule.c (print_rule_data_base): Ignore num_pattern_rules if it is
+	zero.
+
+1998-10-09  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): Allow non-empty lines to expand to the
+	empty string after variable, etc., expansion, and be ignored.
+
+1998-09-21  Paul D. Smith  <psmith@gnu.org>
+
+	* job.c (construct_command_argv_internal): Only add COMMAND.COM
+	"@echo off" line for non-UNIXy shells.
+
+1998-09-09  Paul D. Smith  <psmith@gnu.org>
+
+	* w32/subproc/sub_proc.c: Add in missing HAVE_MKS_SHELL tests.
+
+1998-09-04  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): If we hit the "missing separator" error,
+	check for the common case of 8 spaces instead of a TAB and give an
+	extra comment to help people out.
+
+1998-08-29  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.in (AC_STRUCT_ST_MTIM_NSEC):
+	Renamed from AC_STRUCT_ST_MTIM.
+
+	* acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC):  Likewise.
+	Port to UnixWare 2.1.2 and pedantic Solaris 2.6.
+
+	* acconfig.h (ST_MTIM_NSEC):
+	Renamed from HAVE_ST_MTIM, with a new meaning.
+
+	* filedef.h (FILE_TIMESTAMP_FROM_S_AND_NS):
+	Use new ST_MTIM_NSEC macro.
+
+1998-08-26  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (check_dep): For any intermediate file, not just
+	secondary ones, try implicit and default rules if no explicit
+	rules are given.  I'm not sure why this was restricted to
+	secondary rules in the first place.
+
+1998-08-24  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo (Special Targets): Update documentation for
+	.INTERMEDIATE: if used with no dependencies, then it does nothing;
+	old docs said it marked all targets as intermediate, which it
+	didn't... and which would be silly :).
+
+	* implicit.c (pattern_search): If we find a dependency in our
+	internal tables, make sure it's not marked intermediate before
+	accepting it as a found_file[].
+
+1998-08-20  Paul D. Smith  <psmith@gnu.org>
+
+	* ar.c (ar_glob): Use existing alpha_compare() with qsort.
+	(ar_glob_alphacompare): Remove it.
+
+	Modify Paul Eggert's patch so we don't abandon older systems:
+
+	* configure.in: Warn the user if neither waitpid() nor wait3() is
+	available.
+
+	* job.c (WAIT_NOHANG): Don't syntax error on ancient hosts.
+	(child_handler, dead_children): Define these if WAIT_NOHANG is not
+	available.
+	(reap_children): Only track the dead_children count if no
+	WAIT_NOHANG.  Otherwise, it's a boolean.
+
+	* main.c (main): Add back signal handler if no WAIT_NOHANG is
+	available; only use default signal handler if it is.
+
+1998-08-20  Paul Eggert  <eggert@twinsun.com>
+
+	Install a more robust signal handling mechanism for systems which
+	support it.
+
+	* job.c (WAIT_NOHANG): Define to a syntax error if our host
+	is truly ancient; this should never happen.
+	(child_handler, dead_children): Remove.
+	(reap_children): Don't try to keep separate track of how many
+	dead children we have, as this is too bug-prone.
+	Just ask the OS instead.
+	(vmsHandleChildTerm): Fix typo in error message; don't mention
+	child_handler.
+
+	* main.c (main): Make sure we're not ignoring SIGCHLD/SIGCLD;
+	do this early, before we could possibly create a subprocess.
+	Just use the default behavior; don't have our own handler.
+
+1998-08-18  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* read.c (read_makefile) [__MSDOS__, WINDOWS32]: Add code to
+	recognize library archive members when dealing with drive spec
+	mess.  Discovery and initial fix by George Racz <gracz@mincom.com>.
+
+1998-08-18  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Check for stdlib.h explicitly (some hosts have it
+	but don't have STDC_HEADERS).
+	* make.h: Use HAVE_STDLIB_H.  Clean up some #defines.
+	* config.ami: Re-compute based on new config.h.in contents.
+	* config.h-vms: Ditto.
+	* config.h.W32: Ditto.
+	* configh.dos: Ditto.
+
+	* dir.c (find_directory) [WINDOWS32]: Windows stat() fails if
+	directory names end with `\' so strip it.
+
+1998-08-17  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo: Added copyright year to the printed copy.  Removed
+	the price from the manual.  Change the top-level reference to
+	running make to be "Invoking make" instead of "make Invocation",
+	to comply with GNU doc standards.
+
+	* make.h (__format__, __printf__): Added support for these in
+	__attribute__ macro.
+	(message, error, fatal): Use ... prototype form under __STDC__.
+	Add __format__ attributes for printf-style functions.
+
+	* configure.in (AC_FUNC_VPRINTF): Check for vprintf()/_doprnt().
+
+	* misc.c (message, error, fatal): Add preprocessor stuff to enable
+	creation of variable-argument functions with appropriate
+	prototypes, that works with ANSI, pre-ANSI, varargs.h, stdarg.h,
+	v*printf(), _doprnt(), or none of the above.  Culled from GNU
+	fileutils and slightly modified.
+	(makefile_error, makefile_error): Removed (merged into error() and
+	fatal(), respectively).
+	* amiga.c: Use them.
+	* ar.c: Use them.
+	* arscan.c: Use them.
+	* commands.c: Use them.
+	* expand.c: Use them.
+	* file.c: Use them.
+	* function.c: Use them.
+	* job.c: Use them.
+	* main.c: Use them.
+	* misc.c: Use them.
+	* read.c: Use them.
+	* remake.c: Use them.
+	* remote-cstms.c: Use them.
+	* rule.c: Use them.
+	* variable.c: Use them.
+
+	* make.h (struct floc): New structure to store file location
+	information.
+	* commands.h (struct commands): Use it.
+	* variable.c (try_variable_definition): Use it.
+	* commands.c: Use it.
+	* default.c: Use it.
+	* file.c: Use it.
+	* function.c: Use it.
+	* misc.c: Use it.
+	* read.c: Use it.
+	* rule.c: Use it.
+
+1998-08-16  Paul Eggert  <eggert@twinsun.com>
+
+	* filedef.h (FILE_TIMESTAMP_PRINT_LEN_BOUND): Add 10, for nanoseconds.
+
+1998-08-16  Paul Eggert  <eggert@twinsun.com>
+
+	* filedef.h (FLOOR_LOG2_SECONDS_PER_YEAR): New macro.
+	(FILE_TIMESTAMP_PRINT_LEN_BOUND): Tighten bound, and try to
+	make it easier to understand.
+
+1998-08-14  Paul D. Smith  <psmith@gnu.org>
+
+	* read.c (read_makefile): We've already unquoted any colon chars
+	by the time we're done reading the targets, so arrange for
+	parse_file_seq() on the target list to not do so again.
+
+1998-08-05  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Added glob/configure.in data.  We'll have the glob
+	code include the regular make config.h, rather than creating its
+	own.
+
+	* getloadavg.c (main): Change return type to int.
+
+1998-08-01  Paul Eggert  <eggert@twinsun.com>
+
+	* job.c (reap_children): Ignore unknown children.
+
+1998-07-31  Paul D. Smith  <psmith@gnu.org>
+
+	* make.h, filedef.h, dep.h, rule.h, commands.h, remake.c:
+	Add prototypes for functions.  Some prototypes needed to be moved
+	in order to get #include order reasonable.
+
+1998-07-30  Paul D. Smith  <psmith@gnu.org>
+
+	* make.h: Added MIN/MAX.
+	* filedef.h: Use them; remove FILE_TIMESTAMP_MIN.
+
+1998-07-30  Paul Eggert  <eggert@twinsun.com>
+
+        Add support for sub-second timestamp resolution on hosts that
+        support it (just Solaris 2.6, so far).
+
+	* acconfig.h (HAVE_ST_MTIM, uintmax_t): New undefs.
+	* acinclude.m4 (jm_AC_HEADER_INTTYPES_H, AC_STRUCT_ST_MTIM,
+        jm_AC_TYPE_UINTMAX_T): New defuns.
+	* commands.c (delete_target): Convert file timestamp to
+        seconds before comparing to archive timestamp.  Extract mod
+        time from struct stat using FILE_TIMESTAMP_STAT_MODTIME.
+	* configure.in (C_STRUCT_ST_MTIM, jm_AC_TYPE_UINTMAX_T): Add.
+        (AC_CHECK_LIB, AC_CHECK_FUNCS): Add clock_gettime.
+	* file.c (snap_deps): Use FILE_TIMESTAMP, not time_t.
+        (file_timestamp_now, file_timestamp_sprintf): New functions.
+        (print_file): Print file timestamps as FILE_TIMESTAMP, not
+        time_t.
+	* filedef.h: Include <inttypes.h> if available and if HAVE_ST_MTIM.
+        (FILE_TIMESTAMP, FILE_TIMESTAMP_STAT_MODTIME, FILE_TIMESTAMP_MIN,
+        FILE_TIMESTAMPS_PER_S, FILE_TIMESTAMP_FROM_S_AND_NS,
+        FILE_TIMESTAMP_DIV, FILE_TIMESTAMP_MOD, FILE_TIMESTAMP_S,
+        FILE_TIMESTAMP_NS, FILE_TIMESTAMP_PRINT_LEN_BOUND): New macros.
+        (file_timestamp_now, file_timestamp_sprintf): New decls.
+        (struct file.last_mtime, f_mtime, file_mtime_1, NEW_MTIME):
+        time_t -> FILE_TIMESTAMP.
+	* implicit.c (pattern_search): Likewise.
+	* vpath.c (vpath_search, selective_vpath_search): Likewise.
+	* main.c (main): Likewise.
+	* remake.c (check_dep, name_mtime, library_search, f_mtime): Likewise.
+        (f_mtime): Use file_timestamp_now instead of `time'.
+        Print file timestamp with file_timestamp_sprintf.
+	* vpath.c (selective_vpath_search): Extract file time stamp from
+        struct stat with FILE_TIMESTAMP_STAT_MODTIME.
+
+1998-07-28  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.77 released.
+
+	* dosbuild.bat: Change to DOS CRLF line terminators.
+
+	* make-stds.texi: Update from latest version.
+
+	* make.texinfo (Options Summary): Clarify that the -r option
+	affects only rules, not builtin variables.
+
+1998-07-27  Paul D. Smith  <psmith@gnu.org>
+
+	* make.h: Make __attribute__ resolve to empty for non-GCC _and_
+	for GCC pre-2.5.x.
+
+	* misc.c (log_access): Print UID/GID's as unsigned long int for
+	maximum portability.
+
+	* job.c (reap_children): Print PIDs as long int for maximum
+	portability.
+
+1998-07-24  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* Makefile.DOS (*_INSTALL, *_UNINSTALL): Replace `true' with `:'.
+
+1998-07-25  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.76.94 released.
+
+1998-07-23  Paul D. Smith  <psmith@gnu.org>
+
+	* config.h.W32.template: Make sure all the #defines of macros here
+	have a value (e.g., use ``#define HAVE_STRING_H 1'' instead of
+	just ``#define HAVE_STRING_H''.  Keeps the preprocessor happy in
+	some contexts.
+
+	* make.h: Remove __attribute__((format...)) stuff; using it with
+	un-prototyped functions causes older GCC's to fail.
+
+	* Version 3.76.93 released.
+
+1998-07-22  Paul D. Smith  <psmith@gnu.org>
+
+	* file.c (print_file_data_base): Fix average calculation.
+
+1998-07-20  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (die): Postpone the chdir() until after
+	remove_intermediates() so that intermediate targets with relative
+	pathnames are removed properly.
+
+1998-07-17  Paul D. Smith  <psmith@gnu.org>
+
+	* filedef.h (struct file): New flag: did we print an error or not?
+
+	* remake.c (no_rule_error): New function to print error messages,
+	extraced from remake_file().
+
+	* remake.c (remake_file): Invoke the new error print function.
+	(update_file_1): Invoke the error print function if we see that we
+	already tried this target and it failed, but that an error wasn't
+	printed for it.  This can happen if a file is included with
+	-include or sinclude and couldn't be built, then later is also
+	the dependency of another target.  Without this change, make just
+	silently stops :-/.
+
+1998-07-16  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo: Removed "beta" version designator.
+	Updated ISBN for the next printing.
+
+1998-07-13  Paul Eggert  <eggert@twinsun.com>
+
+	* acinclude.m4: New AC_LFS macro to determine if special compiler
+	flags are needed to allow access to large files (e.g., Solaris 2.6).
+	* configure.in: Invoke it.
+
+1998-07-08  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* Makefile.DOS: track changes in Makefile.in.
+
+1998-07-07  Paul D. Smith  <psmith@gnu.org>
+
+	* remote-cstms.c (start_remote_job): Move gethostbyaddr() to the
+	top so host is initialized early enough.
+
+	* acinclude.m4: New file.  Need some special autoconf macros to
+	check for network libraries (-lsocket, -lnsl, etc.) when
+	configuring Customs.
+
+	* configure.in (make_try_customs): Invoke new network libs macro.
+
+1998-07-06  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.76.92 released.
+
+	* README.customs: Added to the distribution.
+
+	* configure.in (make_try_customs): Rewrite to require an installed
+	Customs library, rather than looking at the build directory.
+
+	* Makefile.am (man_MANS): Install make.1.
+	* make.1: Renamed from make.man.
+
+	* make.texinfo (Bugs): New mailing list address for GNU make bug
+	reports.
+
+1998-07-02  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.76.91 released.
+
+	* default.c: Added default rule for new-style RCS master file
+	storage; ``% :: RCS/%''.
+	Added default rules for DOS-style C++ files with suffix ".cpp".
+	They use the new LINK.cpp and COMPILE.cpp macros, which are set by
+	default to be equal to LINK.cc and COMPILE.cc.
+
+1998-06-19  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* job.c (start_job_command): Reset execute_by_shell after an empty
+        command was skipped.
+
+1998-06-09  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (main): Keep track of the temporary filename created when
+	reading a makefile from stdin (-f-) and attempt to remove it
+	as soon as we know we're not going to re-exec.  If we are, add it
+	to the exec'd make's cmd line with "-o" so the exec'd make doesn't
+	try to rebuild it.  We still have a hole: if make re-execs then
+	the temporary file will never be removed.  To fix this we'd need
+	a brand new option that meant "really delete this".
+	* AUTHORS, getopt.c, getopt1.c, getopt.h, main.c (print_version):
+	Updated mailing addresses.
+
+1998-06-08  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (main): Andreas Luik <luik@isa.de> points out that the
+	check for makefile :: rules with commands but no dependencies
+	causing a loop terminates incorrectly.
+
+	* maintMakefile: Make a template for README.DOS to update version
+	numbers.
+
+1998-05-30  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
+
+	* remake.c (update_file_1): Don't free the memory for the
+	dependency structure when dropping a circular dependency.
+
+1998-05-30  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* dir.c (file_exists_p, file_impossible_p, file_impossible)
+	[__MSDOS__, WINDOWS32]: Retain trailing slash in "d:/", and make
+	dirname of "d:foo" be "d:".
+
+1998-05-26  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
+
+	* read.c (read_makefile): Avoid running past EOS when scanning
+	file name after `include'.
+
+1998-05-26  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
+
+	* make.texinfo (Flavors): Correct description of conditional
+	assignment, which is not equivalent to ifndef.
+	(Setting): Likewise.
+
+1998-05-24  Paul D. Smith  <psmith@gnu.org>
+
+	* arscan.c (ar_name_equal): strncmp() might be implemented as a
+	macro, so don't put preprocessor conditions inside the arguments
+	list.
+
+1998-05-23  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* read.c (read_makefile) [__MSDOS__, WINDOWS32]: Skip colons in
+	drive specs when parsing targets, target-specific variables and
+	static pattern rules.  A colon can only be part of drive spec if
+	it is after the first letter in a token.
+
+1998-05-22  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* remake.c (f_mtime) [__MSDOS__]: Allow up to 3 sec of skew before
+	yelling bloody murder.
+
+	* dosbuild.bat: Use -DINCLUDEDIR= and -DLIBDIR= where appropriate.
+
+	* read.c (parse_file_seq): Combine the special file-handling code
+	for WINDOWS32 and __MSDOS__ into a single snippet.
+	(get_next_mword) [__MSDOS__, WINDOWS32]: Allow a word to include a
+	colon as part of a drive spec.
+
+	* job.c (batch_mode_shell) [__MSDOS__]: Declare.
+
+1998-05-20  Paul D. Smith  <psmith@gnu.org>
+
+	* Version 3.76.90 released.
+
+1998-05-19  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo (Make Errors): Added a new appendix describing
+	common errors make might generate and how to resolve them (or at
+	least more information on what they mean).
+
+	* maintMakefile (NMAKEFILES): Use the new automake 1.3 feature
+	to create a dependency file to construct Makefile.DOS, SMakefile,
+	and NMakefile.
+	(.dep_segment): Generate the dependency fragment file.
+
+1998-05-14  Paul D. Smith  <psmith@gnu.org>
+
+	* make.man: Minor changes.
+
+1998-05-13  Paul D. Smith  <psmith@gnu.org>
+
+	* function.c (pattern_matches,expand_function): Change variables
+	and types named "word" to something else, to avoid compilation
+	problems on Cray C90 Unicos.
+	* variable.h: Modify the function prototype.
+
+1998-05-11  Rob Tulloh  <rob_tulloh@tivoli.com>
+
+	* job.c (construct_command_argv_internal) [WINDOWS32]: Turn off
+	echo when using a batch file, and make sure the command ends in a
+	newline.
+
+1998-05-03  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in (make_try_customs): Add some customs flags if the
+	user configures custom support.
+
+	* job.c, remote-cstms.c: Merge in changes for custom library.
+
+	* remote-stub.c: Add option to stub start_remote_job_p().
+
+1998-05-01  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (f_mtime): Install VPATH+ handling for archives; use
+	the hname field instead of the name field, and rehash when
+	appropriate.
+
+1998-04-30  Paul D. Smith  <psmith@gnu.org>
+
+	* rule.c (print_rule_data_base): Print out any pattern-specific
+	variable values into the rules database.
+
+	* variable.c (print_variable_set): Make this variable extern, to
+	be called by print_rule_data_base() for pattern-specific variables.
+
+	* make.texinfo (Pattern-specific): Document pattern-specific
+	variables.
+
+1998-04-29  Paul D. Smith  <psmith@gnu.org>
+
+	* expand.c (variable_expand_for_file): Make static; its only
+	called internally.  Look up this target in the list of
+	pattern-specific variables and insert the variable set into the
+	queue to be searched.
+
+	* filedef.h (struct file): Add a new field to hold the
+	previously-found pattern-specific variable reference.  Add a new
+	flag to remember whether we already searched for this file.
+
+	* rule.h (struct pattern_var): New structure for storing
+	pattern-specific variable values.  Define new function prototypes.
+
+	* rule.c: New variables pattern_vars and last_pattern_var for
+	storage and handling of pattern-specific variable values.
+	(create_pattern_var): Create a new pattern-specific variable value
+	structure.
+	(lookup_pattern_var): Try to match a target to one of the
+	pattern-specific variable values.
+
+1998-04-22  Paul D. Smith  <psmith@gnu.org>
+
+	* make.texinfo (Target-specific): Document target-specific
+	variables.
+
+1998-04-21  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (define_variable_in_set): Made globally visible.
+	(lookup_variable_in_set): New function: like lookup_variable but
+	look only in a specific variable set.
+	(target_environment): Use lookup_variable_in_set() to get the
+	correct export rules for a target-specific variable.
+	(create_new_variable_set): Create a new variable set, and just
+	return it without installing it anywhere.
+	(push_new_variable_scope): Reimplement in terms of
+	create_new_variable_set.
+
+	* read.c (record_target_var): Like record_files, but instead of
+	files create a target-specific variable value for each of the
+	listed targets.  Invoked from read_makefile() when the target line
+	turns out to be a target-specific variable assignment.
+
+1998-04-19  Paul D. Smith <psmith@gnu.org>
+
+	* read.c (read_makefile): Rewrite the entire target parsing
+	section to implement target-specific variables.  In particular, we
+	cannot expand the entire line as soon as it's read in, since we
+	may want to evaluate parts of it with different variable contexts
+	active.  Instead, start expanding from the beginning until we find
+	the `:' (or `::'), then determine what kind of line this is and
+	continue appropriately.
+
+	* read.c (get_next_mword): New function to parse a makefile line
+	by "words", considering an entire variable or function as one
+	word.  Return the type read in, along with its starting position
+	and length.
+	(enum make_word_type): The types of words that are recognized by
+	get_next_mword().
+
+	* variable.h (struct variable): Add a flag to specify a per-target
+	variable.
+
+	* expand.c: Make variable_buffer global.  We need this during the
+	new parsing of the makefile.
+	(variable_expand_string): New function.  Like variable_expand(),
+	but start at a specific point in the buffer, not the beginning.
+	(variable_expand): Rewrite to simply call variable_expand_string().
+
+1998-04-13  Paul D. Smith  <psmith@gnu.org>
+
+	* remake.c (update_goal_chain): Allow the rebuilding makefiles
+	step to use parallel jobs.  Not sure why this was disabled:
+	hopefully we won't find out :-/.
+
+1998-04-11  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (main): Set the CURDIR makefile variable.
+	* make.texinfo (Recursion): Document it.
+
+1998-03-17  Paul D. Smith  <psmith@gnu.org>
+
+	* misc.c (makefile_fatal): If FILE is nil, invoke plain fatal().
+	* variable.c (try_variable_definition): Use new feature.
+
+1998-03-10  Paul D. Smith  <psmith@gnu.org>
+
+	* main.c (main): Don't pass included, rebuilt makefiles to
+	re-exec'd makes with -o.  Reopens a possible loop, but it caused
+	too many problems.
+
+1998-03-02  Paul D. Smith  <psmith@gnu.org>
+
+	* variable.c (try_variable_definition): Implement ?=.
+	* make.texinfo (Setting): Document it.
+
+1998-02-28  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* job.c (start_job_command): Reset execute_by_shell after an empty
+        command, like ":", has been seen.
+
+Tue Oct 07 15:00:00 1997  Phil Brooks <phillip_brooks@hp.com>
+
+	* make.h [WINDOWS32]: make case sensitivity configurable
+	* dir.c [WINDOWS32]: make case sensitivity configurable
+	* README.W32: Document case sensitivity
+	* config.ami: Share case warping code with Windows
+
+Mon Oct  6 18:48:45 CDT 1997 Rob Tulloh <rob_tulloh@dev.tivoli.com>
+
+	* w32/subproc/sub_proc.c: Added support for MKS toolkit shell
+	(turn on HAVE_MKS_SHELL).
+	* read.c [WINDOWS32]: Fixed a problem with multiple target rules
+ 	reported by Gilbert Catipon (gcatipon@tibco.com).  If multiple
+ 	path tokens in a rule did not have drive letters, make would
+ 	incorrectly concatenate the 2 tokens together.
+	* main.c/variable.c [WINDOWS32]: changed SHELL detection code to
+ 	follow what MSDOS did. In addition to watching for SHELL variable
+ 	updates, make's main will attempt to default the value of SHELL
+ 	before and after makefiles are parsed.
+	* job.c/job.h [WINDOWS32]: The latest changes made to enable use
+ 	of the GNUWIN32 shell from make could cause make to fail due to a
+ 	concurrency condition between parent and child processes.  Make
+ 	now creates a batch file per job instead of trying to reuse the
+ 	same singleton batch file.
+	* job.c/job.h/function.c/config.h.W32 [WINDOWS32]: Renamed macro
+ 	from HAVE_CYGNUS_GNUWIN32_TOOLS to BATCH_MODE_ONLY_SHELL. Reworked
+ 	logic to reduce complexity. WINDOWS32 now uses the unixy_shell
+ 	variable to detect Bourne-shell compatible environments. There is
+ 	also a batch_mode_shell variable that determines whether not
+ 	command lines should be executed via script files. A WINDOWS32
+ 	system with no sh.exe installed would have unixy_shell set to
+ 	FALSE and batch_mode_shell set to TRUE. If you have a unixy shell
+ 	that does not behave well when invoking things via 'sh -c xxx',
+ 	you may want to turn on BATCH_MODE_ONLY_SHELL and see if things
+ 	improve.
+	* NMakefile: Added /D DEBUG to debug build flags so that unhandled
+ 	exceptions could be debugged.
+
+Mon Oct  6 00:04:25 1997  Rob Tulloh <rob_tulloh@dev.tivoli.com>
+
+	* main.c [WINDOWS32]: The function define_variable() does not
+ 	handle NULL. Test before calling it to set Path.
+	* main.c [WINDOWS32]: Search Path again after makefiles have been
+	parsed to detect sh.exe.
+	* job.c [WINDOWS32]: Added support for Cygnus GNU WIN32 tools.
+	To use, turn on HAVE_CYGNUS_GNUWIN32_TOOLS in config.h.W32.
+	* config.h.W32: Added HAVE_CYGNUS_GNUWIN32_TOOLS macro.
+
+Sun Oct  5 22:43:59 1997  John W. Eaton <jwe@bevo.che.wisc.edu>
+
+	* glob/glob.c (glob_in_dir) [VMS]: Globbing shouldn't be
+	case-sensitive.
+	* job.c (child_execute_job) [VMS]: Use a VMS .com file if the
+	command contains a newline (e.g. from a define/enddef block).
+	* vmsify.c (vmsify): Return relative pathnames wherever possible.
+	* vmsify.c (vmsify): An input string like "../.." returns "[--]".
+
+Wed Oct  1 15:45:09 1997  Rob Tulloh <rob_tulloh@tivoli.com>
+
+	* NMakefile: Changed nmake to $(MAKE).
+	* subproc.bat: Take the make command name from the command
+	line. If no command name was given, default to nmake.
+	* job.c [MSDOS, WINDOWS32]: Fix memory stomp: temporary file names
+	are now always created in heap memory.
+	* w32/subproc/sub_proc.c: New implementation of make_command_line()
+	which is more compatible with different Bourne shell implementations.
+	Deleted the now obsolete fix_command_line() function.
+	* main.c [WINDOWS32]: Any arbitrary spelling of Path can be
+	detected. Make will ensure that the special spelling `Path' is
+	inserted into the environment when the path variable is propagated
+	within itself and to make's children.
+	* main.c [WINDOWS32]: Detection of sh.exe was occurring too
+	soon. The 2nd check for the existence of sh.exe must come after
+	the call to read_all_makefiles().
+
+Fri Sep 26 01:14:18 1997  <zinser@axp602.gsi.de>
+
+	* makefile.com [VMS]: Fixed definition of sys.
+	* readme.vms: Comments on what's changed lately.
+
+Fri Sep 26 01:14:18 1997  John W. Eaton <jwe@bevo.che.wisc.edu>
+
+	* read.c (read_all_makefiles): Allow make to find files named
+	"MAKEFILE" with no extension on VMS.
+	* file.c (lookup_file): Lowercase filenames on VMS.
+
+1997-09-29  Paul D. Smith  <psmith@baynetworks.com>
+
+	* read.c (read_makefile): Reworked target detection again; the old
+	version had an obscure quirk.
+
+Fri Sep 19 09:20:49 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* Version 3.76.1 released.
+
+	* Makefile.am: Add loadavg files to clean rules.
+
+	* configure.in (AC_OUTPUT): Remove stamp-config; no longer needed.
+	* Makefile.ami (distclean): Ditto.
+	* SMakefile (distclean): Ditto.
+
+	* main.c (main): Arg count should be int, not char!  Major braino.
+
+Tue Sep 16 10:18:22 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* Version 3.76 released.
+
+Tue Sep  2 10:07:39 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* function.c (expand_function): When processing $(shell...)
+  	translate a CRLF (\r\n) sequence as well as a newline (\n) to a
+ 	space.  Also remove an ending \r\n sequence.
+	* make.texinfo (Shell Function): Document it.
+
+Fri Aug 29 12:59:06 1997  Rob Tulloh  <rob_tulloh@tivoli.com>
+
+	* w32/pathstuff.c (convert_Path_to_windows32): Fix problem where
+ 	paths which contain single character entries like `.' are not
+ 	handled correctly.
+
+	* README.W32: Document path handling issues on Windows systems.
+
+Fri Aug 29 02:01:27 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* Version 3.75.93.
+
+Thu Aug 28 19:39:06 1997  Rob Tulloh  <rob_tulloh@tivoli.com>
+
+	* job.c (exec_command) [WINDOWS32]: If exec_command() is invoked
+ 	from main() to re-exec make, the call to execvp() would
+ 	incorrectly return control to parent shell before the exec'ed
+ 	command could run to completion. I believe this is a feature of
+ 	the way that execvp() is implemented on top of WINDOWS32 APIs. To
+ 	alleviate the problem, use the supplied process launch function in
+ 	the sub_proc library and suspend the parent process until the
+ 	child process has run.  When the child exits, exit the parent make
+ 	with the exit code of the child make.

+
+	* configure.in: Require autoconf 2.12

+	* remake.c (f_mtime): Test and set it.
+
+	* job.c (start_job_command): Add special optimizations for
+ 	"do-nothing" rules, containing just the shell no-op ":".  This is
+ 	useful for timestamp files and can make a real difference if you
+ 	have a lot of them (requested by Fergus Henderson <fjh@cs.mu.oz.au>).
+
+	* configure.in,Makefile.in: Rewrote to use the new autoconf
+	program_transform_name macro.

+
+Fri Jun  6 23:41:04 1997  Rob Tulloh <rob_tulloh@tivoli.com>
+
+	* remake.c (f_mtime): Datestamps on FAT-based files are rounded to
+	even seconds when stored, so if the date check fails on WINDOWS32
+	 systems, see if this "off-by-one" error is the problem.
+
+	* General: If your TZ environment variable is not set correctly
+	then all your timestamps will be off by hours.  So, set it!

+
+	* Version 3.75.1
+
+	* compatMakefile (objs): Define & use the $(GLOB) variable so
+	that it's removed correctly from build.sh.in when it's built.

+	error, rather than failing.
+
+	* main.c (main): If we rebuild any makefiles and need to re-exec,

+	* dir.c (find_directory): W32: Find the filesystem type.
+	(dir_contents_file_exists_p): W32: for FAT filesystems, always
+	rehash since FAT doesn't change directory mtime on change.
+
+	* main.c (handle_runtime_exceptions): W32: Add an
+ 	UnhandledExceptionFilter so that when make bombs due to ^C or a

+Mon Mar 24 00:57:34 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* configure.in, config.h.in, config.ami, config.h-vms, config.h.w32:
+ 	Check for memmove() function.
+
+	* make.h (bcopy): If memmove() available, define bcopy() to use it.
+	Otherwise just use bcopy().  Don't use memcpy(); it's not guaranteed
+	to handle overlapping moves.
+
+	* read.c (read_makefile): Fix some uninitialized memory reads
+	(reported by Purify).
+
+	* job.c (construct_command_argv_internal): Use bcopy() not
+	strcpy(); strcpy() isn't guaranteed to handle overlapping moves.
+
+	* Makefile.in: Change install-info option ``--infodir'' to
+	``--info-dir'' for use with new texinfo.
+
+	* function.c (expand_function): $(basename) and $(suffix) should
+	only search for suffixes as far back as the last directory (e.g.,
+	only the final filename in the path).
+
+Sun Mar 23 00:13:05 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* make.texinfo: Add @dircategory/@direntry information.
+	(Top): Remove previous reference to (dir) (from RMS).
+	(Static Usage): Add "all:" rule to example.
+	(Automatic Dependencies): fix .d file creation example.
+
+	* Install VPATH+ patch:
+
+	* filedef.h (struct file): Add in hname field to store the hashed
+        filename, and a flag to remember if we're using the vpath filename
+	or not.  Renamed a few functions for more clarity.
+
+	* file.c (lookup_file,enter_file,file_hash_enter): Store filenames
+	in the hash table based on their "hash name".  We can change this
+	while keeping the original target in "name".
+	(rehash_file): Renamed from "rename_file" to be more accurate.
+	Changes the hash name, but not the target name.
+
+	* remake.c (update_file_1): Modify -d output for more detailed
+ 	VPATH info.  If we don't need to rebuild, use the VPATH name.
+	(f_mtime): Don't search for vpath if we're ignoring it.  Call
+ 	renamed function rehash_file.  Call name_mtime instead of
+ 	file_mtime, to avoid infinite recursion since the file wasn't
+ 	actually renamed.
+
+	* implicit.c (pattern_search): if we find an implicit file in
+	VPATH, save the original name not the VPATH name.
+
+	* make.texinfo (Directory Search): Add a section on the new VPATH
+	functionality.
+
+Sun Dec  1 18:36:04 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>
+
+	* dir.c (file_exists_p, file_impossible, file_impossible_p): If
+	dirname is empty replace it by the name of the root directory.

+ 	already.
+
+Sun Jul 28 15:37:09 1996  Rob Tulloh (tulloh@tivoli.com)
+
+	* w32/pathstuff.c: Turned convert_vpath_to_w32() into a
+	real function. This was done so that VPATH could contain
+	white space separated pathnames. Please note that directory
+	paths (in VPATH/vpath context) containing white space are not
+	supported (just as they are not under Unix). See README.W32
+	for suggestions.
+
+	* w32/include/pathstuff.h: Added prototype for the new
+	function convert_vpath_to_w32. Deleted macro for same.
+
+	* README.W32: Added some notes about why I chose not to try
+	and support pathnames which contain white space and some
+	workaround suggestions.
+
+Thu Jul 25 19:53:31 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

+
+	* read.c (find_char_unquote): Avoid calling strlen on every call

+
+Wed May 15 17:37:26 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	* dir.c (print_dir_data_base): Use %ld dev and ino and cast them to
+	long.
+
+Wed May 15 10:14:14 CDT 1996  Rob Tulloh  <tulloh@tivoli.com>
+
+	* dir.c: W32 does not support inode. For now, fully qualified
+	pathname along with st_mtime will be keys for files.
+	Fixed problem where vpath can be confused when files
+	are added to a directory after the directory has already been
+	read in. The code now attempts to reread the directory if it
+	discovers that the datestamp on the directory has changed since
+	it was cached by make. This problem only seems to occur on W32
+	right now so it is lumped under port #ifdef WINDOWS32.
+
+	* function.c: W32: call subproc library (CreateProcess()) instead of
+	fork/exec.
+
+	* job.c: W32: Added the code to do fork/exec/waitpid style processing
+	on W32 systems via calls to subproc library.
+
+	* main.c: W32: Several things added here. First, there is code
+	for dealing with PATH and SHELL defaults. Make tries to figure
+	out if the user has %PATH% set in the environment and sets it to
+	%Path% if it is not set already. Make also looks to see if sh.exe
+	is anywhere to be found. Code path through job.c will change
+	based on existence of a working Bourne shell. The checking for
+	default shell is done twice: once before makefiles are read in
+	and again after. Fall back to MSDOS style execution mode if no sh.exe
+	is found. Also added some debug support that allows user to pause make
+	with -D switch and attach a debugger. This is especially useful for
+	debugging recursive calls to make where problems appear only in the
+	sub-make.
+
+	* make.h: W32: A few macros and header files for W32 support.
+
+	* misc.c: W32: Added a function end_of_token_w32() to assist
+	in parsing code in read.c.
+
+	* read.c: W32: Fixes similar to MSDOS which allow colon to
+	appear in filenames. Use of colon in filenames would otherwise
+	confuse make.
+
+	* remake.c: W32: Added include of io.h to eliminate compiler
+	warnings. Added some code to default LIBDIR if it is not set
+	on W32.
+
+	* variable.c: W32: Added support for detecting Path/PATH
+	and converting them to semicolon separated lists for make's
+	internal use. New function sync_Path_environment()
+	which is called in job.c and function.c before creating a new
+	process. Caller must set Path in environment since we don't
+	have fork() to do this for us.
+
+	* vpath.c: W32: Added detection for filenames containing
+	forward or backward slashes.
+
+	* NMakefile: W32: Visual C compatible makefile for use with nmake.
+	Use this to build GNU make the first time on Windows NT or Windows 95.
+
+	* README.W32: W32: Contains some helpful notes.
+
+	* build_w32.bat: W32: If you don't like nmake, use this the first
+	time you build GNU make on Windows NT or Windows 95.
+
+	* config.h.W32: W32 version of config.h
+
+	* subproc.bat: W32: A bat file used to build the
+	subproc library from the top-level NMakefile. Needed because
+	WIndows 95 (nmake) doesn't allow you to cd in a make rule.
+
+	* w32/include/dirent.h
+	* w32/compat/dirent.c: W32: opendir, readdir, closedir, etc.
+
+	* w32/include/pathstuff.h: W32: used by files needed functions
+	defined in pathstuff.c (prototypes).
+

+Mon May 13 14:37:42 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	* Version 3.74.4.
+
+	* GNUmakefile (vmsfiles): Fix typo.
+
+	* GNUmakefile (amigafiles): Add amiga.h.
+
+Sun May 12 19:19:43 1996  Aaron Digulla   <digulla@fh-konstanz.de>
+
+	* dir.c: New function: amigafy() to fold filenames
+	Changes HASH() to HASHI() to fold filenames on Amiga.
+	Stringcompares use strieq() instead of streq()
+	The current directory on Amiga is "" instead of "."
+	* file.c: Likewise.
+
+	* amiga.c: New function wildcard_expansion(). Allows to use
+	Amiga wildcards with $(wildcard )
+
+	* amiga.h: New file. Prototypes for amiga.c
+
+	* function.c: Use special function wildcard_expansion() for
+	$(wildcard ) to allow Amiga wildcards
+	The current directory on Amiga is "" instead of "."
+
+	* job.c: No Pipes on Amiga, too
+	(load_too_high) Neither on Amiga
+	ENV variable on Amiga are in a special directory and are not
+	passed as third argument to main().
+
+	* job.h: No envp on Amiga
+
+	* make.h: Added HASHI(). This is the same as HASH() but converts
+	it's second parameter to lowercase on Amiga to fold filenames.
+
+	* main.c: (main), variable.c Changed handling of ENV-vars. Make
+	stores now the names of the variables only and reads their contents
+	when they are accessed to reflect that these variables are really
+	global (ie. they CAN change WHILE make runs !) This handling is
+	made in lookup_variable()
+
+	* Makefile.ami: renamed file.h to filedep.h
+	Updated dependencies
+
+	* read.c: "find_semicolon" is declared as static but never defined.
+	No difference between Makefile and makefile on Amiga; added
+	SMakefile to *default_makefiles[].
+	(read_makefile) SAS/C want's two_colon and pattern_percent be set
+	before use.
+	The current directory on Amiga is "" instead of "."
+	Strange #endif moved.
+
+	* README.Amiga: updated feature list
+
+	* SMakefile: Updated dependencies
+
+	* variable.c: Handling of ENV variable happens inside lookup_variable()
+
+Sat May 11 17:58:32 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	* variable.c (try_variable_definition): Count parens in lhs variable
+	refs to avoid seeing =/:=/+= inside a ref.
+
+Thu May  9 13:54:49 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	* commands.c (fatal_error_signal) [SIGQUIT]: Make SIGQUIT check
+	conditional.
+
+	* main.c (main): Use unsigned for fread return.
+
+	* read.c (parse_file_seq): Use `int' for char arg to avoid widening
+	conflict issues.
+	* dep.h: Fix prototype.
+
+	* function.c (expand_function) [_AMIGA]: Fix some typos.
+	(patsubst_expand): Make len vars unsigned.

+	(amigafiles): New variable.
+
+Thu Nov  7 10:18:16 1995  Aaron Digulla   <digulla@fh-konstanz.de>
+
+	* Added Amiga support in commands.c, dir.c, function.c,
+	job.c, main.c, make.h, read.c, remake.c
+	* commands.c: Amiga has neither SIGHUP nor SIGQUIT
+	* dir.c: Amiga has filenames with Upper- and Lowercase,
+	but "FileName" is the same as "filename". Added strieq()
+	which is use to compare filenames. This is like streq()
+	on all other systems. Also there is no such thing as
+	"." under AmigaDOS.
+	* function.c: On Amiga, the environment is not passed as envp,
+	there are no pipes and Amiga can't fork. Use my own function
+	to create a new child.
+	* job.c: default_shell is "" (The system automatically chooses
+	a shell for me). Have to use the same workaround as MSDOS for
+	running batch commands. Added HAVE_SYS_PARAM_H. NOFILE isn't
+	known on Amiga. Cloned code to run children from MSDOS. Own
+	version of sh_chars[] and sh_cmds[]. No dup2() or dup() on Amiga.
+	* main.c: Force stack to 20000 bytes. Read environment from ENV:
+	device. On Amiga, exec_command() does return, so I exit()
+	afterwards.
+	* make.h: Added strieq() to compare filenames.
+	* read.c: Amiga needs special extension to have passwd. Only
+	one include-dir. "Makefile" and "makefile" are the same.
+	Added "SMakefile".  Added special code to handle device names (xxx:)
+	and "./" in rules.
+	* remake.c: Only one lib-dir. Amiga link-libs are named "%s.lib"
+	instead of "lib%s.a".
+	* main.c, rule.c, variable.c: Avoid floats at all costs.
+	* vpath.c: Get rid of as many alloca()s as possible.
+
+Thu May  9 13:20:43 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

+	no single-letter version is no longer indicated by a value of -1;
+	instead a value that is !isalnum.
+	(init_switches): Don't put such switches into the string, only
+	into the long_option table.
+
+	* make.h [!NSIG] [!_NSIG]: #define NSIG 32.
+
+	* job.c [HAVE_WAITPID]: Remove #undef HAVE_UNION_WAIT.  AIX's

+	[__GNU_LIBRARY__ || POSIX]: Don't #include <unistd.h> again.
+	* main.c (main): Handle SIGCHLD if defined, and SIGCLD if defined.
+	It doesn't hurt to do both if they are both defined, and testing
+	USG is useless.
+	* dir.c: Rationalize directory header conditionals.
+	* arscan.c [HAVE_FCNTL_H]: Test this rather than USG || POSIX.
+
+	* default.c (default_suffixes): Add `.txinfo'.

+	on FLAVOR.  For append flavor, prepend the variable's old value.
+	If the variable was previously defined recursive, set FLAVOR to
+	recursive; if it was defined simple, expand the new value before
+	appending it to the old value.  Pass RECURSIVE flag to
+	define_variable iff FLAVOR == recursive.
+
+	* variable.c (try_variable_definition): Use alloca and bcopy for
+	NAME, instead of savestring.  Might as well use stack storage

+	Always take a job off the chain and call start_waiting_job on it;
+	give up and return when start_waiting_job returns zero.
+
+	* main.c (define_makeflags: struct flag): Change member `char c' to
+	`struct command_switch *switch'.
+	(ADD_FLAG): Set that to CS instead of CS->c.
+	If CS->c is -1, increment FLAGSLEN for the long name.
+	When writing out FLAGS, handle FLAGS->switch->c == -1 and write
+	the long name instead.
+
+	* compatMakefile (stamp-config): New target of old config.h rule.
+	Touch stamp-config after running config.status.

+
+	* implicit.c (pattern_search): Check the DEP->changed flag rather

+	name arg to dir_file_exists_p to check for existence of directory.
+

+	When we find a match, record its mtime there.
+	Pass MTIME_PTR through to vpath_search to do same.

+	so globbing looks somewhere it will find things.
+
+	* compatMakefile ($(infodir)/$(instname).info): Install `make.info*'

+	with `lines_flags'.
+	(COMMANDS_{RECURSE,SILENT,NOERROR}): New macros, bits to set in
+	that flag byte.
+	* commands.c (chop_commands): Set `lines_flags' instead of
+	`lines_recurse'.  Record not only + but also @ and - prefixes.
+	* remake.c (notice_finished_file): Check the COMMANDS_RECURSE bit
+	in FILE->cmds->lines_flags, rather than FILE->cmds->lines_recurse.
+	* job.c (start_job_command): Replaced RECURSIVE and NOPRINT local
+	var with FLAGS; initialize it to the appropriate `lines_flags' byte.
+	Set CHILD->noerror if the COMMANDS_NOERROR bit is set in FLAGS.
+	Set the COMMANDS_SILENT bit in FLAGS for a @ prefix.
+
+	* remake.c (update_goal_chain): Set G->file to its prev after
+	checking for G being finished, since that check needs to examine
+	G->file.
+
+	* configure.in (union wait check) [HAVE_WAITPID]: Try using
+	waitpid with a `union wait' STATUS arg.  If waitpid and union wait
+	don't work together, we should not use union wait.
+
+	* Version 3.63.2.
+
+	* remake.c (update_goal_chain): When G->file->updated, move
+	G->file to its prev.  We aren't finished until G->file is nil.

+
+	* compatMakefile ($(bindir)/$(instname)): Put - before
+	install_setgid command line, so its failure won't be an error.
+	(infodir): New variable.
+	(install): Depend on $(infodir)/$(instname).info.
+	($(infodir)/$(instname).info): New target.
+
+	* read.c (read_makefile): If FILENAMES is nil when we see a line
+	starting with a tab, don't treat it as a command.  Just fall
+	through, rather than giving an error.
+
+	* read.c (read_makefile): If the NO_TARGETS flag is set when we see a
+	command line, don't clear it before continuing.  We want
+	subsequent command lines to be ignored as well.
+
+	* job.c (new_job): Before expanding each command line, collapse
+	backslash-newline combinations that are inside var or fn references.
+
+Mon Feb  1 16:00:13 1993  Roland McGrath  (roland@geech.gnu.ai.mit.edu)
+

+	* read.c (read_makefile): In vpath parsing, after finding the
+	pattern token, take entire rest of line as the search path, not
+	just the next token.
+
+	* compatMakefile (remote.o): Depend on remote-*.c.
+
+Thu Jan 28 16:40:29 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* commands.c (set_file_variables): Don't define any F or D versions.
+	* variable.c (define_automatic_variables): Define them here as
+	recursively-expanded variables that use the dir and notdir funcs.
+
+	* variable.c (target_environment): In v_default case, don't export
+	o_default or o_automatic variables.
+
+	* configure.in (union wait check): Remove ` and ' inside C code;
+	they confuse the shell script.
+
+Mon Jan 25 13:10:42 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* Version 3.63.1.
+
+	* vpath.c (construct_vpath_list): When skipping further processing
+	of an elt that is ".", don't also skip the code that pushes P past
+	the next separator.
+
+	* compatMakefile (distclean): Don't remove make-*.
+
+	* configure.in (HAVE_UNION_WAIT): Try to use WEXITSTATUS if it's
+	defined.  If one cannot use WEXITSTATUS with a `union wait'
+	argument, we don't want to believe the system has `union wait' at all.
+
+	* remake.c (update_file): Do nothing to print "up to date" msgs.
+	(update_goal_chain): Do it here instead.
+	Use the `changed' flag of each goal's `struct dep' to keep track
+	of whether files_remade (now commands_started) changed around a
+	call to update_file for that goal.
+	When a goal is finished, and its file's update_status is zero (i.e.,
+	success or nothing done), test the `changed' flag and give an "up
+	to date" msg iff it is clear.
+	* make.h (files_remade): Renamed to commands_started.
+	* remake.c: Changed defn.
+	(update_goal_chain): Changed uses.
+	* job.c (start_job_command): Increment commands_started here.
+	(reap_children): Not here.
+
+	* remake.c (update_goal_chain): Don't do anything with files'

+	* variable.c (target_environment): Don't expand recursive
+	variables if they came from the environment.
+
+	* main.c (define_makeflags): For flags with omitted optional args,
+	store {"", 0} with ADD_FLAG.  When constructing FLAGSTRING, a flag
+	so stored cannot have more flags appended to the same word.

+
+	* job.c [!HAVE_UNION_WAIT] (WTERMSIG, WCOREDUMP, WEXITSTATUS):
+	Don't define if already defined.
+
+	* remake.c (update_file): Don't keep track of the command_state before
+	calling update_file_1.  Remove local variable COMMANDS_FINISHED,
+	and don't test it to decide to print the "is up to date" msg.
+	Testing for files_remade having changed should always be sufficient.
+	The old method lost when we are called in the goal chain run on a
+	makefile, because the makefile's command_state is already
+	`cs_finished' from the makefile chain run.
+
+	* misc.c [HAVE_SETRE[GU]ID]: Test these to decl setre[gu]id.
+
+	* configure.in: Rewrote wait checking.
+	Use AC_HAVE_HEADERS to check for <sys/wait.h>.

+	Use a compile check to test just for `union wait'.
+	* job.c: Rewrote conditionals accordingly.
+	[HAVE_WAITPID]: Test this only to define WAIT_NOHANG.
+	[HAVE_WAIT3]: Likewise.
+	[HAVE_UNION_WAIT]: Test this to define WAIT_T and W*.
+
+	* configure.in: Set CFLAGS and LDFLAGS before all checks.
+
+	* dir.c: Add static forward decls of {open,read}_dirstream.

+
+	* compatMakefile (CFLAGS, LDFLAGS): Set to @CFLAGS@/@LDFLAGS@.

+	* configure.in: AC_SUBST(CFLAGS) and LDFLAGS.
+	Set them to -g if not defined in the environment.
+
+	* remake.c (library_search): Use LIBNAME consistently, setting it
+	only once, to be the passed name sans `-l'.
+	Pass new var FILE to be modified by vpath_search.
+
+Mon Jan 18 14:53:54 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* Version 3.62.30.

+	job_slots.
+
+	* configure.in: Add AC_CONST for the sake of getopt.
+
+	* read.c (read_makefile): Continue after parsing `override'
+	directive, rather than falling through to lossage.
+	Check for EOL or blank after "override define".
+
+	* compatMakefile (.c.o, remote.o): Put $(CFLAGS) after other switches.
+
+Fri Jan 15 12:52:52 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+
+	* Version 3.62.29.
+
+	* main.c (define_makeflags): After writing everything into
+	FLAGSTRING, only back up two chars if [-1] is a dash, meaning we
+	just wrote " -".  Always terminate the string at *P.
+
+	* remake.c (library_search): When constructing names in std dirs,
+	use &(*LIB)[2] for the stem, not LIBNAME (which points at the
+	buffer we are writing into!).
+
+Thu Jan 14 13:50:06 1993  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)
+

+
+	* main.c (die): Call print_data_base if -p.
+	(main): Don't call it here.
+
+	* compatMakefile (defines): Add @DEFS@.  configure should turn this

+	* main.c (main): Define MAKEOVERRIDES, MAKE, and MAKE_COMMAND with

+	* misc.c ({user,make}_access): Test #ifndef HAVE_SETRE[GU]ID, not

+
+	* main.c (decode_switches): Allocate ARGC slots in other_args to

+	(child_handler): Increment dead_children instead of setting child_died.
+	(reap_children): Decrement dead_children instead of clearing
+	child_died.  The point of all this is to avoid printing "waiting
+	for unfinished jobs" when we don't actually need to block.
+	This happened when multiple SIGCHLDs before reap_children was called.
+
+	* job.c (reap_children): If ERR is set, so we don't call start_job
+	on the child being reaped, instead set its command_state to
+	cs_finished.
+	(reap_children, child_handler, new_job): I added several
+	debugging printf's while fixing this.  I left them in if (debug_flag)
+	because they may be useful for debugging this stuff again.

+
+	* variable.c (target_environment): Exclude MAKELEVEL in the loop,
+	so it isn't duplicated when we add it at the end.

+Basic Installation
+==================
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+     If you're building GNU make on a system which does not already have
+     a `make', you can use the build.sh shell script to compile.  Run
+     `sh ./build.sh'.  This should compile the program in the current
+     directory.  Then you will have a Make program that you can use for
+     `make install', or whatever else.
+
+  3. Optionally, type `./make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+
+Version 3.81rc1
+
+* GNU make is ported to OS/2.
+  Port provided by Andreas Buening <andreas.buening@nexgo.de>.
+
+* All pattern-specific variables that match a given target are now used
+  (previously only the first match was used).
+
+* Target-specific variables can be marked as exportable using the
+  "export" keyword.
+
+* In a recursive $(call ...) context, any extra arguments from the outer
+  call are now masked in the context of the inner call.
+
+* Enhancements for POSIX compatibility:
+   - Only touch targets (under -t) if they have at least one command.
+
+* Updated to autoconf 2.57, automake 1.7.6, and gettext 0.12.1.  Users
+  should not be impacted.
+
+
+
+Version 3.80
+
+* A new feature exists: order-only prerequisites.  These prerequisites
+  affect the order in which targets are built, but they do not impact
+  the rebuild/no-rebuild decision of their dependents.  That is to say,
+  they allow you to require target B be built before target A, without
+  requiring that target A will always be rebuilt if target B is updated.
+  Patch for this feature provided by Greg McGary <greg@mcgary.org>.
+
+* For compatibility with SysV make, GNU make now supports the peculiar
+  syntax $$@, $$(@D), and $$(@F) in the prerequisites list of a rule.
+  This syntax is only valid within explicit and static pattern rules: it
+  cannot be used in implicit (suffix or pattern) rules.  Edouard G. Parmelan
+  <egp@free.fr> provided a patch implementing this feature; however, I
+  decided to implement it in a different way.
+
+* The argument to the "ifdef" conditional is now expanded before it's
+  tested, so it can be a constructed variable name.
+
+  Similarly, the arguments to "export" (when not used in a variable
+  definition context) and "unexport" are also now expanded.
+
+* A new function is defined: $(value ...).  The argument to this
+  function is the _name_ of a variable.  The result of the function is
+  the value of the variable, without having been expanded.
+
+* A new function is defined: $(eval ...).  The arguments to this
+  function should expand to makefile commands, which will then be
+  evaluated as if they had appeared in the makefile.  In combination
+  with define/endef multiline variable definitions this is an extremely
+  powerful capability.  The $(value ...) function is also sometimes
+  useful here.
+
+* A new built-in variable is defined, $(MAKEFILE_LIST).  It contains a
+  list of each makefile GNU make has read, or started to read, in the
+  order in which they were encountered.  So, the last filename in the
+  list when a makefile is just being read (before any includes) is the
+  name of the current makefile.
+
+* A new built-in variable is defined: $(.VARIABLES).  When it is
+  expanded it returns a complete list of variable names defined by all
+  makefiles at that moment.
+
+* A new command-line option is defined, -B or --always-make.  If
+  specified GNU make will consider all targets out-of-date even if they
+  would otherwise not be.
+
+* The arguments to $(call ...) functions were being stored in $1, $2,
+  etc. as recursive variables, even though they are fully expanded
+  before assignment.  This means that escaped dollar signs ($$ etc.)
+  were not behaving properly.  Now the arguments are stored as simple
+  variables.  This may mean that if you added extra escaping to your
+  $(call ...) function arguments you will need to undo it now.
+
+* The variable invoked by $(call ...) can now be recursive: unlike other
+  variables it can reference itself and this will not produce an error
+  when it is used as the first argument to $(call ...) (but only then).
+
+* New pseudo-target .LOW_RESOLUTION_TIME, superseding the configure
+  option --disable-nsec-timestamps.  You might need this if your build
+  process depends on tools like "cp -p" preserving time stamps, since
+  "cp -p" (right now) doesn't preserve the subsecond portion of a time
+  stamp.
+
+* Updated translations for French, Galician, German, Japanese, Korean,
+  and Russian.  New translations for Croatian, Danish, Hebrew, and
+  Turkish.
+
+* Updated internationalization support to Gettext 0.11.5.
+  GNU make now uses Gettext's "external" feature, and does not include
+  any internationalization code itself.  Configure will search your
+  system for an existing implementation of GNU Gettext (only GNU Gettext
+  is acceptable) and use it if it exists.  If not, NLS will be disabled.
+  See ABOUT-NLS for more information.
+
+* Updated to autoconf 2.54 and automake 1.7.  Users should not be impacted.
+
+
+Version 3.79.1
+
+* .SECONDARY with no prerequisites now prevents any target from being
+  removed because make thinks it's an intermediate file, not just those
+  listed in the makefile.
+
+* New configure option --disable-nsec-timestamps, but this was
+  superseded in later versions by the .LOW_RESOLUTION_TIME pseudo-target.
+
+
+Version 3.79
+
+* GNU make optionally supports internationalization and locales via the
+  GNU gettext (or local gettext if suitable) package.  See the ABOUT-NLS
+  file for more information on configuring GNU make for NLS.
+
+* Previously, GNU make quoted variables such as MAKEFLAGS and
+  MAKEOVERRIDES for proper parsing by the shell.  This allowed them to
+  be used within make build scripts.  However, using them there is not
+  proper behavior: they are meant to be passed to subshells via the
+  environment.  Unfortunately the values were not quoted properly to be
+  passed through the environment.  This meant that make didn't properly
+  pass some types of command line values to submakes.
+
+  With this version we change that behavior: now these variables are
+  quoted properly for passing through the environment, which is the
+  correct way to do it.  If you previously used these variables
+  explicitly within a make rule you may need to re-examine your use for
+  correctness given this change.
+
+* A new pseudo-target .NOTPARALLEL is available.  If defined, the
+  current makefile is run serially regardless of the value of -j.
+  However, submakes are still eligible for parallel execution.
+
+* The --debug option has changed: it now allows optional flags
+  controlling the amount and type of debugging output.  By default only
+  a minimal amount information is generated, displaying the names of
+  "normal" targets (not makefiles) that were deemed out of date and in
+  need of being rebuilt.
+
+  Note that the -d option behaves as before: it takes no arguments and
+  all debugging information is generated.
+
+* The `-p' (print database) output now includes filename and linenumber
+  information for variable definitions, to aid debugging.
+
+* The wordlist function no longer reverses its arguments if the "start"
+  value is greater than the "end" value.  If that's true, nothing is
+  returned.
+
+* Hartmut Becker provided many updates for the VMS port of GNU make.
+  See the readme.vms file for more details.
+
+
+Version 3.78
+
+* Two new functions, $(error ...) and $(warning ...) are available.  The
+  former will cause make to fail and exit immediately upon expansion of
+  the function, with the text provided as the error message.  The latter
+  causes the text provided to be printed as a warning message, but make
+  proceeds normally.
+
+* A new function $(call ...) is available.  This allows users to create
+  their own parameterized macros and invoke them later.  Original
+  implementation of this function was provided by Han-Wen Nienhuys
+  <hanwen@cs.uu.nl>.
+
+* A new function $(if ...) is available.  It provides if-then-else
+  capabilities in a builtin function.  Original implementation of this
+  function was provided by Han-Wen Nienhuys <hanwen@cs.uu.nl>.
+
+* Make defines a new variable, .LIBPATTERNS.  This variable controls how
+  library dependency expansion (dependencies like ``-lfoo'') is performed.
+
+* Make accepts CRLF sequences as well as traditional LF, for
+  compatibility with makefiles created on other operating systems.
+
+* Make accepts a new option: -R, or --no-builtin-variables.  This option
+  disables the definition of the rule-specific builtin variables (CC,
+  LD, AR, etc.).  Specifying this option forces -r (--no-builtin-rules)
+  as well.
+
+* A "job server" feature, suggested by Howard Chu <hyc@highlandsun.com>.
+
+  On systems that support POSIX pipe(2) semantics, GNU make can now pass
+  -jN options to submakes rather than forcing them all to use -j1.  The
+  top make and all its sub-make processes use a pipe to communicate with
+  each other to ensure that no more than N jobs are started across all
+  makes.  To get the old behavior of -j back, you can configure make
+  with the --disable-job-server option.
+
+* The confusing term "dependency" has been replaced by the more accurate
+  and standard term "prerequisite", both in the manual and in all GNU make
+  output.
+
+* GNU make supports the "big archive" library format introduced in AIX 4.3.
+
+* GNU make supports large files on AIX, HP-UX, and IRIX.  These changes
+  were provided by Paul Eggert <eggert@twinsun.com>.  (Large file
+  support for Solaris and Linux was introduced in 3.77, but the
+  configuration had issues: these have also been resolved).
+
+* The Windows 95/98/NT (W32) version of GNU make now has native support
+  for the Cygnus Cygwin release B20.1 shell (bash).
+
+* The GNU make regression test suite, long available separately "under
+  the table", has been integrated into the release.  You can invoke it
+  by running "make check" in the distribution.  Note that it requires
+  Perl (either Perl 4 or Perl 5) to run.
+
+
+Version 3.77
+
+* Implement BSD make's "?=" variable assignment operator.  The variable
+  is assigned the specified value only if that variable is not already
+  defined.
+
+* Make defines a new variable, "CURDIR", to contain the current working
+  directory (after the -C option, if any, has been processed).
+  Modifying this variable has no effect on the operation of make.
+
+* Make defines a new default RCS rule, for new-style master file
+  storage: ``% :: RCS/%'' (note no ``,v'' suffix).
+
+  Make defines new default rules for DOS-style C++ file naming
+  conventions, with ``.cpp'' suffixes.  All the same rules as for
+  ``.cc'' and ``.C'' suffixes are provided, along with LINK.cpp and
+  COMPILE.cpp macros (which default to the same value as LINK.cc and
+  COMPILE.cc).  Note CPPFLAGS is still C preprocessor flags!  You should
+  use CXXFLAGS to change C++ compiler flags.
+
+* A new feature, "target-specific variable values", has been added.
+  This is a large change so please see the appropriate sections of the
+  manual for full details.  Briefly, syntax like this:
+
+    TARGET: VARIABLE = VALUE
+
+  defines VARIABLE as VALUE within the context of TARGET.  This is
+  similar to SunOS make's "TARGET := VARIABLE = VALUE" feature.  Note
+  that the assignment may be of any type, not just recursive, and that
+  the override keyword is available.
+
+  COMPATIBILITY: This new syntax means that if you have any rules where
+  the first or second dependency has an equal sign (=) in its name,
+  you'll have to escape them with a backslash: "foo : bar\=baz".
+  Further, if you have any dependencies which already contain "\=",
+  you'll have to escape both of them: "foo : bar\\\=baz".
+
+* A new appendix listing the most common error and warning messages
+  generated by GNU make, with some explanation, has been added to the
+  GNU make User's Manual.
+
+* Updates to the GNU make Customs library support (see README.customs).
+
+* Updates to the Windows 95/NT port from Rob Tulloh (see README.W32),
+  and to the DOS port from Eli Zaretski (see README.DOS).
+
+
+Version 3.76.1
+
+* Small (but serious) bug fix.  Quick rollout to get into the GNU source CD.
+
+
+Version 3.76
+
+* GNU make now uses automake to control Makefile.in generation.  This
+  should make it more consistent with the GNU standards.
+
+* VPATH functionality has been changed to incorporate the VPATH+ patch,
+  previously maintained by Paul Smith <psmith@baynetworks.com>.  See the
+  manual.
+
+* Make defines a new variable, `MAKECMDGOALS', to contain the goals that
+  were specified on the command line, if any.  Modifying this variable
+  has no effect on the operation of make.
+
+* A new function, `$(wordlist S,E,TEXT)', is available: it returns a
+  list of words from number S to number E (inclusive) of TEXT.
+
+* Instead of an error, detection of future modification times gives a
+  warning and continues.  The warning is repeated just before GNU make
+  exits, so it is less likely to be lost.
+
+* Fix the $(basename) and $(suffix) functions so they only operate on
+  the last filename, not the entire string:
+
+      Command              Old Result             New Result
+      -------              ----------             ----------
+    $(basename a.b)        a                      a
+    $(basename a.b/c)      a                      a.b/c
+    $(suffix a.b)          b                      b
+    $(suffix a.b/c)        b/c                    <empty>
+
+* The $(strip) function now removes newlines as well as TABs and spaces.
+
+* The $(shell) function now changes CRLF (\r\n) pairs to a space as well
+  as newlines (\n).
+
+* Updates to the Windows 95/NT port from Rob Tulloh (see README.W32).
+
+* Eli Zaretskii has updated the port to 32-bit protected mode on MSDOS
+  and MS-Windows, building with the DJGPP v2 port of GNU C/C++ compiler
+  and utilities.  See README.DOS for details, and direct all questions
+  concerning this port to Eli Zaretskii <eliz@is.elta.co.il> or DJ
+  Delorie <dj@delorie.com>.
+
+* John W. Eaton has updated the VMS port to support libraries and VPATH.
+
+
+Version 3.75
+
+* The directory messages printed by `-w' and implicitly in sub-makes,
+  are now omitted if Make runs no commands and has no other messages to print.
+
+* Make now detects files that for whatever reason have modification times
+  in the future and gives an error.  Files with such impossible timestamps
+  can result from unsynchronized clocks, or archived distributions
+  containing bogus timestamps; they confuse Make's dependency engine
+  thoroughly.
+
+* The new directive `sinclude' is now recognized as another name for
+  `-include', for compatibility with some other Makes.
+
+* Aaron Digulla has contributed a port to AmigaDOS.  See README.Amiga for
+  details, and direct all Amiga-related questions to <digulla@fh-konstanz.de>.
+
+* Rob Tulloh of Tivoli Systems has contributed a port to Windows NT or 95.
+  See README.W32 for details, and direct all Windows-related questions to
+  <rob_tulloh@tivoli.com>.
+
+
+Version 3.73
+
+* Converted to use Autoconf version 2, so `configure' has some new options.
+  See INSTALL for details.
+
+* You can now send a SIGUSR1 signal to Make to toggle printing of debugging
+  output enabled by -d, at any time during the run.
+
+
+Version 3.72
+
+* DJ Delorie has ported Make to MS-DOS using the GO32 extender.
+  He is maintaining the DOS port, not the GNU Make maintainer;
+  please direct bugs and questions for DOS to <djgpp@sun.soe.clarkson.edu>.
+  MS-DOS binaries are available for FTP from ftp.simtel.net in
+  /pub/simtelnet/gnu/djgpp/.
+
+* The `MAKEFLAGS' variable (in the environment or in a makefile) can now
+  contain variable definitions itself; these are treated just like
+  command-line variable definitions.  Make will automatically insert any
+  variable definitions from the environment value of `MAKEFLAGS' or from
+  the command line, into the `MAKEFLAGS' value exported to children.  The
+  `MAKEOVERRIDES' variable previously included in the value of `$(MAKE)'
+  for sub-makes is now included in `MAKEFLAGS' instead.  As before, you can
+  reset `MAKEOVERRIDES' in your makefile to avoid putting all the variables
+  in the environment when its size is limited.
+
+* If `.DELETE_ON_ERROR' appears as a target, Make will delete the target of
+  a rule if it has changed when its commands exit with a nonzero status,
+  just as when the commands get a signal.
+
+* The automatic variable `$+' is new.  It lists all the dependencies like
+  `$^', but preserves duplicates listed in the makefile.  This is useful
+  for linking rules, where library files sometimes need to be listed twice
+  in the link order.
+
+* You can now specify the `.IGNORE' and `.SILENT' special targets with
+  dependencies to limit their effects to those files.  If a file appears as
+  a dependency of `.IGNORE', then errors will be ignored while running the
+  commands to update that file.  Likewise if a file appears as a dependency
+  of `.SILENT', then the commands to update that file will not be printed
+  before they are run.  (This change was made to conform to POSIX.2.)
+
+
+Version 3.71
+
+* The automatic variables `$(@D)', `$(%D)', `$(*D)', `$(<D)', `$(?D)', and
+  `$(^D)' now omit the trailing slash from the directory name.  (This change
+  was made to comply with POSIX.2.)
+
+* The source distribution now includes the Info files for the Make manual.
+  There is no longer a separate distribution containing Info and DVI files.
+
+* You can now set the variables `binprefix' and/or `manprefix' in
+  Makefile.in (or on the command line when installing) to install GNU make
+  under a name other than `make' (i.e., ``make binprefix=g install''
+  installs GNU make as `gmake').
+
+* The built-in Texinfo rules use the new variables `TEXI2DVI_FLAGS' for
+  flags to the `texi2dvi' script, and `MAKEINFO_FLAGS' for flags to the
+  Makeinfo program.
+
+* The exit status of Make when it runs into errors is now 2 instead of 1.
+  The exit status is 1 only when using -q and some target is not up to date.
+  (This change was made to comply with POSIX.2.)
+
+
+Version 3.70
+
+* It is no longer a fatal error to have a NUL character in a makefile.
+  You should never put a NUL in a makefile because it can have strange
+  results, but otherwise empty lines full of NULs (such as produced by
+  the `xmkmf' program) will always work fine.
+
+* The error messages for nonexistent included makefiles now refer to the
+  makefile name and line number where the `include' appeared, so Emacs's
+  C-x ` command takes you there (in case it's a typo you need to fix).
+
+
+Version 3.69
+
+* Implicit rule search for archive member references is now done in the
+  opposite order from previous versions: the whole target name `LIB(MEM)'
+  first, and just the member name and parentheses `(MEM)' second.
+
+* Make now gives an error for an unterminated variable or function reference.
+  For example, `$(foo' with no matching `)' or `${bar' with no matching `}'.
+
+* The new default variable `MAKE_VERSION' gives the version number of
+  Make, and a string describing the remote job support compiled in (if any).
+  Thus the value (in this release) is something like `3.69' or `3.69-Customs'.
+
+* Commands in an invocation of the `shell' function are no longer run with
+  a modified environment like target commands are.  As in versions before
+  3.68, they now run with the environment that `make' started with.  We
+  have reversed the change made in version 3.68 because it turned out to
+  cause a paradoxical situation in cases like:
+
+	export variable = $(shell echo value)
+
+  When Make attempted to put this variable in the environment for a target
+  command, it would try expand the value by running the shell command
+  `echo value'.  In version 3.68, because it constructed an environment
+  for that shell command in the same way, Make would begin to go into an
+  infinite loop and then get a fatal error when it detected the loop.
+
+* The commands given for `.DEFAULT' are now used for phony targets with no
+  commands.
+
+
+Version 3.68
+
+* You can list several archive member names inside parenthesis:
+  `lib(mem1 mem2 mem3)' is equivalent to `lib(mem1) lib(mem2) lib(mem3)'.
+
+* You can use wildcards inside archive member references.  For example,
+  `lib(*.o)' expands to all existing members of `lib' whose names end in
+  `.o' (e.g. `lib(a.o) lib(b.o)'); `*.a(*.o)' expands to all such members
+  of all existing files whose names end in `.a' (e.g. `foo.a(a.o)
+  foo.a(b.o) bar.a(c.o) bar.a(d.o)'.
+
+* A suffix rule `.X.a' now produces two pattern rules:
+	(%.o): %.X	# Previous versions produced only this.
+	%.a: %.X	# Now produces this as well, just like other suffixes.
+
+* The new flag `--warn-undefined-variables' says to issue a warning message
+  whenever Make expands a reference to an undefined variable.
+
+* The new `-include' directive is just like `include' except that there is
+  no error (not even a warning) for a nonexistent makefile.
+
+* Commands in an invocation of the `shell' function are now run with a
+  modified environment like target commands are, so you can use `export' et
+  al to set up variables for them.  They used to run with the environment
+  that `make' started with.
+
+
+Version 3.66
+
+* `make --version' (or `make -v') now exits immediately after printing
+  the version number.
+
+
+Version 3.65
+
+* Make now supports long-named members in `ar' archive files.
+
+
+Version 3.64
+
+* Make now supports the `+=' syntax for a variable definition which appends
+  to the variable's previous value.  See the section `Appending More Text
+  to Variables' in the manual for full details.
+
+* The new option `--no-print-directory' inhibits the `-w' or
+  `--print-directory' feature.  Make turns on `--print-directory'
+  automatically if you use `-C' or `--directory', and in sub-makes; some
+  users have found this behavior undesirable.
+
+* The built-in implicit rules now support the alternative extension
+  `.txinfo' for Texinfo files, just like `.texinfo' and `.texi'.
+
+
+Version 3.63
+
+* Make now uses a standard GNU `configure' script.  See the new file
+  INSTALL for the new (and much simpler) installation procedure.
+
+* There is now a shell script to build Make the first time, if you have no
+  other `make' program.  `build.sh' is created by `configure'; see README.
+
+* GNU Make now completely conforms to the POSIX.2 specification for `make'.
+
+* Elements of the `$^' and `$?' automatic variables that are archive
+  member references now list only the member name, as in Unix and POSIX.2.
+
+* You should no longer ever need to specify the `-w' switch, which prints
+  the current directory before and after Make runs.  The `-C' switch to
+  change directory, and recursive use of Make, now set `-w' automatically.
+
+* Multiple double-colon rules for the same target will no longer have their
+  commands run simultaneously under -j, as this could result in the two
+  commands trying to change the file at the same time and interfering with
+  one another.
+
+* The `SHELL' variable is now never taken from the environment.
+  Each makefile that wants a shell other than the default (/bin/sh) must
+  set SHELL itself.  SHELL is always exported to child processes.
+  This change was made for compatibility with POSIX.2.
+
+* Make now accepts long options.  There is now an informative usage message
+  that tells you what all the options are and what they do.  Try `make --help'.
+
+* There are two new directives: `export' and `unexport'.  All variables are
+  no longer automatically put into the environments of the commands that
+  Make runs.  Instead, only variables specified on the command line or in
+  the environment are exported by default.  To export others, use:
+	export VARIABLE
+  or you can define variables with:
+	export VARIABLE = VALUE
+  or:
+	export VARIABLE := VALUE
+  You can use just:
+	export
+  or:
+	.EXPORT_ALL_VARIABLES:
+  to get the old behavior.  See the node `Variables/Recursion' in the manual
+  for a full description.
+
+* The commands from the `.DEFAULT' special target are only applied to
+  targets which have no rules at all, not all targets with no commands.
+  This change was made for compatibility with Unix make.
+
+* All fatal error messages now contain `***', so they are easy to find in
+  compilation logs.
+
+* Dependency file names like `-lNAME' are now replaced with the actual file
+  name found, as with files found by normal directory search (VPATH).
+  The library file `libNAME.a' may now be found in the current directory,
+  which is checked before VPATH; the standard set of directories (/lib,
+  /usr/lib, /usr/local/lib) is now checked last.
+  See the node `Libraries/Search' in the manual for full details.
+
+* A single `include' directive can now specify more than one makefile to
+  include, like this:
+	include file1 file2
+  You can also use shell file name patterns in an `include' directive:
+	include *.mk
+
+* The default directories to search for included makefiles, and for
+  libraries specified with `-lNAME', are now set by configuration.
+
+* You can now use blanks as well as colons to separate the directories in a
+  search path for the `vpath' directive or the `VPATH' variable.
+
+* You can now use variables and functions in the left hand side of a
+  variable assignment, as in "$(foo)bar = value".
+
+* The `MAKE' variable is always defined as `$(MAKE_COMMAND) $(MAKEOVERRIDES)'.
+  The `MAKE_COMMAND' variable is now defined to the name with which make
+  was invoked.
+
+* The built-in rules for C++ compilation now use the variables `$(CXX)' and
+  `$(CXXFLAGS)' instead of `$(C++)' and `$(C++FLAGS)'.  The old names had
+  problems with shells that cannot have `+' in environment variable names.
+
+* The value of a recursively expanded variable is now expanded when putting
+  it into the environment for child processes.  This change was made for
+  compatibility with Unix make.
+
+* A rule with no targets before the `:' is now accepted and ignored.
+  This change was made for compatibility with SunOS 4 make.
+  We do not recommend that you write your makefiles to take advantage of this.
+
+* The `-I' switch can now be used in MAKEFLAGS, and are put there
+  automatically just like other switches.
+
+
+Version 3.61
+
+* Built-in rules for C++ source files with the `.C' suffix.
+  We still recommend that you use `.cc' instead.
+
+* If commands are given too many times for a single target,
+  the last set given is used, and a warning message is printed.
+
+* Error messages about makefiles are in standard GNU error format,
+  so C-x ` in Emacs works on them.
+
+* Dependencies of pattern rules which contain no % need not actually exist
+  if they can be created (just like dependencies which do have a %).
+
+
+Version 3.60
+
+* A message is always printed when Make decides there is nothing to be done.
+  It used to be that no message was printed for top-level phony targets
+  (because "`phony' is up to date" isn't quite right).  Now a different
+  message "Nothing to be done for `phony'" is printed in that case.
+
+* Archives on AIX now supposedly work.
+
+* When the commands specified for .DEFAULT are used to update a target,
+  the $< automatic variable is given the same value as $@ for that target.
+  This is how Unix make behaves, and this behavior is mandated by POSIX.2.
+
+
+Version 3.59
+
+* The -n, -q, and -t options are not put in the `MAKEFLAGS' and `MFLAG'
+  variables while remaking makefiles, so recursive makes done while remaking
+  makefiles will behave properly.
+
+* If the special target `.NOEXPORT' is specified in a makefile,
+  only variables that came from the environment and variables
+  defined on the command line are exported.
+
+
+Version 3.58
+
+* Suffix rules may have dependencies (which are ignored).
+
+
+Version 3.57
+
+* Dependencies of the form `-lLIB' are searched for as /usr/local/lib/libLIB.a
+  as well as libLIB.a in /usr/lib, /lib, the current directory, and VPATH.
+
+
+Version 3.55
+
+* There is now a Unix man page for GNU Make.  It is certainly not a replacement
+for the Texinfo manual, but it documents the basic functionality and the
+switches.  For full documentation, you should still read the Texinfo manual.
+Thanks to Dennis Morse of Stanford University for contributing the initial
+version of this.
+
+* Variables which are defined by default (e.g., `CC') will no longer be put
+into the environment for child processes.  (If these variables are reset by the
+environment, makefiles, or the command line, they will still go into the
+environment.)
+
+* Makefiles which have commands but no dependencies (and thus are always
+  considered out of date and in need of remaking), will not be remade (if they
+  were being remade only because they were makefiles).  This means that GNU
+  Make will no longer go into an infinite loop when fed the makefiles that
+  `imake' (necessary to build X Windows) produces.
+
+* There is no longer a warning for using the `vpath' directive with an explicit
+pathname (instead of a `%' pattern).
+
+
+Version 3.51
+
+* When removing intermediate files, only one `rm' command line is printed,
+listing all file names.
+
+* There are now automatic variables `$(^D)', `$(^F)', `$(?D)', and `$(?F)'.
+These are the directory-only and file-only versions of `$^' and `$?'.
+
+* Library dependencies given as `-lNAME' will use "libNAME.a" in the current
+directory if it exists.
+
+* The automatic variable `$($/)' is no longer defined.
+
+* Leading `+' characters on a command line make that line be executed even
+under -n, -t, or -q (as if the line contained `$(MAKE)').
+
+* For command lines containing `$(MAKE)', `${MAKE}', or leading `+' characters,
+only those lines are executed, not their entire rules.
+(This is how Unix make behaves for lines containing `$(MAKE)' or `${MAKE}'.)
+
+
+Version 3.50
+
+* Filenames in rules will now have ~ and ~USER expanded.
+
+* The `-p' output has been changed so it can be used as a makefile.
+(All information that isn't specified by makefiles is prefaced with comment
+characters.)
+
+
+Version 3.49
+
+* The % character can be quoted with backslash in implicit pattern rules,
+static pattern rules, `vpath' directives, and `patsubst', `filter', and
+`filter-out' functions.  A warning is issued if a `vpath' directive's
+pattern contains no %.
+
+* The `wildcard' variable expansion function now expands ~ and ~USER.
+
+* Messages indicating failed commands now contain the target name:
+	make: *** [target] Error 1
+
+* The `-p' output format has been changed somewhat to look more like
+makefile rules and to give all information that Make has about files.
+
+
+Version 3.48
+
+
+Version 3.47
+
+* The `-l' switch with no argument removes any previous load-average limit.
+
+* When the `-w' switch is in effect, and Make has updated makefiles,
+it will write a `Leaving directory' messagfe before re-executing itself.
+This makes the `directory change tracking' changes to Emacs's compilation
+commands work properly.
+
+
+Version 3.46
+
+* The automatic variable `$*' is now defined for explicit rules,
+as it is in Unix make.
+
+
+Version 3.45
+
+* The `-j' switch is now put in the MAKEFLAGS and MFLAGS variables when
+specified without an argument (indicating infinite jobs).
+The `-l' switch is not always put in the MAKEFLAGS and MFLAGS variables.
+
+* Make no longer checks hashed directories after running commands.
+The behavior implemented in 3.41 caused too much slowdown.
+
+
+Version 3.44
+
+* A dependency is NOT considered newer than its dependent if
+they have the same modification time.  The behavior implemented
+in 3.43 conflicts with RCS.
+
+
+Version 3.43
+
+* Dependency loops are no longer fatal errors.
+
+* A dependency is considered newer than its dependent if
+they have the same modification time.
+
+
+Version 3.42
+
+* The variables F77 and F77FLAGS are now set by default to $(FC) and
+$(FFLAGS).  Makefiles designed for System V make may use these variables in
+explicit rules and expect them to be set.  Unfortunately, there is no way to
+make setting these affect the Fortran implicit rules unless FC and FFLAGS
+are not used (and these are used by BSD make).
+
+
+Version 3.41
+
+* Make now checks to see if its hashed directories are changed by commands.
+Other makes that hash directories (Sun, 4.3 BSD) don't do this.
+
+
+Version 3.39
+
+* The `shell' function no longer captures standard error output.
+
+
+Version 3.32
+
+* A file beginning with a dot can be the default target if it also contains
+a slash (e.g., `../bin/foo').  (Unix make allows this as well.)
+
+
+Version 3.31
+
+* Archive member names are truncated to 15 characters.
+
+* Yet more USG stuff.
+
+* Minimal support for Microport System V (a 16-bit machine and a
+brain-damaged compiler).  This has even lower priority than other USG
+support, so if it gets beyond trivial, I will take it out completely.
+
+* Revamped default implicit rules (not much visible change).
+
+* The -d and -p options can come from the environment.
+
+
+Version 3.30
+
+* Improved support for USG and HPUX (hopefully).
+
+* A variable reference like `$(foo:a=b)', if `a' contains a `%', is
+equivalent to `$(patsubst a,b,$(foo))'.
+
+* Defining .DEFAULT with no deps or commands clears its commands.
+
+* New default implicit rules for .S (cpp, then as), and .sh (copy and make
+executable).  All default implicit rules that use cpp (even indirectly), use
+$(CPPFLAGS).
+
+
+Version 3.29
+
+* Giving the -j option with no arguments gives you infinite jobs.
+
+
+Version 3.28
+
+* New option: "-l LOAD" says not to start any new jobs while others are
+running if the load average is not below LOAD (a floating-point number).
+
+* There is support in place for implementations of remote command execution
+in Make.  See the file remote.c.
+
+
+Version 3.26
+
+* No more than 10 directories will be kept open at once.
+(This number can be changed by redefining MAX_OPEN_DIRECTORIES in dir.c.)
+
+
+Version 3.25
+
+* Archive files will have their modification times recorded before doing
+anything that might change their modification times by updating an archive
+member.
+
+
+Version 3.20
+
+* The `MAKELEVEL' variable is defined for use by makefiles.
+
+
+Version 3.19
+
+* The recursion level indications in error messages are much shorter than
+they were in version 3.14.
+
+
+Version 3.18
+
+* Leading spaces before directives are ignored (as documented).
+
+* Included makefiles can determine the default goal target.
+(System V Make does it this way, so we are being compatible).
+
+
+Version 3.14.
+
+* Variables that are defaults built into Make will not be put in the
+environment for children.  This just saves some environment space and,
+except under -e, will be transparent to sub-makes.
+
+* Error messages from sub-makes will indicate the level of recursion.
+
+* Hopefully some speed-up for large directories due to a change in the
+directory hashing scheme.
+
+* One child will always get a standard input that is usable.
+
+* Default makefiles that don't exist will be remade and read in.
+
+
+Version 3.13.
+
+* Count parentheses inside expansion function calls so you can
+have nested calls: `$(sort $(foreach x,a b,$(x)))'.
+
+
+Version 3.12.
+
+* Several bug fixes, including USG and Sun386i support.
+
+* `shell' function to expand shell commands a la `
+
+* If the `-d' flag is given, version information will be printed.
+
+* The `-c' option has been renamed to `-C' for compatibility with tar.
+
+* The `-p' option no longer inhibits other normal operation.
+
+* Makefiles will be updated and re-read if necessary.
+
+* Can now run several commands at once (parallelism), -j option.
+
+* Error messages will contain the level of Make recursion, if any.
+
+* The `MAKEFLAGS' and `MFLAGS' variables will be scanned for options after
+makefiles are read.
+
+* A double-colon rule with no dependencies will always have its commands run.
+(This is how both the BSD and System V versions of Make do it.)
+
+
+Version 3.05
+
+(Changes from versions 1 through 3.05 were never recorded.  Sorry.)

+Short: Port of GNU make with SAS/C (no ixemul.library required)
+Author: GNU, Amiga port by Aaron "Optimizer" Digulla
+Uploader: Aaron "Optimizer" Digulla (digulla@fh-konstanz.de)
+Type: dev/c
+
+This is a pure Amiga port of GNU make. It needs no extra libraries or
+anything. It has the following features (in addition to any features of
+GNU make):
+
+- Runs Amiga-Commands with SystemTags() (Execute)
+- Can run multi-line statements
+- Allows to use Device-Names in targets:
+
+	c:make : make.o
+
+    is ok. To distinguish between device-names and target : or ::, MAKE
+    looks for spaces. If there are any around :, it's taken as a target
+    delimiter, if there are none, it's taken as the name of a device. Note
+    that "make:make.o" tries to create "make.o" on the device "make:".
+- Replaces @@ by a newline in any command line:
+
+	if exists make @@\
+	    delete make.bak quiet @@\
+	    rename make make.bak @@\
+	endif @@\
+	$(CC) Link Make.o To make
+
+    works. Note that the @@ must stand alone (ie. "make@@\" is illegal).
+    Also be carefull that there is a space after the "\" (ie, at the
+    beginning of the next line).
+- Can be made resident to save space and time
+- Amiga specific wildcards can be used in $(wildcard ...)
+
+BUGS:
+- The line
+
+    dummy.h : src/*.c
+
+tries to make dummy.h from "src/*.c" (ie. no wildcard-expansion takes
+place). You have to use "$(wildcard src/*.c)" instead.
+
+COMPILING FROM SCRATCH
+----------------------
+
+To recompile, you need SAS/C 6.51. make itself is not neccessary, there
+is an smakefile.
+
+1. Copy config.ami to config.h
+2. If you use make to compie, copy Makefile.ami to Makefile and
+    glob/Makefile.ami to glob/Makefile. Copy make into the current
+    directory.
+
+3. Run smake/make
+
+INSTALLATION
+
+Copy make somewhere in your search path (eg. sc:c or sc:bin).
+If you plan to use recursive makes, install make resident:
+
+    Resident make Add

+Port of GNU Make to 32-bit protected mode on MSDOS and MS-Windows.
+
+Builds with DJGPP v2 port of GNU C/C++ compiler and utilities.
+
+
+New (since 3.74) DOS-specific features:
+
+   1. Supports long filenames when run from DOS box on Windows 9x.
+
+   2. Supports both stock DOS COMMAND.COM and Unix-style shells
+      (details in ``Notes'' below).
+
+   3. Supports DOS drive letters in dependencies and pattern rules.
+
+   4. Better support for DOS-style backslashes in pathnames (but see
+      ``Notes'' below).
+
+   5. The $(shell) built-in can run arbitrary complex commands,
+      including pipes and redirection, even when COMMAND.COM is your
+      shell.
+
+   6. Can be built without floating-point code (see below).
+
+   7. Supports signals in child programs and restores the original
+      directory if the child was interrupted.
+
+   8. Can be built without (a previous version of) Make.
+
+   9. The build process requires only standard tools.  (Optional
+      targets like "install:" and "clean:" still need additional
+      programs, though, see below.)
+
+  10. Beginning with v3.78, the test suite works in the DJGPP
+      environment (requires Perl and auxiliary tools; see below).
+
+
+To install a binary distribution:
+
+   Simply unzip the makNNNb.zip file (where NNN is the version number)
+   preserving the directory structure (-d switch if you use PKUNZIP).
+   If you are installing Make on Windows 9X or Windows 2000, use an
+   unzip program that supports long filenames in zip files.  After
+   unzipping, make sure the directory with make.exe is on your PATH,
+   and that's all you need to use Make.
+
+
+To build from sources:
+
+   1. Unzip the archive, preserving the directory structure (-d switch
+      if you use PKUNZIP).  If you build Make on Windows 9X or Windows
+      2000, use an unzip program that supports long filenames in zip
+      files.
+
+      If you are unpacking an official GNU source distribution, use
+      either DJTAR (which is part of the DJGPP development
+      environment), or the DJGPP port of GNU Tar.
+
+   2. Invoke the `configure.bat' batch file.
+
+      If you are building Make in-place, i.e. in the same directory
+      where its sources are kept, just type "configure.bat" and press
+      [Enter].  Otherwise, you need to supply the path to the source
+      directory as an argument to the batch file, like this:
+
+	c:\djgpp\gnu\make-%VERSION%\configure.bat c:/djgpp/gnu/make-%VERSION%
+
+      Note the forward slashes in the source path argument: you MUST
+      use them here.
+
+   3. If configure.bat doesn't find a working Make, it will suggest to
+      use the `dosbuild.bat' batch file to build Make.  Either do as it
+      suggests or install another Make program (a pre-compiled binary
+      should be available from the usual DJGPP sites) and rerun
+      configure.bat.
+
+   4. If you will need to run Make on machines without an FPU, you
+      might consider building a version of Make which doesn't issue
+      floating-point instructions (they don't help much on MSDOS
+      anyway).  To this end, edit the Makefile created by
+      configure.bat and add -DNO_FLOAT to the value of CPPFLAGS.
+
+   5. Invoke Make.
+
+      If you are building from outside of the source directory, you
+      need to tell Make where the sources are, like this:
+
+	        make srcdir=c:/djgpp/gnu/make-%VERSION%
+
+      (configure.bat will tell you this when it finishes).  You MUST
+      use a full, not relative, name of the source directory here, or
+      else Make might fail.
+
+   6. After Make finishes, if you have a Unix-style shell installed,
+      you can use the `install' target to install the package.  You
+      will also need GNU Fileutils and GNU Sed for this (they should
+      be available from the DJGPP sites).
+
+      By default, GNU make will install into your DJGPP installation
+      area.  If you wish to use a different directory, override the
+      DESTDIR variable when invoking "make install", like this:
+
+		make install DESTDIR=c:/other/dir
+
+      This causes the make executable to be placed in c:/other/dir/bin,
+      the man pages in c:/other/dir/man, etc.
+
+      Without a Unix-style shell, you will have to install programs
+      and the docs manually.  Copy make.exe to a directory on your
+      PATH, make.i* info files to your Info directory, and update the
+      file `dir' in your Info directory by adding the following item
+      to the main menu:
+
+	* Make: (make.info).           The GNU make utility.
+
+      If you have the `install-info' program (from the GNU Texinfo
+      package), it will do that for you if you invoke it like this:
+
+	install-info --info-dir=c:/djgpp/info c:/djgpp/info/make.info
+
+      (If your Info directory is other than C:\DJGPP\INFO, change this
+      command accordingly.)
+
+   7. The `clean' targets also require Unix-style shell, and GNU Sed
+      and `rm' programs (the latter from Fileutils).
+
+   8. To run the test suite, type "make check".  This requires a Unix
+      shell (I used the DJGPP port of Bash 2.03), Perl, Sed, Fileutils
+      and Sh-utils.
+
+
+Notes:
+-----
+
+   1. The shell issue.
+
+      This is probably the most significant improvement, first
+      introduced in the port of GNU Make 3.75.
+
+      The original behavior of GNU Make is to invoke commands
+      directly, as long as they don't include characters special to
+      the shell or internal shell commands, because that is faster.
+      When shell features like redirection or filename wildcards are
+      involved, Make calls the shell.
+
+      This port supports both DOS shells (the stock COMMAND.COM and its
+      4DOS/NDOS replacements), and Unix-style shells (tested with the
+      venerable Stewartson's `ms_sh' 2.3 and the DJGPP port of `bash' by
+      Daisuke Aoyama <jack@st.rim.or.jp>).
+
+      When the $SHELL variable points to a Unix-style shell, Make
+      works just like you'd expect on Unix, calling the shell for any
+      command that involves characters special to the shell or
+      internal shell commands.  The only difference is that, since
+      there is no standard way to pass command lines longer than the
+      infamous DOS 126-character limit, this port of Make writes the
+      command line to a temporary disk file and then invokes the shell
+      on that file.
+
+      If $SHELL points to a DOS-style shell, however, Make will not
+      call it automatically, as it does with Unix shells.  Stock
+      COMMAND.COM is too dumb and would unnecessarily limit the
+      functionality of Make.  For example, you would not be able to
+      use long command lines in commands that use redirection or
+      pipes.  Therefore, when presented with a DOS shell, this port of
+      Make will emulate most of the shell functionality, like
+      redirection and pipes, and shall only call the shell when a
+      batch file or a command internal to the shell is invoked.  (Even
+      when a command is an internal shell command, Make will first
+      search the $PATH for it, so that if a Makefile calls `mkdir',
+      you can install, say, a port of GNU `mkdir' and have it called
+      in that case.)
+
+      The key to all this is the extended functionality of `spawn' and
+      `system' functions from the DJGPP library; this port just calls
+      `system' where it would invoke the shell on Unix.  The most
+      important aspect of these functions is that they use a special
+      mechanism to pass long (up to 16KB) command lines to DJGPP
+      programs.  In addition, `system' emulates some internal
+      commands, like `cd' (so that you can now use forward slashes
+      with it, and can also change the drive if the directory is on
+      another drive).  Another aspect worth mentioning is that you can
+      call Unix shell scripts directly, provided that the shell whose
+      name is mentioned on the first line of the script is installed
+      anywhere along the $PATH.  It is impossible to tell here
+      everything about these functions; refer to the DJGPP library
+      reference for more details.
+
+      The $(shell) built-in is implemented in this port by calling
+      `popen'.  Since `popen' calls `system', the above considerations
+      are valid for $(shell) as well.  In particular, you can put
+      arbitrary complex commands, including pipes and redirection,
+      inside $(shell), which is in many cases a valid substitute for
+      the Unix-style command substitution (`command`) feature.
+
+
+   2. "SHELL=/bin/sh" -- or is it?
+
+      Many Unix Makefiles include a line which sets the SHELL, for
+      those versions of Make which don't have this as the default.
+      Since many DOS systems don't have `sh' installed (in fact, most
+      of them don't even have a `/bin' directory), this port takes
+      such directives with a grain of salt.  It will only honor such a
+      directive if the basename of the shell name (like `sh' in the
+      above example) can indeed be found in the directory that is
+      mentioned in the SHELL= line (`/bin' in the above example), or
+      in the current working directory, or anywhere on the $PATH (in
+      that order).  If the basename doesn't include a filename
+      extension, Make will look for any known extension that indicates
+      an executable file (.exe, .com, .bat, .btm, .sh, and even .sed
+      and .pl).  If any such file is found, then $SHELL will be
+      defined to the exact pathname of that file, and that shell will
+      hence be used for the rest of processing.  But if the named
+      shell is *not* found, the line which sets it will be effectively
+      ignored, leaving the value of $SHELL as it was before.  Since a
+      lot of decisions that this port makes depend on the gender of
+      the shell, I feel it doesn't make any sense to tailor Make's
+      behavior to a shell which is nowhere to be found.
+
+      Note that the above special handling of "SHELL=" only happens
+      for Makefiles; if you set $SHELL in the environment or on the
+      Make command line, you are expected to give the complete
+      pathname of the shell, including the filename extension.
+
+      The default value of $SHELL is computed as on Unix (see the Make
+      manual for details), except that if $SHELL is not defined in the
+      environment, $COMSPEC is used.  Also, if an environment variable
+      named $MAKESHELL is defined, it takes precedence over both
+      $COMSPEC and $SHELL.  Note that, unlike Unix, $SHELL in the
+      environment *is* used to set the shell (since on MSDOS, it's
+      unlikely that the interactive shell will not be suitable for
+      Makefile processing).
+
+      The bottom line is that you can now write Makefiles where some
+      of the targets require a real (i.e. Unix-like) shell, which will
+      nevertheless work when such shell is not available (provided, of
+      course, that the commands which should always work, don't
+      require such a shell).  More important, you can convert Unix
+      Makefiles to MSDOS and leave the line which sets the shell
+      intact, so that people who do have Unixy shell could use it for
+      targets which aren't converted to DOS (like `install' and
+      `uninstall', for example).
+
+
+   3. Default directories.
+
+      GNU Make knows about standard directories where it searches for
+      library and include files mentioned in the Makefile.  Since
+      MSDOS machines don't have standard places for these, this port
+      will search ${DJDIR}/lib and ${DJDIR}/include respectively.
+      $DJDIR is defined automatically by the DJGPP startup code as the
+      root of the DJGPP installation tree (unless you've tampered with
+      the DJGPP.ENV file).  This should provide reasonable default
+      values, unless you moved parts of DJGPP to other directories.
+
+
+   4. Letter-case in filenames.
+
+      If you run Make on Windows 9x, you should be aware of the
+      letter-case issue.  Make is internally case-sensitive, but all
+      file operations are case-insensitive on Windows 9x, so
+      e.g. files `FAQ', `faq' and `Faq' all refer to the same file, as
+      far as Windows is concerned.  The underlying DJGPP C library
+      functions honor the letter-case of the filenames they get from
+      the OS, except that by default, they down-case 8+3 DOS filenames
+      which are stored in upper case in the directory and would break
+      many Makefiles otherwise.  (The details of which filenames are
+      converted to lower case are explained in the DJGPP libc docs,
+      under the `_preserve_fncase' and `_lfn_gen_short_fname'
+      functions, but as a thumb rule, any filename that is stored in
+      upper case in the directory, is a valid DOS 8+3 filename and
+      doesn't include characters invalid on MSDOS FAT filesystems,
+      will be automatically down-cased.)  User reports that I have
+      indicate that this default behavior is generally what you'd
+      expect; however, your input is most welcome.
+
+      In any case, if you hit a situation where you must force Make to
+      get the 8+3 DOS filenames in upper case, set FNCASE=y in the
+      environment or in the Makefile.
+
+
+   5. DOS-style pathnames.
+
+      There are a lot of places throughout the program sources which
+      make implicit assumptions about the pathname syntax.  In
+      particular, the directories are assumed to be separated by `/',
+      and any pathname which doesn't begin with a `/' is assumed to be
+      relative to the current directory.  This port attempts to
+      support DOS-style pathnames which might include the drive letter
+      and use backslashes instead of forward slashes.  However, this
+      support is not complete; I feel that pursuing this support too
+      far might break some more important features, particularly if
+      you use a Unix-style shell (where a backslash is a quote
+      character).  I only consider support of backslashes desirable
+      because some Makefiles invoke non-DJGPP programs which don't
+      understand forward slashes.  A notable example of such programs
+      is the standard programs which come with MSDOS.  Otherwise, you
+      are advised to stay away from backslashes whenever possible.  In
+      particular, filename globbing won't work on pathnames with
+      backslashes, because the GNU `glob' library doesn't support them
+      (backslash is special in filename wildcards, and I didn't want
+      to break that).
+
+      One feature which *does* work with backslashes is the filename-
+      related built-in functions such as $(dir), $(notdir), etc.
+      Drive letters in pathnames are also fully supported.
+
+
+
+Bug reports:
+-----------
+
+   Bugs that are clearly related to the MSDOS/DJGPP port should be
+   reported first on the comp.os.msdos.djgpp news group (if you cannot
+   post to Usenet groups, write to the DJGPP mailing list,
+   <djgpp@delorie.com>, which is an email gateway into the above news
+   group).  For other bugs, please follow the procedure explained in
+   the "Bugs" chapter of the Info docs.  If you don't have an Info
+   reader, look up that chapter in the `make.i1' file with any text
+   browser/editor.
+
+
+   Enjoy,

+Port of GNU make to OS/2.
+
+Features of GNU make that do not work under OS/2:
+  - remote job execution
+  - dynamic load balancing
+
+
+Special features of the OS/2 version:
+
+Due to the fact that some people might want to use sh syntax in
+Makefiles while others might want to use OS/2's native shell cmd.exe,
+GNU make supports both shell types. The following list defines the order
+that is used to determine the shell:
+
+ 1. The shell specified by the environment variable MAKESHELL.
+ 2. The shell specified by the SHELL variable within a Makefile. As on
+    Unix, SHELL is NOT taken from the environment.
+ 3. The shell specified by the COMSPEC environment variable.
+ 4. The shell specified by the OS2_SHELL environment variable.
+ 5. If none of the above is defined /bin/sh is used as default.  This
+    happens e.g. in the make testsuite.
+
+Note: - Points 3 and 4 can be turned off at compile time by adding
+        -DNO_CMD_DEFAULT to the CPPFLAGS.
+      - DOS support is not tested for EMX and therefore might not work.
+      - The UNIXROOT environment variable is supported to find /bin/sh
+        if it is not on the current drive.
+
+
+COMPILATION OF GNU MAKE FOR OS/2:
+
+I. ***** SPECIAL OPTIONS *****
+
+ - At compile time you can turn off that cmd is used as default shell
+   (but only /bin/sh). Simply set CPPFLAGS="-DNO_CMD_DEFAULT" and make
+   will not use cmd unless you cause it to do so by setting MAKESHELL to
+   cmd or by specifying SHELL=cmd in your Makefile.
+
+ - At compile time you can set CPPFLAGS="-DNO_CHDIR2" to turn off that
+   GNU make prints drive letters. This is necessary if you want to run
+   the testsuite.
+
+
+II. ***** REQUIREMENTS FOR THE COMPILATION *****
+
+A standard Unix like build environment:
+
+ - sh compatible shell (ksh, bash, ash, but tested only with pdksh 5.2.14
+   (release 2)
+   If you use pdksh it is recommended to update to 5.2.14 release 2. Older
+   versions may not work! You can get this version at
+   http://www.math.ohio-state.edu/~ilya/software/os2/pdksh-5.2.14-bin-2.zip
+ - GNU file utilities (make sure that install.exe from the file utilities
+   is in front of your PATH before X:\OS2\INSTALL\INSTALL.EXE. I recommend
+   also to change the filename to ginstall.exe instead of install.exe
+   to avoid confusion with X:\OS2\INSTALL\INSTALL.EXE)
+ - GNU shell utilities
+ - GNU text utilities
+ - gawk
+ - grep
+ - sed
+ - GNU make 3.79.1 (special OS/2 patched version)
+ - perl 5.005 or higher
+ - GNU texinfo (you can use 3.1 (gnuinfo.zip), but I recommend 4.0)
+
+If you want to recreate the configuration files (developers only!)
+you need also: GNU m4 1.4, autoconf 2.57, automake 1.7.2 (or compatible)
+
+
+III. ***** COMPILATION AND INSTALLATION *****
+
+ a) ** Developers only - Everyone else should skip this section **
+    To recreate the configuration files use:
+
+      export EMXSHELL=ksh
+      aclocal -I config
+      automake
+      autoconf
+      autoheader
+
+
+b) Installation into x:/usr
+
+   Note: Although it is possible to compile make using "./configure",
+         "make", "make install" this is not recommended.  In particular,
+         you must ALWAYS use LDFLAGS="-Zstack 0x8000" because the default
+         stack size is far to small and make will not work properly!
+
+Recommended environment variables and installation options:
+
+    export ac_executable_extensions=".exe"
+    export CPPFLAGS="-D__ST_MT_ERRNO__"
+    export CFLAGS="-O2 -Zomf -Zmt"
+    export LDFLAGS="-Zcrtdll -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x8000"
+    export RANLIB="echo"
+    ./configure --prefix=x:/usr --infodir=x:/usr/share/info --mandir=x:/usr/share/man --without-included-gettext
+    make AR=emxomfar
+    make install
+
+Note: If you use gcc 2.9.x or higher I recommend to set also LIBS="-lgcc"
+
+Note: You can add -DNO_CMD_DEFAULT and -DNO_CHDIR2 to CPPFLAGS.
+      See section I. for details.
+
+
+IV. ***** NLS support *****
+
+GNU make has NLS (National Language Support), with the following
+caveats:
+
+ a) It will only work with GNU gettext, and
+ b) GNU gettext support is not included in the GNU make package.
+
+Therefore, if you wish to enable the internationalization features of
+GNU make you must install GNU gettext on your system before configuring
+GNU make.
+
+You can choose the languages to be installed. To install support for
+English, German and French only enter:
+
+  export LINGUAS="en de fr"
+
+If you don't specify LINGUAS all languages are installed.
+
+If you don't want NLS support (English only) use the option
+--disable-nls for the configure script.  Note if GNU gettext is not
+installed then NLS will not be enabled regardless of this flag.
+
+
+V. ***** Running the make test suite *****
+
+To run the included make test suite you have to set
+
+  CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
+
+before you compile make. This is due to some restrictions of the
+testsuite itself. -DNO_CMD_DEFAULT causes make to use /bin/sh as default
+shell in every case. Normally you could simply set MAKESHELL="/bin/sh"
+to do this but the testsuite ignores the environment. -DNO_CHDIR2 causes
+make not to use drive letters for directory names (i.e. _chdir2() and
+_getcwd2() are NOT used).  The testsuite interpretes the whole output of
+make, especially statements like make[1]: Entering directory
+`C:/somewhere/make-3.79.1/tests' where the testsuite does not expect the
+drive letter. This would be interpreted as an error even if there is
+none.
+
+To run the testsuite do the following:
+
+  export CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
+  export CFLAGS="-Zomf -O2 -s -Zmt"
+  export LDFLAGS="-Zcrtdll -Zmt -s -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x8000"
+  export RANLIB="echo"
+  ./configure --prefix=x:/usr --disable-nls
+  make AR=emxomfar
+  make checks
+
+All tests should work fine with the exception of "default_names" which
+is because OS/2 file systems are not case sensitive ("makefile" and
+"Makefile" specify the same file).

+Port of GNU make to Windows NT and Windows 95
+Builds natively with MSVC 2.x or MSVC 4.x compilers.
+Should also build fine with MSVC 5.x and 6.x (though not confirmed).
+
+This Windows 32-bit port of GNU make is maintained primarily by Rob
+Tulloh, who is also the author of this README.
+
+To build with nmake on Windows NT, Windows 95, or Windows 98:
+
+	1. Make sure cl.exe is in your %Path%. Example:
+
+		set Path=%Path%;c:/msdev/bin
+
+	2. Make sure %include% is set to msvc include directory. Example:
+
+		set include=c:/msdev/include
+
+	3. Make sure %lib% is set to msvc lib directory. Example:
+
+		set lib=c:/msdev/lib
+
+	4. nmake /f NMakefile
+
+
+    A short cut to steps 1, 2, and 3 is to run VCVARS32.bat before
+    invoking namke. For example:
+
+        c:
+        cd \msdev\bin
+        VCVARS32.bat
+	cd \path\to\make-%VERSION%
+	nmake /f NMakefile
+
+There is a bat file (build_w32.bat) for folks who have fear of nmake.
+
+Outputs:
+
+	WinDebug/make.exe
+	WinRel/make.exe
+
+
+-- Notes/Caveats --
+
+GNU make on Windows 32-bit platforms:
+
+	This version of make is ported natively to Windows32 platforms
+	(Windows NT 3.51, Windows NT 4.0, Windows 95, and Windows 98). It
+	does not rely on any 3rd party software or add-on packages for
+	building. The only thing needed is a version of Visual C++,
+	which is the predominant compiler used on Windows32 platforms.
+
+	Do not confuse this port of GNU make with other Windows32 projects
+	which provide a GNU make binary. These are separate projects
+	and are not connected to this port effort.
+
+GNU make and sh.exe:
+
+	This port prefers you have a working sh.exe somewhere on your
+	system. If you don't have sh.exe, the port falls back to
+	MSDOS mode for launching programs (via a batch file).
+	The MSDOS mode style execution has not been tested that
+	carefully though (The author uses GNU bash as sh.exe).
+
+	There are very few true ports of Bourne shell for NT right now.
+	There is a version of GNU bash available from Cygnus "Cygwin"
+	porting effort (http://sourceware.cygnus.com/cygwin).
+	Other possibilities are the MKS version of sh.exe, or building
+        your own with a package like NutCracker (DataFocus) or Portage
+        (Consensys).
+
+GNU make and brain-dead shells (BATCH_MODE_ONLY_SHELL):
+
+	Some versions of Bourne shell does not behave well when invoked
+	as 'sh -c' from CreateProcess().  The main problem is they seem
+	to have a hard time handling quoted strings correctly. This can
+	be circumvented by writing commands to be executed to a batch
+	file and then executing the command by calling 'sh file'.
+
+	To work around this difficulty, this version of make supports
+	a batch mode.  When BATCH_MODE_ONLY_SHELL is defined at compile
+	time, make forces all command lines to be executed via script
+	files instead of by command line.
+
+	A native Windows32 system with no Bourne shell will also run
+	in batch mode.  All command lines will be put into batch files
+	and executed via $(COMSPEC) (%COMSPEC%).
+
+GNU make and Cygnus GNU Windows32 tools:
+
+	Good news! Make now has native support for Cygwin sh. To enable,
+	define the HAVE_CYGWIN_SHELL in config.h and rebuild make
+	from scratch. This version of make tested with B20.1 of Cygwin.
+	Do not define BATCH_MODE_ONLY_SHELL if you use HAVE_CYGWIN_SHELL.
+
+GNU make and the MKS shell:
+
+	There is now semi-official support for the MKS shell. To turn this
+	support on, define HAVE_MKS_SHELL in the config.h.W32 before you
+	build make.  Do not define BATCH_MODE_ONLY_SHELL if you turn
+	on HAVE_MKS_SHELL.
+
+GNU make handling of drive letters in pathnames (PATH, vpath, VPATH):
+
+	There is a caveat that should be noted with respect to handling
+	single character pathnames on Windows systems.	When colon is
+	used in PATH variables, make tries to be smart about knowing when
+	you are using colon as a separator versus colon as a drive
+	letter.	 Unfortunately, something as simple as the string 'x:/'
+	could be interpreted 2 ways: (x and /) or (x:/).
+
+	Make chooses to interpret a letter plus colon (e.g. x:/) as a
+	drive letter pathname.	If it is necessary to use single
+	character directories in paths (VPATH, vpath, Path, PATH), the
+	user must do one of two things:
+
+	 a. Use semicolon as the separator to disambiguate colon. For
+	    example use 'x;/' if you want to say 'x' and '/' are
+	    separate components.
+
+	 b. Qualify the directory name so that there is more than
+	    one character in the path(s) used. For example, none
+	    of these settings are ambiguous:
+
+	      ./x:./y
+	      /some/path/x:/some/path/y
+	      x:/some/path/x:x:/some/path/y
+
+	Please note that you are free to mix colon and semi-colon in the
+	specification of paths.	 Make is able to figure out the intended
+	result and convert the paths internally to the format needed
+	when interacting with the operating system.
+
+	You are encouraged to use colon as the separator character.
+	This should ease the pain of deciding how to handle various path
+	problems which exist between platforms.	 If colon is used on
+	both Unix and Windows systems, then no ifdef'ing will be
+	necessary in the makefile source.
+
+GNU make test suite:
+
+	I verified all functionality with a slightly modified version
+	of make-test-%VERSION% (modifications to get test suite to run
+	on Windows NT). All tests pass in an environment that includes
+	sh.exe.  Tests were performed on both Windows NT and Windows 95.
+
+Building GNU make on Windows NT and Windows 95/98 with Microsoft Visual C:
+
+	I did not provide a Visual C project file with this port as
+	the project file would not be considered freely distributable
+	(or so I think). It is easy enough to create one, though, if
+	you know how to use Visual C.
+
+	I build the program statically to avoid problems locating DLL's
+	on machines that may not have MSVC runtime installed. If you
+	prefer, you can change make to build with shared libraries by
+	changing /MT to /MD in the NMakefile (or in build_w32.bat).
+
+	The program has not been built for non-Intel architectures (yet).
+
+	I have not tried to build with any other compilers than MSVC. I
+	have heard that this is possible though so don't be afraid to
+	notify me of your successes!
+
+Pathnames and white space:
+
+	Unlike Unix, Windows 95/NT systems encourage pathnames which
+	contain white space (e.g. C:\Program Files\). These sorts of pathnames
+	are legal under Unix too, but are never encouraged. There is
+	at least one place in make (VPATH/vpath handling) where paths
+	containing white space will simply not work. There may be others
+	too. I chose to not try and port make in such a way so that
+	these sorts of paths could be handled. I offer these suggestions
+	as workarounds:
+
+		1. Use 8.3 notation
+		2. Rename the directory so it does not contain white space.
+
+	If you are unhappy with this choice, this is free software
+	and you are free to take a crack at making this work. The code
+	in w32/pathstuff.c and vpath.c would be the places to start.
+
+Pathnames and Case insensitivity:
+
+	Unlike Unix, Windows 95/NT systems are case insensitive but case
+	preserving.  For example if you tell the file system to create a
+	file named "Target", it will preserve the case.  Subsequent access to
+	the file with other case permutations will succeed (i.e. opening a
+	file named "target" or "TARGET" will open the file "Target").
+
+	By default, GNU make retains its case sensitivity when comparing
+	target names and existing files or directories.  It can be
+	configured, however, into a case preserving and case insensitive
+	mode by adding a define for HAVE_CASE_INSENSITIVE_FS to
+	config.h.W32.
+
+	For example, the following makefile will create a file named
+	Target in the directory subdir which will subsequently be used
+	to satisfy the dependency of SUBDIR/DepTarget on SubDir/TARGET.
+	Without HAVE_CASE_INSENSITIVE_FS configured, the dependency link
+	will not be made:
+
+	subdir/Target:
+		touch $@
+
+	SUBDIR/DepTarget: SubDir/TARGET
+		cp $^ $@
+
+	Reliance on this behavior also eliminates the ability of GNU make
+	to use case in comparison of matching rules.  For example, it is
+	not possible to set up a C++ rule using %.C that is different
+	than a C rule using %.c.  GNU make will consider these to be the
+	same rule and will issue a warning.
+
+SAMBA/NTFS/VFAT:
+
+	I have not had any success building the debug version of this
+	package using SAMBA as my file server. The reason seems to be
+	related to the way VC++ 4.0 changes the case name of the pdb
+	filename it is passed on the command line. It seems to change
+	the name always to to lower case. I contend that
+	the VC++ compiler should not change the casename of files that
+	are passed as arguments on the command line. I don't think this
+	was a problem in MSVC 2.x, but I know it is a problem in MSVC 4.x.
+
+	The package builds fine on VFAT and NTFS filesystems.
+
+	Most all of the development I have done to date has been using
+	NTFS and long file names. I have not done any considerable work
+	under VFAT. VFAT users may wish to be aware that this port
+	of make does respect case sensitivity.
+
+FAT:
+
+	Version 3.76 added support for FAT filesystems. Make
+	works around some difficulties with stat'ing of
+	files and caching of filenames and directories internally.
+
+Bug reports:
+
+	Please submit bugs via the normal bug reporting mechanism which
+	is described in the GNU make manual and the base README.

+
+GNU make can utilize the Customs library, distributed with Pmake, to
+provide builds distributed across multiple hosts.
+
+In order to utilize this capability, you must first download and build
+the Customs library.  It is contained in the Pmake distribution, which
+can be obtained at:
+
+  ftp://ftp.icsi.berkeley.edu/pub/ai/stolcke/software/
+
+This integration was tested (superficially) with Pmake 2.1.33.
+
+
+BUILDING CUSTOMS
+----------------
+
+First, build pmake and Customs.  You need to build pmake first, because
+Customs require pmake to build.  Unfortunately, this is not trivial;
+please see the pmake and Customs documentation for details.  The best
+place to look for instructions is in the pmake-2.1.33/INSTALL file.
+
+Note that the 2.1.33 Pmake distribution comes with a set of patches to
+GNU make, distributed in the pmake-2.1.33/etc/gnumake/ directory.  These
+patches are based on GNU make 3.75 (there are patches for earlier
+versions of GNU make, also).  The parts of this patchfile which relate
+directly to Customs support have already been incorporated into this
+version of GNU make, so you should _NOT_ apply the patch file.
+
+However, there are a few non-Customs specific (as far as I could tell)
+changes here which are not incorporated (for example, the modification
+to try expanding -lfoo to libfoo.so).  If you rely on these changes
+you'll need to re-apply them by hand.
+
+Install the Customs library and header files according to the
+documentation.  You should also install the man pages (contrary to
+comments in the documentation, they weren't installed automatically for
+me; I had to cd to the ``pmake-2.1.33/doc'' directory and run ``pmake
+install'' there directly).
+
+
+BUILDING GNU MAKE
+-----------------
+
+Once you've installed Customs, you can build GNU make to use it.  When
+configuring GNU make, merely use the ``--with-customs=DIR'' option.
+Provide the directory containing the ``lib'' and ``include/customs''
+subdirectories as DIR.  For example, if you installed the customs
+library in /usr/local/lib and the headers in /usr/local/include/customs,
+then you'd pass ``--with-customs=/usr/local'' as an option to configure.
+
+Run make (or use build.sh) normally to build GNU make as described in
+the INSTALL file.
+
+See the documentation for Customs for information on starting and
+configuring Customs.
+
+
+INVOKING CUSTOMS-IZED GNU MAKE
+-----------------------------
+
+One thing you should be aware of is that the default build environment
+for Customs requires root permissions.  Practically, this means that GNU
+make must be installed setuid root to use Customs.
+
+If you don't want to do this, you can build Customs such that root
+permissions are not necessary.  Andreas Stolcke <stolcke@speech.sri.com>
+writes:
+
+ > pmake, gnumake or any other customs client program is not required to
+ > be suid root if customs was compiled WITHOUT the USE_RESERVED_PORTS
+ > option in customs/config.h.  Make sure the "customs" service in
+ > /etc/services is defined accordingly (port 8231 instead of 1001).
+
+ > Not using USE_RESERVED_PORTS means that a user with programming
+ > skills could impersonate another user by writing a fake customs
+ > client that pretends to be someone other than himself.  See the
+ > discussion in etc/SECURITY.
+
+
+PROBLEMS
+--------
+
+SunOS 4.1.x:
+  The customs/sprite.h header file #includes the <malloc.h> header
+  files; this conflicts with GNU make's configuration so you'll get a
+  compile error if you use GCC (or any other ANSI-capable C compiler).
+
+  I commented out the #include in sprite.h:107:
+
+    #if defined(sun) || defined(ultrix) || defined(hpux) || defined(sgi)
+    /* #include <malloc.h> */
+    #else
+
+  YMMV.

+
+Obtaining CVS Code
+------------------
+
+This seems redundant, since if you're reading this you most likely have
+already performed this step; however, for completeness, you can obtain
+the GNU make source code via anonymous CVS from the FSF's Savannah
+project <http://savannah.gnu.org/projects/make/>:
+
+  $ cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/make co make
+
+You might want to use the "-z3" option to get compression, and you most
+certainly will want the -P option to avoid unneeded directories
+cluttering up your source.  Personally I add these (as well as -dP for
+update) to my ~/.cvsrc file.
+
+
+If you have an older version of CVS, you might have to login first.
+There is no password; just hit the ENTER key if you are asked for one.
+
+
+Building From CVS
+-----------------
+
+To build GNU make from CVS, you will need Autoconf 2.57 (or better),
+Automake 1.7.3 (or better), and Gettext 0.11.5 (or better), and any
+tools that those utilities require (GNU m4, Perl, etc.).  You will also
+need a copy of wget.
+
+After checking out the code, you will need to perform these steps to get
+to the point where you can run "make".
+
+
+ 1) $ autoreconf -i -s
+
+    This rebuilds all the things that need rebuilding, installing
+    missing files as symbolic links.
+
+    You may get warnings here about missing files like README, etc.
+    Ignore them, they are harmless.
+
+
+ 2) $ ./configure
+
+    Generate a Makefile
+
+
+ 3) $ make update
+
+    Use wget to retrieve various other files that GNU make relies on,
+    but does not keep in its own source tree.
+
+    NB: You may need GNU make to correctly perform this step; if you use
+    a platform-local make you may get problems with missing files in doc/.
+
+
+At this point you have successfully brought your CVS copy of the GNU
+make source directory up to the point where it can be treated
+more-or-less like the official package you would get from ftp.gnu.org.
+That is, you can just run:
+
+  $ make && make check && make install
+
+to build and install GNU make.
+
+
+Creating a Package
+------------------
+
+Once you have performed the above steps (including the configuration and
+build) you can create a GNU make package.  This is very simple, just
+run:
+
+  $ make dist-gzip
+
+and, if you like:
+
+  $ make dist-bzip2
+
+Even better, you should run this:
+
+  $ make distcheck
+
+Which will build both .gz and .bz2 package files, then unpack them into
+a temporary location, try to build them, and repack them, verifying that
+everything works, you get the same results, _and_ no extraneous files
+are left over after the "distclean" rule--whew!!  Now, _that_ is why
+converting to Automake is worth the trouble!  A big "huzzah!" to Tom
+T. and the AutoToolers!
+
+
+That's it, you're done!
+
+
+Appendix A - For The Brave
+--------------------------
+
+For those of you who trust me implicitly, or are just brave (or
+foolhardy), here is a canned sequence of commands to build a GNU make
+distribution package from a virgin CVS source checkout (assuming all the
+prerequisites are available of course).
+
+This list is eminently suitable for a quick swipe o' the mouse and a
+swift click o' mouse-2 into an xterm.  Go for it!
+
+
+autoreconf -i -s
+./configure
+make update
+make
+make check
+make distcheck

+This directory contains the %VERSION% release of GNU Make.
+
+See the file NEWS for the user-visible changes from previous releases.
+In addition, there have been bugs fixed.
+
+Please check the system-specific notes below for any caveats related to
+your operating system.
+
+For general building and installation instructions, see the file INSTALL.
+
+If you need to build GNU Make and have no other `make' program to use,
+you can use the shell script `build.sh' instead.  To do this, first run
+`configure' as described in INSTALL.  Then, instead of typing `make' to
+build the program, type `sh build.sh'.  This should compile the program
+in the current directory.  Then you will have a Make program that you can
+use for `./make install', or whatever else.
+
+Some systems' Make programs are broken and cannot process the Makefile for
+GNU Make.  If you get errors from your system's Make when building GNU
+Make, try using `build.sh' instead.
+
+
+GNU Make is free software.  See the file COPYING for copying conditions.
+
+
+Downloading
+-----------
+
+GNU Make can be obtained in many different ways.  See a description here:
+
+  http://www.gnu.org/software/software.html
+
+
+Documentation
+-------------
+
+GNU make is fully documented in the GNU Make manual, which is contained
+in this distribution as the file make.texinfo.  You can also find
+on-line and preformatted (PostScript and DVI) versions at the FSF's web
+site.  There is information there about ordering hardcopy documentation.

+
+
+CVS Access
+----------
+
+The GNU make source repository is available via anonymous CVS from the
+GNU Subversions CVS server; look here for details:
+
+  http://savannah.gnu.org/cvs/?group_id=71
+
+Please note: you won't be able to build GNU make from CVS without
+installing appropriate maintainer's tools, such as GNU m4, automake,
+autoconf, Perl, GNU make, and GCC.  See the README.cvs file for hints on
+how to build GNU make once these tools are available.  We make no
+guarantees about the contents or quality of the latest code in the CVS
+repository: it is not unheard of for code that is known to be broken to
+be checked in.  Use at your own risk.
+
+
+System-specific Notes
+---------------------
+
+It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such
+that if you compile make with `cc -O' on AIX 3.2, it will not work correctly.
+It is said that using `cc' without `-O' does work.
+
+One area that is often a problem in configuration and porting is the code
+to check the system's current load average.  To make it easier to test and
+debug this code, you can do `make check-loadavg' to see if it works
+properly on your system.  (You must run `configure' beforehand, but you
+need not build Make itself to run this test.)
+
+Another potential source of porting problems is the support for large
+files (LFS) in configure for those operating systems that provide it.
+Please report any bugs that you find in this area.  If you run into
+difficulties, then as a workaround you should be able to disable LFS by
+adding the `--disable-largefile' option to the `configure' script.
+
+On systems that support micro- and nano-second timestamp values and
+where stat(2) provides this information, GNU make will use it when
+comparing timestamps to get the most accurate possible result.  However,
+note that many current implementations of tools that *set* timestamps do
+not preserve micro- or nano-second granularity.  This means that "cp -p"
+and other similar tools (tar, etc.) may not exactly duplicate timestamps
+with micro- and nano-second granularity on some systems.  If your build
+system contains rules that depend on proper behavior of tools like "cp
+-p", you should consider using the .LOW_RESOLUTION_TIME pseudo-target to
+force make to treat them properly.  See the manual for details.
+
+
+Ports
+-----
+
+  - See README.customs for details on integrating GNU make with the
+    Customs distributed build environment from the Pmake distribution.
+
+  - See readme.vms for details about GNU Make on OpenVMS.
+
+  - See README.Amiga for details about GNU Make on AmigaDOS.
+
+  - See README.W32 for details about GNU Make on Windows NT, 95, or 98.
+
+  - See README.DOS for compilation instructions on MS-DOS and MS-Windows
+    using DJGPP tools.
+
+    A precompiled binary of the MSDOS port of GNU Make is available as part
+    of DJGPP; see the WWW page http://www.delorie.com/djgpp/ for more
+    information.
+
+Please note there are two _separate_ ports of GNU make for Microsoft
+systems: a native Windows tool built with (for example) MSVC or Cygwin,
+and a DOS-based tool built with DJGPP.  Please be sure you are looking
+at the right README!

+GNU Make TODO List
+------------------
+
+This list comes both from the authors and from users of GNU make.
+
+They are listed in no particular order!
+
+Also, I don't gaurantee that all of them will be ultimately deemed "good
+ideas" and implemented.  These are just the ones that, at first blush,
+seem to have some merit (and that I can remember).
+
+However, if you see something here you really, really want, speak up.
+All other things being equal, I will tend to implement things that seem
+to maximize user satisfaction.
+
+If you want to implement some of them yourself, barring the ones I've
+marked below, have at it!  Please contact me first to let me know you're
+working on it, and give me some info about the design--and, critically,
+information about any user-visible syntax change, etc.
+
+
+The Top Item
+------------
+
+If you know perl (or want to learn DejaGNU or similar), the number one
+priority on my list of things I don't have time to do right now is
+fixing up the GNU make test suite.  Most importantly it needs to be made
+"parallelizable", so more than one regression can run at the same time
+(essentially, make the "work" directory local).  Also, the CWD during
+the test should be in the work directory or, better, a test-specific
+temporary directory so each test gets a new directory; right now
+sometimes tests leak files into the main directory which causes
+subsequent tests to fail (some tests may need to be tweaked).  Beyond
+that, any cleanup done to make writing, reading, or handling tests
+simpler would be great!  Please feel free to make whatever changes you
+like to the current tests, given some high-level goals, and that you'll
+port the current tests to whatever you do :).
+
+
+The Rest of the List
+--------------------
+
+ 1) Allow variables/functions to expand to other make rules which are
+    then interpreted, with newlines handled correctly.  This is a
+    biggee, and is on my plate.  I already have partially-working code.
+
+ 2) Option to check more than timestamps to determine if targets have
+    changed.  This is also a very big one.  It's _close_ to my plate :),
+    and I have very definite ideas about how I would like it done.
+    Please pick something else unless you must have this feature.  If
+    you try it, please work _extremely_ closely with me on it.
+
+ 2a) Possibly a special case of this is the .KEEP_STATE feature of Sun's
+     make.  Some great folks at W U. in Canada did an implementation of
+     this for a class project.  Their approach is reasonable and
+     workable, but doesn't really fit into my ideas for #2.  Maybe
+     that's OK.  I have paperwork for their work so if you want to do
+     this one talk to me to get what they've already done.
+
+     [K R Praveen <praveen@cair.res.in>]
+
+ 3) Currently you can use "%.foo %.bar : %.baz" to mean that one
+    invocation of the rule builds both targets.  GNU make needs a way to
+    do that for explicit rules, too.  I heard a rumor that some versions
+    of make all you to say "a.foo + a.bar : a.baz" to do this (i.e., a
+    "+" means one invocation builds both).  Don't know if this is the
+    best syntax or not... what if you say "a.foo + a.bar a.bam : a.baz";
+    what does that mean?
+
+ 4) Multi-token pattern rule matching (allow %1/%2.c : %1/obj/%2.o,
+    etc., or something like that).  I have an implementation of this
+    already, it just needs some refinement... maybe.  Additionally I
+    think it only works for static pattern rules; it might need to be
+    fixed up to work with normal pattern rules, too.
+
+ 5) More robust clock skew detection algorithm: less false hits.  I have
+    some notes on this from various discussions.
+
+ 6) Provide MAKETARGETS and MAKEVARIABLES variables, containing the
+    names of the targets and variables defined in the makefile.
+
+    Actually, I now think a $(targets ...) function, at least, would be
+    better than a MAKETARGETS variable.  The argument would be types of
+    targets to list: "phony" is the most useful one.  I suppose
+    "default" might also be useful.  Maybe some others; check the
+    bitfields to see what might be handy.  This one is pretty easy.
+
+ 7) Some sort of operating-system independent way of handling paths
+    would be outstanding, so makefiles can be written for UNIX, VMS,
+    DOS, MS-Windows, Amiga, etc. with a minimum of specialization.
+
+    Or, perhaps related/instead of, some sort of meta-quoting syntax so
+    make can deal with filenames containing spaces, colons, etc.  I
+    dunno, maybe something like $[...]?  This may well not be worth
+    doing until #1 is done.
+
+ 9) Right now the .PRECIOUS, .INTERMEDIATE, and .SECONDARY
+    pseudo-targets have different capabilities.  For example, .PRECIOUS
+    can take a "%", the others can't.  Etc.  These should all work the
+    same, insofar as that makes sense.
+
+10) A syntax that specifies a build order _without_ implying a
+    dependency relationship.  That is, a way to say "A must be built
+    before B" that doesn't force B to be built when A changes.  This is
+    very important for parallel builds: sometimes you need some stuff
+    done first but you don't want to rebuild everything because of it.
+
+11) Improved debugging/logging/etc. capabilities.  Part of this is done:
+    I introduced a number of debugging enhancements.  Tim Magill is (I
+    think) looking into options to control output more selectively.
+    One thing I want to do in debugging is add a flag to allow debugging
+    of variables as they're expanded (!).  This would be incredibly
+    verbose, but could be invaluable when nothing else seems to work and
+    you just can't figure it out.  The way variables are expanded now
+    means this isn't 100% trivial, but it probably won't be hard.
+
+12) Integration of Guile as an embedded scripting language.  This means:
+    allowing Guile functions to be declared in makefiles somehow, then
+    providing a syntax for invoking them.  At least one formulation of
+    that would have the function resolve to a string which would be
+    substituted in the makefile, kind of like $(shell ...) does now, but
+    using the embedded interpreter so there's no process forked of
+    course.  Obviously this is an optional add-on feature.
+
+    It could be more advanced than that, even, who knows?  Maybe make
+    could provide Guile functions that allow Guile scripts more direct
+    access to internal make structures, somehow.  This kind of thing
+    needs a lot of thought.
+
+    Also there's always the flip side: in some very fundamental ways
+    make isn't the best choice right now for a complex build tool.  It's
+    great for simple-to-medium tasks, but there are already other tools
+    available for the really tough situations.  Ask yourself,
+    realistically, how much work is worthwhile to add to make, given the
+    fundamentals you can't really overcome without significantly
+    affecting backward compatibility--and then why not use another tool
+    in the first place?
+
+    Something to think about.

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

+* Overview::                    Overview of @code{make}.
+* Introduction::                An introduction to @code{make}.
+* Makefiles::                   Makefiles tell @code{make} what to do.
+* Rules::                       Rules describe when a file must be remade.
+* Commands::                    Commands say how to remake a file.
+* Using Variables::             You can use variables to avoid repetition.
+* Conditionals::                Use or ignore parts of the makefile based
+                                  on the values of variables.
+* Functions::                   Many powerful ways to manipulate text.
+* Invoking make: Running.       How to invoke @code{make} on the command line.
+* Implicit Rules::              Use implicit rules to treat many files alike,
+                                  based on their file names.
+* Archives::                    How @code{make} can update library archives.
+* Features::                    Features GNU @code{make} has over other @code{make}s.
+* Missing::                     What GNU @code{make} lacks from other @code{make}s.
+* Makefile Conventions::        Conventions for writing makefiles for

+@chapter Overview of @code{make}
+
+The @code{make} utility automatically determines which pieces of a large
+program need to be recompiled, and issues commands to recompile them.
+This manual describes GNU @code{make}, which was implemented by Richard
+Stallman and Roland McGrath.  Development since Version 3.76 has been
+handled by Paul Smith.
+
+GNU @code{make} conforms to section 6.2 of @cite{IEEE Standard
+1003.2-1992} (POSIX.2).
+@cindex POSIX
+@cindex IEEE Standard 1003.2
+@cindex standards conformance
+
+Our examples show C programs, since they are most common, but you can use
+@code{make} with any programming language whose compiler can be run with a
+shell command.  Indeed, @code{make} is not limited to programs.  You can
+use it to describe any task where some files must be updated automatically
+from others whenever the others change.

+@heading Preparing and Running Make
+@end ifnottex
+
+To prepare to use @code{make}, you must write a file called
+the @dfn{makefile} that describes the relationships among files
+in your program and provides commands for updating each file.
+In a program, typically, the executable file is updated from object
+files, which are in turn made by compiling source files.@refill
+
+Once a suitable makefile exists, each time you change some source files,
+this simple shell command:
+
+@example
+make
+@end example
+
+@noindent
+suffices to perform all necessary recompilations.  The @code{make} program
+uses the makefile data base and the last-modification times of the files to
+decide which of the files need to be updated.  For each of those files, it
+issues the commands recorded in the data base.
+
+You can provide command line arguments to @code{make} to control which
+files should be recompiled, or how.  @xref{Running, ,How to Run
+@code{make}}.

+
+If you have problems with GNU @code{make} or think you've found a bug,
+please report it to the developers; we cannot promise to do anything but
+we might well want to fix it.
+
+Before reporting a bug, make sure you've actually found a real bug.
+Carefully reread the documentation and see if it really says you can do
+what you're trying to do.  If it's not clear whether you should be able
+to do something or not, report that too; it's a bug in the
+documentation!
+
+Before reporting a bug or trying to fix it yourself, try to isolate it
+to the smallest possible makefile that reproduces the problem.  Then
+send us the makefile and the exact results @code{make} gave you,
+including any error or warning messages.  Please don't paraphrase
+these messages: it's best to cut and paste them into your report.
+When generating this small makefile, be sure to not use any non-free
+or unusual tools in your commands: you can almost always emulate what
+such a tool would do with simple shell commands.  Finally, be sure to
+explain what you expected to occur; this will help us decide whether
+the problem was really in the documentation.
+
+Once you have a precise problem you can report it in one of two ways.
+Either send electronic mail to:
+
+@example
+    bug-make@@gnu.org
+@end example
+
+@noindent
+or use our Web-based project management tool, at:
+
+@example
+    http://savannah.gnu.org/projects/make/
+@end example
+
+@noindent
+In addition to the information above, please be careful to include the
+version number of @code{make} you are using.  You can get this
+information with the command @samp{make --version}.  Be sure also to
+include the type of machine and operating system you are using.  One
+way to obtain this information is by looking at the final lines of
+output from the command @samp{make --help}.

+@chapter An Introduction to Makefiles
+
+You need a file called a @dfn{makefile} to tell @code{make} what to do.
+Most often, the makefile tells @code{make} how to compile and link a
+program.
+@cindex makefile
+
+In this chapter, we will discuss a simple makefile that describes how to
+compile and link a text editor which consists of eight C source files
+and three header files.  The makefile can also tell @code{make} how to
+run miscellaneous commands when explicitly asked (for example, to remove
+certain files as a clean-up operation).  To see a more complex example
+of a makefile, see @ref{Complex Makefile}.
+
+When @code{make} recompiles the editor, each changed C source file
+must be recompiled.  If a header file has changed, each C source file
+that includes the header file must be recompiled to be safe.  Each
+compilation produces an object file corresponding to the source file.
+Finally, if any source file has been recompiled, all the object files,
+whether newly made or saved from previous compilations, must be linked
+together to produce the new executable editor.

+@section What a Rule Looks Like
+@cindex rule, introduction to
+@cindex makefile rule parts
+@cindex parts of makefile rule
+
+A simple makefile consists of ``rules'' with the following shape:
+
+@cindex targets, introduction to
+@cindex prerequisites, introduction to
+@cindex commands, introduction to
+@example
+@group
+@var{target} @dots{} : @var{prerequisites} @dots{}
+        @var{command}
+        @dots{}
+        @dots{}
+@end group
+@end example
+
+A @dfn{target} is usually the name of a file that is generated by a
+program; examples of targets are executable or object files.  A target
+can also be the name of an action to carry out, such as @samp{clean}
+(@pxref{Phony Targets}).
+
+A @dfn{prerequisite} is a file that is used as input to create the
+target.  A target often depends on several files.
+
+@cindex tabs in rules
+A @dfn{command} is an action that @code{make} carries out.
+A rule may have more than one command, each on its own line.
+@strong{Please note:} you need to put a tab character at the beginning of
+every command line!  This is an obscurity that catches the unwary.
+
+Usually a command is in a rule with prerequisites and serves to create a
+target file if any of the prerequisites change.  However, the rule that
+specifies commands for the target need not have prerequisites.  For
+example, the rule containing the delete command associated with the
+target @samp{clean} does not have prerequisites.
+
+A @dfn{rule}, then, explains how and when to remake certain files
+which are the targets of the particular rule.  @code{make} carries out
+the commands on the prerequisites to create or update the target.  A
+rule can also explain how and when to carry out an action.
+@xref{Rules, , Writing Rules}.
+
+A makefile may contain other text besides rules, but a simple makefile
+need only contain rules.  Rules may look somewhat more complicated
+than shown in this template, but all fit the pattern more or less.

+@section A Simple Makefile
+@cindex simple makefile
+@cindex makefile, simple
+
+Here is a straightforward makefile that describes the way an
+executable file called @code{edit} depends on eight object files
+which, in turn, depend on eight C source and three header files.
+
+In this example, all the C files include @file{defs.h}, but only those
+defining editing commands include @file{command.h}, and only low
+level files that change the editor buffer include @file{buffer.h}.
+
+@example
+@group
+edit : main.o kbd.o command.o display.o \
+       insert.o search.o files.o utils.o
+        cc -o edit main.o kbd.o command.o display.o \
+                   insert.o search.o files.o utils.o
+
+main.o : main.c defs.h
+        cc -c main.c
+kbd.o : kbd.c defs.h command.h
+        cc -c kbd.c
+command.o : command.c defs.h command.h
+        cc -c command.c
+display.o : display.c defs.h buffer.h
+        cc -c display.c
+insert.o : insert.c defs.h buffer.h
+        cc -c insert.c
+search.o : search.c defs.h buffer.h
+        cc -c search.c
+files.o : files.c defs.h buffer.h command.h
+        cc -c files.c
+utils.o : utils.c defs.h
+        cc -c utils.c
+clean :
+        rm edit main.o kbd.o command.o display.o \
+           insert.o search.o files.o utils.o

+To use this makefile to create the executable file called @file{edit},
+type:
+
+@example
+make
+@end example
+
+To use this makefile to delete the executable file and all the object
+files from the directory, type:
+
+@example
+make clean
+@end example
+
+In the example makefile, the targets include the executable file
+@samp{edit}, and the object files @samp{main.o} and @samp{kbd.o}.  The
+prerequisites are files such as @samp{main.c} and @samp{defs.h}.
+In fact, each @samp{.o} file is both a target and a prerequisite.
+Commands include @w{@samp{cc -c main.c}} and @w{@samp{cc -c kbd.c}}.
+
+When a target is a file, it needs to be recompiled or relinked if any
+of its prerequisites change.  In addition, any prerequisites that are
+themselves automatically generated should be updated first.  In this
+example, @file{edit} depends on each of the eight object files; the
+object file @file{main.o} depends on the source file @file{main.c} and
+on the header file @file{defs.h}.
+
+A shell command follows each line that contains a target and
+prerequisites.  These shell commands say how to update the target file.
+A tab character must come at the beginning of every command line to

+@section How @code{make} Processes a Makefile
+@cindex processing a makefile
+@cindex makefile, how @code{make} processes
+
+By default, @code{make} starts with the first target (not targets whose
+names start with @samp{.}).  This is called the @dfn{default goal}.
+(@dfn{Goals} are the targets that @code{make} strives ultimately to
+update.  @xref{Goals, , Arguments to Specify the Goals}.)
+@cindex default goal
+@cindex goal, default
+@cindex goal
+
+In the simple example of the previous section, the default goal is to
+update the executable program @file{edit}; therefore, we put that rule
+first.
+
+Thus, when you give the command:
+
+@example
+make
+@end example
+
+@noindent
+@code{make} reads the makefile in the current directory and begins by
+processing the first rule.  In the example, this rule is for relinking
+@file{edit}; but before @code{make} can fully process this rule, it
+must process the rules for the files that @file{edit} depends on,
+which in this case are the object files.  Each of these files is
+processed according to its own rule.  These rules say to update each
+@samp{.o} file by compiling its source file.  The recompilation must
+be done if the source file, or any of the header files named as
+prerequisites, is more recent than the object file, or if the object
+file does not exist.
+
+The other rules are processed because their targets appear as
+prerequisites of the goal.  If some other rule is not depended on by the
+goal (or anything it depends on, etc.), that rule is not processed,
+unless you tell @code{make} to do so (with a command such as
+@w{@code{make clean}}).
+
+Before recompiling an object file, @code{make} considers updating its
+prerequisites, the source file and header files.  This makefile does not
+specify anything to be done for them---the @samp{.c} and @samp{.h} files
+are not the targets of any rules---so @code{make} does nothing for these
+files.  But @code{make} would update automatically generated C programs,
+such as those made by Bison or Yacc, by their own rules at this time.
+
+After recompiling whichever object files need it, @code{make} decides
+whether to relink @file{edit}.  This must be done if the file
+@file{edit} does not exist, or if any of the object files are newer than
+it.  If an object file was just recompiled, it is now newer than
+@file{edit}, so @file{edit} is relinked.
+@cindex relinking
+
+Thus, if we change the file @file{insert.c} and run @code{make},
+@code{make} will compile that file to update @file{insert.o}, and then
+link @file{edit}.  If we change the file @file{command.h} and run
+@code{make}, @code{make} will recompile the object files @file{kbd.o},
+@file{command.o} and @file{files.o} and then link the file @file{edit}.
+
+@node Variables Simplify, make Deduces, How Make Works, Introduction
+@section Variables Make Makefiles Simpler
+@cindex variables
+@cindex simplifying with variables
+
+In our example, we had to list all the object files twice in the rule for
+@file{edit} (repeated here):
+
+@example
+@group
+edit : main.o kbd.o command.o display.o \
+              insert.o search.o files.o utils.o
+        cc -o edit main.o kbd.o command.o display.o \
+                   insert.o search.o files.o utils.o
+@end group
+@end example
+
+@cindex @code{objects}
+Such duplication is error-prone; if a new object file is added to the
+system, we might add it to one list and forget the other.  We can eliminate
+the risk and simplify the makefile by using a variable.  @dfn{Variables}
+allow a text string to be defined once and substituted in multiple places
+later (@pxref{Using Variables, ,How to Use Variables}).
+
+@cindex @code{OBJECTS}
+@cindex @code{objs}
+@cindex @code{OBJS}
+@cindex @code{obj}
+@cindex @code{OBJ}
+It is standard practice for every makefile to have a variable named
+@code{objects}, @code{OBJECTS}, @code{objs}, @code{OBJS}, @code{obj},
+or @code{OBJ} which is a list of all object file names.  We would
+define such a variable @code{objects} with a line like this in the
+makefile:@refill
+
+@example
+@group
+objects = main.o kbd.o command.o display.o \
+          insert.o search.o files.o utils.o
+@end group
+@end example
+
+@noindent
+Then, each place we want to put a list of the object file names, we can
+substitute the variable's value by writing @samp{$(objects)}
+(@pxref{Using Variables, ,How to Use Variables}).
+
+Here is how the complete simple makefile looks when you use a variable
+for the object files:
+
+@example
+@group
+objects = main.o kbd.o command.o display.o \
+          insert.o search.o files.o utils.o

+@cindex rule, implicit, introduction to
+
+It is not necessary to spell out the commands for compiling the individual
+C source files, because @code{make} can figure them out: it has an
+@dfn{implicit rule} for updating a @samp{.o} file from a correspondingly
+named @samp{.c} file using a @samp{cc -c} command.  For example, it will
+use the command @samp{cc -c main.c -o main.o} to compile @file{main.c} into
+@file{main.o}.  We can therefore omit the commands from the rules for the
+object files.  @xref{Implicit Rules, ,Using Implicit Rules}.@refill
+
+When a @samp{.c} file is used automatically in this way, it is also
+automatically added to the list of prerequisites.  We can therefore omit
+the @samp{.c} files from the prerequisites, provided we omit the commands.
+
+Here is the entire example, with both of these changes, and a variable
+@code{objects} as suggested above:
+
+@example
+@group
+objects = main.o kbd.o command.o display.o \
+          insert.o search.o files.o utils.o
+
+edit : $(objects)
+        cc -o edit $(objects)
+
+main.o : defs.h
+kbd.o : defs.h command.h

+utils.o : defs.h
+
+.PHONY : clean

+        rm edit $(objects)

+
+@noindent
+This is how we would write the makefile in actual practice.  (The
+complications associated with @samp{clean} are described elsewhere.
+See @ref{Phony Targets}, and @ref{Errors, ,Errors in Commands}.)
+
+Because implicit rules are so convenient, they are important.  You
+will see them used frequently.@refill
+
+@node Combine By Prerequisite, Cleanup, make Deduces, Introduction
+@section Another Style of Makefile
+@cindex combining rules by prerequisite
+
+When the objects of a makefile are created only by implicit rules, an
+alternative style of makefile is possible.  In this style of makefile,
+you group entries by their prerequisites instead of by their targets.
+Here is what one looks like:
+
+@example
+@group
+objects = main.o kbd.o command.o display.o \
+          insert.o search.o files.o utils.o
+
+edit : $(objects)
+        cc -o edit $(objects)
+
+$(objects) : defs.h
+kbd.o command.o files.o : command.h
+display.o insert.o search.o files.o : buffer.h
+@end group
+@end example
+
+@noindent
+Here @file{defs.h} is given as a prerequisite of all the object files;
+@file{command.h} and @file{buffer.h} are prerequisites of the specific
+object files listed for them.
+
+Whether this is better is a matter of taste: it is more compact, but some
+people dislike it because they find it clearer to put all the information
+about each target in one place.
+
+@node Cleanup,  , Combine By Prerequisite, Introduction
+@section Rules for Cleaning the Directory
+@cindex cleaning up
+@cindex removing, to clean up
+
+Compiling a program is not the only thing you might want to write rules
+for.  Makefiles commonly tell how to do a few other things besides
+compiling a program: for example, how to delete all the object files
+and executables so that the directory is @samp{clean}.
+
+@cindex @code{clean} target
+Here is how we
+could write a @code{make} rule for cleaning our example editor:
+
+@example
+@group
+clean:
+        rm edit $(objects)
+@end group
+@end example
+
+In practice, we might want to write the rule in a somewhat more
+complicated manner to handle unanticipated situations.  We would do this:
+
+@example
+@group
+.PHONY : clean
+clean :
+        -rm edit $(objects)
+@end group
+@end example
+
+@noindent
+This prevents @code{make} from getting confused by an actual file
+called @file{clean} and causes it to continue in spite of errors from
+@code{rm}.  (See @ref{Phony Targets}, and @ref{Errors, ,Errors in
+Commands}.)
+
+@noindent
+A rule such as this should not be placed at the beginning of the
+makefile, because we do not want it to run by default!  Thus, in the
+example makefile, we want the rule for @code{edit}, which recompiles
+the editor, to remain the default goal.
+
+Since @code{clean} is not a prerequisite of @code{edit}, this rule will not
+run at all if we give the command @samp{make} with no arguments.  In
+order to make the rule run, we have to type @samp{make clean}.

+length in later chapters.@refill
+
+@itemize @bullet
+@cindex rule, explicit, definition of
+@cindex explicit rule, definition of
+@item
+An @dfn{explicit rule} says when and how to remake one or more files,
+called the rule's @dfn{targets}.  It lists the other files that the
+targets depend on, called the @dfn{prerequisites} of the target, and
+may also give commands to use to create or update the targets.
+@xref{Rules, ,Writing Rules}.
+
+@cindex rule, implicit, definition of
+@cindex implicit rule, definition of
+@item
+An @dfn{implicit rule} says when and how to remake a class of files
+based on their names.  It describes how a target may depend on a file
+with a name similar to the target and gives commands to create or
+update such a target.  @xref{Implicit Rules, ,Using Implicit Rules}.
+
+@cindex variable definition
+@item
+A @dfn{variable definition} is a line that specifies a text string
+value for a variable that can be substituted into the text later.  The
+simple makefile example shows a variable definition for @code{objects}
+as a list of all object files (@pxref{Variables Simplify, , Variables
+Make Makefiles Simpler}).
+
+@cindex directive
+@item
+A @dfn{directive} is a command for @code{make} to do something special while
+reading the makefile.  These include:
+
+@itemize @bullet
+@item
+Reading another makefile (@pxref{Include, ,Including Other Makefiles}).
+
+@item
+Deciding (based on the values of variables) whether to use or
+ignore a part of the makefile (@pxref{Conditionals, ,Conditional Parts of Makefiles}).
+
+@item
+Defining a variable from a verbatim string containing multiple lines
+(@pxref{Defining, ,Defining Variables Verbatim}).
+@end itemize
+
+@cindex comments, in makefile
+@cindex @code{#} (comments), in makefile
+@item
+@samp{#} in a line of a makefile starts a @dfn{comment}.  It and the
+rest of the line are ignored, except that a trailing backslash not
+escaped by another backslash will continue the comment across multiple
+lines.  A line containing just a comment (with perhaps spaces before
+it) is effectively blank, and is ignored.  If you want a literal
+@code{#}, escape it with a backslash (e.g., @code{\#}).  Comments may
+appear on any line in the makefile, although they are treated
+specially in certain situations.
+
+Within a command script (if the line begins with a TAB character) the
+entire line is passed to the shell, just as with any other line that
+begins with a TAB.  The shell decides how to interpret the text:
+whether or not this is a comment is up to the shell.
+
+Within a @code{define} directive, comments are not ignored during the
+definition of the variable, but rather kept intact in the value of the
+variable.  When the variable is expanded they will either be treated
+as @code{make} comments or as command script text, depending on the
+context in which the variable is evaluated.

+Normally you should call your makefile either @file{makefile} or

+prominently near the beginning of a directory listing, right near other
+important files such as @file{README}.)  The first name checked,
+@file{GNUmakefile}, is not recommended for most makefiles.  You should
+use this name if you have a makefile that is specific to GNU
+@code{make}, and will not be understood by other versions of
+@code{make}.  Other @code{make} programs look for @file{makefile} and
+@file{Makefile}, but not @file{GNUmakefile}.
+
+If @code{make} finds none of these names, it does not use any makefile.
+Then you must specify a goal with a command argument, and @code{make}
+will attempt to figure out how to remake it using only its built-in
+implicit rules.  @xref{Implicit Rules, ,Using Implicit Rules}.
+
+@cindex @code{-f}

+@cindex @code{--makefile}
+If you want to use a nonstandard name for your makefile, you can specify

+@code{make} to read the file @var{name} as the makefile.  If you use
+more than one @samp{-f} or @samp{--file} option, you can specify several
+makefiles.  All the makefiles are effectively concatenated in the order

+The @code{include} directive tells @code{make} to suspend reading the
+current makefile and read one or more other makefiles before continuing.
+The directive is a line in the makefile that looks like this:
+
+@example
+include @var{filenames}@dots{}
+@end example
+
+@noindent
+@var{filenames} can contain shell file name patterns.
+@cindex shell file name pattern (in @code{include})

+@cindex wildcard, in @code{include}
+
+Extra spaces are allowed and ignored at the beginning of the line, but
+a tab is not allowed.  (If the line begins with a tab, it will be
+considered a command line.)  Whitespace is required between
+@code{include} and the file names, and between file names; extra
+whitespace is ignored there and at the end of the directive.  A
+comment starting with @samp{#} is allowed at the end of the line.  If
+the file names contain any variable or function references, they are
+expanded.  @xref{Using Variables, ,How to Use Variables}.
+
+For example, if you have three @file{.mk} files, @file{a.mk},
+@file{b.mk}, and @file{c.mk}, and @code{$(bar)} expands to
+@code{bish bash}, then the following expression
+
+@example
+include foo *.mk $(bar)
+@end example
+
+is equivalent to
+
+@example
+include foo a.mk b.mk c.mk bish bash
+@end example
+
+When @code{make} processes an @code{include} directive, it suspends
+reading of the containing makefile and reads from each listed file in
+turn.  When that is finished, @code{make} resumes reading the
+makefile in which the directive appears.
+
+One occasion for using @code{include} directives is when several programs,
+handled by individual makefiles in various directories, need to use a
+common set of variable definitions
+(@pxref{Setting, ,Setting Variables}) or pattern rules
+(@pxref{Pattern Rules, ,Defining and Redefining Pattern Rules}).
+
+Another such occasion is when you want to generate prerequisites from
+source files automatically; the prerequisites can be put in a file that
+is included by the main makefile.  This practice is generally cleaner
+than that of somehow appending the prerequisites to the end of the main
+makefile as has been traditionally done with other versions of

+If the specified name does not start with a slash, and the file is not
+found in the current directory, several other directories are searched.
+First, any directories you have specified with the @samp{-I} or
+@samp{--include-dir} option are searched
+(@pxref{Options Summary, ,Summary of Options}).
+Then the following directories (if they exist)
+are searched, in this order:

+@footnote{GNU Make compiled for MS-DOS and MS-Windows behaves as if
+@var{prefix} has been defined to be the root of the DJGPP tree
+hierarchy.})
+@file{/usr/gnu/include},
+@file{/usr/local/include}, @file{/usr/include}.
+
+If an included makefile cannot be found in any of these directories, a
+warning message is generated, but it is not an immediately fatal error;
+processing of the makefile containing the @code{include} continues.
+Once it has finished reading makefiles, @code{make} will try to remake
+any that are out of date or don't exist.
+@xref{Remaking Makefiles, ,How Makefiles Are Remade}.
+Only after it has tried to find a way to remake a makefile and failed,
+will @code{make} diagnose the missing makefile as a fatal error.
+
+If you want @code{make} to simply ignore a makefile which does not exist
+and cannot be remade, with no error message, use the @w{@code{-include}}
+directive instead of @code{include}, like this:
+
+@example
+-include @var{filenames}@dots{}
+@end example
+
+This acts like @code{include} in every way except that there is no
+error (not even a warning) if any of the @var{filenames} do not exist.
+For compatibility with some other @code{make} implementations,

+GNU @code{make} also supports a special variable.  Note that any value
+you assign to this variable will be ignored; it will always return its
+special value.
+
+@vindex $(.VARIABLES)
+@vindex .VARIABLES @r{(list of variables)}
+The first special variable is @code{.VARIABLES}.  When expanded, the
+value consists of a list of the @emph{names} of all global variables
+defined in all makefiles read up until that point.  This includes
+variables which have empty values, as well as built-in variables
+(@pxref{Implicit Variables, , Variables Used by Implicit Rules}), but
+does not include any variables which are only defined in a
+target-specific context.
+
+@c @vindex $(.TARGETS)
+@c @vindex .TARGETS @r{(list of targets)}
+@c The second special variable is @code{.TARGETS}.  When expanded, the
+@c value consists of a list of all targets defined in all makefiles read
+@c up until that point.  Note it's not enough for a file to be simply
+@c mentioned in the makefile to be listed in this variable, even if it
+@c would match an implicit rule and become an ``implicit target''.  The
+@c file must appear as a target, on the left-hand side of a ``:'', to be
+@c considered a target for the purposes of this variable.

+@section How Makefiles Are Remade
+
+@cindex updating makefiles
+@cindex remaking makefiles
+@cindex makefile, remaking of
+Sometimes makefiles can be remade from other files, such as RCS or SCCS
+files.  If a makefile can be remade from other files, you probably want
+@code{make} to get an up-to-date version of the makefile to read in.
+
+To this end, after reading in all makefiles, @code{make} will consider
+each as a goal target and attempt to update it.  If a makefile has a
+rule which says how to update it (found either in that very makefile or
+in another one) or if an implicit rule applies to it (@pxref{Implicit
+Rules, ,Using Implicit Rules}), it will be updated if necessary.  After
+all makefiles have been checked, if any have actually been changed,
+@code{make} starts with a clean slate and reads all the makefiles over
+again.  (It will also attempt to update each of them over again, but
+normally this will not change them again, since they are already up to
+date.)@refill
+
+If you know that one or more of your makefiles cannot be remade and you
+want to keep @code{make} from performing an implicit rule search on
+them, perhaps for efficiency reasons, you can use any normal method of
+preventing implicit rule lookup to do so.  For example, you can write an
+explicit rule with the makefile as the target, and an empty command
+string (@pxref{Empty Commands, ,Using Empty Commands}).
+
+If the makefiles specify a double-colon rule to remake a file with
+commands but no prerequisites, that file will always be remade
+(@pxref{Double-Colon}).  In the case of makefiles, a makefile that has a
+double-colon rule with commands but no prerequisites will be remade every
+time @code{make} is run, and then again after @code{make} starts over
+and reads the makefiles in again.  This would cause an infinite loop:
+@code{make} would constantly remake the makefile, and never do anything
+else.  So, to avoid this, @code{make} will @strong{not} attempt to
+remake makefiles which are specified as targets of a double-colon rule
+with commands but no prerequisites.@refill
+
+If you do not specify any makefiles to be read with @samp{-f} or
+@samp{--file} options, @code{make} will try the default makefile names;
+@pxref{Makefile Names, ,What Name to Give Your Makefile}.  Unlike
+makefiles explicitly requested with @samp{-f} or @samp{--file} options,
+@code{make} is not certain that these makefiles should exist.  However,
+if a default makefile does not exist but can be created by running
+@code{make} rules, you probably want the rules to be run so that the
+makefile can be used.
+
+Therefore, if none of the default makefiles exists, @code{make} will try
+to make each of them in the same order in which they are searched for
+(@pxref{Makefile Names, ,What Name to Give Your Makefile})
+until it succeeds in making one, or it runs out of names to try.  Note
+that it is not an error if @code{make} cannot find or make any makefile;
+a makefile is not always necessary.@refill
+
+When you use the @samp{-t} or @samp{--touch} option
+(@pxref{Instead of Execution, ,Instead of Executing the Commands}),
+you would not want to use an out-of-date makefile to decide which
+targets to touch.  So the @samp{-t} option has no effect on updating
+makefiles; they are really updated even if @samp{-t} is specified.
+Likewise, @samp{-q} (or @samp{--question}) and @samp{-n} (or
+@samp{--just-print}) do not prevent updating of makefiles, because an
+out-of-date makefile would result in the wrong output for other targets.
+Thus, @samp{make -f mfile -n foo} will update @file{mfile}, read it in,
+and then print the commands to update @file{foo} and its prerequisites
+without running them.  The commands printed for @file{foo} will be those
+specified in the updated contents of @file{mfile}.
+
+However, on occasion you might actually wish to prevent updating of even
+the makefiles.  You can do this by specifying the makefiles as goals in
+the command line as well as specifying them as makefiles.  When the
+makefile name is specified explicitly as a goal, the options @samp{-t}
+and so on do apply to them.
+
+Thus, @samp{make -f mfile -n mfile foo} would read the makefile
+@file{mfile}, print the commands needed to update it without actually
+running them, and then print the commands needed to update @file{foo}
+without running them.  The commands for @file{foo} will be those
+specified by the existing contents of @file{mfile}.
+
+@node Overriding Makefiles, Reading Makefiles, Remaking Makefiles, Makefiles
+@section Overriding Part of Another Makefile
+
+@cindex overriding makefiles
+@cindex makefile, overriding
+Sometimes it is useful to have a makefile that is mostly just like
+another makefile.  You can often use the @samp{include} directive to
+include one in the other, and add more targets or variable definitions.
+However, if the two makefiles give different commands for the same
+target, @code{make} will not let you just do this.  But there is another way.
+
+@cindex match-anything rule, used to override
+In the containing makefile (the one that wants to include the other),
+you can use a match-anything pattern rule to say that to remake any
+target that cannot be made from the information in the containing
+makefile, @code{make} should look in another makefile.
+@xref{Pattern Rules}, for more information on pattern rules.
+
+For example, if you have a makefile called @file{Makefile} that says how
+to make the target @samp{foo} (and other targets), you can write a
+makefile called @file{GNUmakefile} that contains:
+
+@example
+foo:
+        frobnicate > foo
+
+%: force
+        @@$(MAKE) -f Makefile $@@
+force: ;
+@end example
+
+If you say @samp{make foo}, @code{make} will find @file{GNUmakefile},
+read it, and see that to make @file{foo}, it needs to run the command
+@samp{frobnicate > foo}.  If you say @samp{make bar}, @code{make} will
+find no way to make @file{bar} in @file{GNUmakefile}, so it will use the
+commands from the pattern rule: @samp{make -f Makefile bar}.  If
+@file{Makefile} provides a rule for updating @file{bar}, @code{make}
+will apply the rule.  And likewise for any other target that
+@file{GNUmakefile} does not say how to make.
+
+The way this works is that the pattern rule has a pattern of just
+@samp{%}, so it matches any target whatever.  The rule specifies a
+prerequisite @file{force}, to guarantee that the commands will be run even
+if the target file already exists.  We give @file{force} target empty
+commands to prevent @code{make} from searching for an implicit rule to
+build it---otherwise it would apply the same match-anything rule to
+@file{force} itself and create a prerequisite loop!

+@node Reading Makefiles,  , Overriding Makefiles, Makefiles
+@section How @code{make} Reads a Makefile
+@cindex reading makefiles
+@cindex makefile, parsing
+
+GNU @code{make} does its work in two distinct phases.  During the first
+phase it reads all the makefiles, included makefiles, etc. and
+internalizes all the variables and their values, implicit and explicit
+rules, and constructs a dependency graph of all the targets and their
+prerequisites.  During the second phase, @code{make} uses these internal
+structures to determine what targets will need to be rebuilt and to
+invoke the rules necessary to do so.
+
+It's important to understand this two-phase approach because it has a
+direct impact on how variable and function expansion happens; this is
+often a source of some confusion when writing makefiles.  Here we will
+present a summary of the phases in which expansion happens for different
+constructs within the makefile.  We say that expansion is
+@dfn{immediate} if it happens during the first phase: in this case
+@code{make} will expand any variables or functions in that section of a
+construct as the makefile is parsed.  We say that expansion is
+@dfn{deferred} if expansion is not performed immediately.  Expansion of
+deferred construct is not performed until either the construct appears
+later in an immediate context, or until the second phase.
+
+You may not be familiar with some of these constructs yet.  You can
+reference this section as you become familiar with them, in later
+chapters.
+
+@subheading Variable Assignment
+@cindex +=, expansion
+@cindex =, expansion
+@cindex ?=, expansion
+@cindex +=, expansion
+@cindex define, expansion
+
+Variable definitions are parsed as follows:
+
+@example
+@var{immediate} = @var{deferred}
+@var{immediate} ?= @var{deferred}
+@var{immediate} := @var{immediate}
+@var{immediate} += @var{deferred} or @var{immediate}
+
+define @var{immediate}
+  @var{deferred}
+endef
+@end example
+
+For the append operator, @samp{+=}, the right-hand side is considered
+immediate if the variable was previously set as a simple variable
+(@samp{:=}), and deferred otherwise.
+
+@subheading Conditional Statements
+@cindex ifdef, expansion
+@cindex ifeq, expansion
+@cindex ifndef, expansion
+@cindex ifneq, expansion
+
+All instances of conditional syntax are parsed immediately, in their
+entirety; this includes the @code{ifdef}, @code{ifeq}, @code{ifndef},
+and @code{ifneq} forms.
+
+@subheading Rule Definition
+@cindex target, expansion
+@cindex prerequisite, expansion
+@cindex implicit rule, expansion
+@cindex pattern rule, expansion
+@cindex explicit rule, expansion
+
+A rule is always expanded the same way, regardless of the form:
+
+@example
+@var{immediate} : @var{immediate} ; @var{deferred}
+	@var{deferred}
+@end example
+
+That is, the target and prerequisite sections are expanded immediately,
+and the commands used to construct the target are always deferred.  This
+general rule is true for explicit rules, pattern rules, suffix rules,
+static pattern rules, and simple prerequisite definitions.

+@cindex writing rules
+@cindex rule, how to write
+@cindex target
+@cindex prerequisite
+
+A @dfn{rule} appears in the makefile and says when and how to remake
+certain files, called the rule's @dfn{targets} (most often only one per rule).
+It lists the other files that are the @dfn{prerequisites} of the target, and
+@dfn{commands} to use to create or update the target.
+
+@cindex default goal
+@cindex goal, default
+The order of rules is not significant, except for determining the
+@dfn{default goal}: the target for @code{make} to consider, if you do
+not otherwise specify one.  The default goal is the target of the first
+rule in the first makefile.  If the first rule has multiple targets,
+only the first target is taken as the default.  There are two
+exceptions: a target starting with a period is not a default unless it
+contains one or more slashes, @samp{/}, as well; and, a target that
+defines a pattern rule has no effect on the default goal.
+(@xref{Pattern Rules, ,Defining and Redefining Pattern Rules}.)
+
+Therefore, we usually write the makefile so that the first rule is the
+one for compiling the entire program or all the programs described by
+the makefile (often with a target called @samp{all}).

+@cindex normal prerequisites
+@cindex prerequisites, order-only
+@cindex order-only prerequisites
+There are actually two different types of prerequisites understood by
+GNU @code{make}: normal prerequisites such as described in the
+previous section, and @dfn{order-only} prerequisites.  A normal
+prerequisite makes two statements: first, it imposes an order of
+execution of build commands: any commands necessary to build any of a
+target's prerequisites will be fully executed before any commands
+necessary to build the target.  Second, it imposes a dependency
+relationship: if any prerequisite is newer than the target, then the
+target is considered out-of-date and must be rebuilt.
+
+Normally, this is exactly what you want: if a target's prerequisite is
+updated, then the target should also be updated.
+
+Occasionally, however, you have a situation where you want to impose a
+specific ordering on the rules to be invoked @emph{without} forcing
+the target to be updated if one of those rules is executed.  In that
+case, you want to define @dfn{order-only} prerequisites.  Order-only
+prerequisites can be specified by placing a pipe symbol (@code{|})
+in the prerequisites list: any prerequisites to the left of the pipe
+symbol are normal; any prerequisites to the right are order-only:
+
+@example
+@var{targets} : @var{normal-prerequisites} | @var{order-only-prerequisites}
+@end example
+
+The normal prerequisites section may of course be empty.  Also, you
+may still declare multiple lines of prerequisites for the same target:
+they are appended appropriately.  Note that if you declare the same
+file to be both a normal and an order-only prerequisite, the normal
+prerequisite takes precedence (since they are a strict superset of the
+behavior of an order-only prerequisite).

+@cindex @code{*} (wildcard character)

+A single file name can specify many files using @dfn{wildcard characters}.
+The wildcard characters in @code{make} are @samp{*}, @samp{?} and
+@samp{[@dots{}]}, the same as in the Bourne shell.  For example, @file{*.c}
+specifies a list of all the files (in the working directory) whose names
+end in @samp{.c}.@refill
+
+@cindex @code{~} (tilde)
+@cindex tilde (@code{~})
+@cindex home directory
+The character @samp{~} at the beginning of a file name also has special
+significance.  If alone, or followed by a slash, it represents your home
+directory.  For example @file{~/bin} expands to @file{/home/you/bin}.
+If the @samp{~} is followed by a word, the string represents the home
+directory of the user named by that word.  For example @file{~john/bin}
+expands to @file{/home/john/bin}.  On systems which don't have a home
+directory for each user (such as MS-DOS or MS-Windows), this
+functionality can be simulated by setting the environment variable
+@var{HOME}.@refill
+
+Wildcard expansion happens automatically in targets, in prerequisites,
+and in commands (where the shell does the expansion).  In other
+contexts, wildcard expansion happens only if you request it explicitly
+with the @code{wildcard} function.
+
+The special significance of a wildcard character can be turned off by
+preceding it with a backslash.  Thus, @file{foo\*bar} would refer to a
+specific file whose name consists of @samp{foo}, an asterisk, and

+@subsection Wildcard Examples
+
+Wildcards can be used in the commands of a rule, where they are expanded
+by the shell.  For example, here is a rule to delete all the object files:
+
+@example
+@group
+clean:
+        rm -f *.o
+@end group
+@end example
+@cindex @code{rm} (shell command)
+
+Wildcards are also useful in the prerequisites of a rule.  With the
+following rule in the makefile, @samp{make print} will print all the
+@samp{.c} files that have changed since the last time you printed them:
+
+@example
+print: *.c
+        lpr -p $?
+        touch print
+@end example
+
+@cindex @code{print} target
+@cindex @code{lpr} (shell command)
+@cindex @code{touch} (shell command)
+@noindent
+This rule uses @file{print} as an empty target file; see @ref{Empty
+Targets, ,Empty Target Files to Record Events}.  (The automatic variable
+@samp{$?} is used to print only those files that have changed; see
+@ref{Automatic Variables}.)@refill
+
+Wildcard expansion does not happen when you define a variable.  Thus, if
+you write this:
+
+@example
+objects = *.o
+@end example
+
+@noindent
+then the value of the variable @code{objects} is the actual string
+@samp{*.o}.  However, if you use the value of @code{objects} in a target,
+prerequisite or command, wildcard expansion will take place at that time.
+To set @code{objects} to the expansion, instead use:
+
+@example
+objects := $(wildcard *.o)
+@end example

+@cindex mistakes with wildcards
+@cindex errors with wildcards
+@cindex problems with wildcards
+
+Now here is an example of a naive way of using wildcard expansion, that
+does not do what you would intend.  Suppose you would like to say that the
+executable file @file{foo} is made from all the object files in the
+directory, and you write this:
+
+@example
+objects = *.o
+
+foo : $(objects)
+        cc -o foo $(CFLAGS) $(objects)
+@end example
+
+@noindent
+The value of @code{objects} is the actual string @samp{*.o}.  Wildcard
+expansion happens in the rule for @file{foo}, so that each @emph{existing}
+@samp{.o} file becomes a prerequisite of @file{foo} and will be recompiled if
+necessary.
+
+But what if you delete all the @samp{.o} files?  When a wildcard matches
+no files, it is left as it is, so then @file{foo} will depend on the
+oddly-named file @file{*.o}.  Since no such file is likely to exist,
+@code{make} will give you an error saying it cannot figure out how to
+make @file{*.o}.  This is not what you want!
+
+Actually it is possible to obtain the desired result with wildcard
+expansion, but you need more sophisticated techniques, including the
+@code{wildcard} function and string substitution.

+@cindex wildcards and MS-DOS/MS-Windows backslashes

+Microsoft operating systems (MS-DOS and MS-Windows) use backslashes to

+
+@example
+  c:\foo\bar\baz.c
+@end example
+
+This is equivalent to the Unix-style @file{c:/foo/bar/baz.c} (the
+@file{c:} part is the so-called drive letter).  When @code{make} runs on

+
+@node Wildcard Function,  , Wildcard Pitfall, Wildcards
+@subsection The Function @code{wildcard}
+@findex wildcard
+
+Wildcard expansion happens automatically in rules.  But wildcard expansion
+does not normally take place when a variable is set, or inside the
+arguments of a function.  If you want to do wildcard expansion in such
+places, you need to use the @code{wildcard} function, like this:
+
+@example
+$(wildcard @var{pattern}@dots{})
+@end example
+
+@noindent
+This string, used anywhere in a makefile, is replaced by a
+space-separated list of names of existing files that match one of the
+given file name patterns.  If no existing file name matches a pattern,
+then that pattern is omitted from the output of the @code{wildcard}
+function.  Note that this is different from how unmatched wildcards
+behave in rules, where they are used verbatim rather than ignored
+(@pxref{Wildcard Pitfall}).
+
+One use of the @code{wildcard} function is to get a list of all the C source
+files in a directory, like this:
+
+@example
+$(wildcard *.c)
+@end example
+
+We can change the list of C source files into a list of object files by
+replacing the @samp{.c} suffix with @samp{.o} in the result, like this:
+
+@example
+$(patsubst %.c,%.o,$(wildcard *.c))
+@end example
+
+@noindent
+(Here we have used another function, @code{patsubst}.
+@xref{Text Functions, ,Functions for String Substitution and Analysis}.)@refill
+
+Thus, a makefile to compile all C source files in the directory and then
+link them together could be written as follows:
+
+@example
+objects := $(patsubst %.c,%.o,$(wildcard *.c))
+
+foo : $(objects)
+        cc -o foo $(objects)
+@end example
+
+@noindent
+(This takes advantage of the implicit rule for compiling C programs, so
+there is no need to write explicit rules for compiling the files.

+@subsection @code{VPATH}: Search Path for All Prerequisites
+@vindex VPATH
+
+The value of the @code{make} variable @code{VPATH} specifies a list of
+directories that @code{make} should search.  Most often, the
+directories are expected to contain prerequisite files that are not in the
+current directory; however, @code{VPATH} specifies a search list that
+@code{make} applies for all files, including files which are targets of
+rules.
+
+Thus, if a file that is listed as a target or prerequisite does not exist
+in the current directory, @code{make} searches the directories listed in
+@code{VPATH} for a file with that name.  If a file is found in one of
+them, that file may become the prerequisite (see below).  Rules may then
+specify the names of files in the prerequisite list as if they all
+existed in the current directory.  @xref{Commands/Search, ,Writing Shell
+Commands with Directory Search}.
+
+In the @code{VPATH} variable, directory names are separated by colons or
+blanks.  The order in which directories are listed is the order followed
+by @code{make} in its search.  (On MS-DOS and MS-Windows, semi-colons
+are used as separators of directory names in @code{VPATH}, since the
+colon can be used in the pathname itself, after the drive letter.)
+
+For example,
+
+@example
+VPATH = src:../headers
+@end example
+
+@noindent
+specifies a path containing two directories, @file{src} and
+@file{../headers}, which @code{make} searches in that order.
+
+With this value of @code{VPATH}, the following rule,
+
+@example
+foo.o : foo.c
+@end example
+
+@noindent
+is interpreted as if it were written like this:
+
+@example
+foo.o : src/foo.c
+@end example

+@noindent
+assuming the file @file{foo.c} does not exist in the current directory but
+is found in the directory @file{src}.
+
+@node Selective Search, Search Algorithm, General Search, Directory Search
+@subsection The @code{vpath} Directive
+@findex vpath
+
+Similar to the @code{VPATH} variable, but more selective, is the
+@code{vpath} directive (note lower case), which allows you to specify a
+search path for a particular class of file names: those that match a
+particular pattern.  Thus you can supply certain search directories for
+one class of file names and other directories (or none) for other file
+names.
+
+There are three forms of the @code{vpath} directive:
+
+@table @code
+@item vpath @var{pattern} @var{directories}
+Specify the search path @var{directories} for file names that match
+@var{pattern}.
+
+The search path, @var{directories}, is a list of directories to be
+searched, separated by colons (semi-colons on MS-DOS and MS-Windows) or
+blanks, just like the search path used in the @code{VPATH} variable.
+
+@item vpath @var{pattern}
+Clear out the search path associated with @var{pattern}.
+
+@c Extra blank line makes sure this gets two lines.
+@item vpath
+
+Clear all search paths previously specified with @code{vpath} directives.
+@end table
+
+A @code{vpath} pattern is a string containing a @samp{%} character.  The
+string must match the file name of a prerequisite that is being searched
+for, the @samp{%} character matching any sequence of zero or more
+characters (as in pattern rules; @pxref{Pattern Rules, ,Defining and
+Redefining Pattern Rules}).  For example, @code{%.h} matches files that
+end in @code{.h}.  (If there is no @samp{%}, the pattern must match the
+prerequisite exactly, which is not useful very often.)
+
+@cindex @code{%}, quoting in @code{vpath}
+@cindex @code{%}, quoting with @code{\} (backslash)
+@cindex @code{\} (backslash), to quote @code{%}
+@cindex backslash (@code{\}), to quote @code{%}
+@cindex quoting @code{%}, in @code{vpath}
+@samp{%} characters in a @code{vpath} directive's pattern can be quoted
+with preceding backslashes (@samp{\}).  Backslashes that would otherwise
+quote @samp{%} characters can be quoted with more backslashes.
+Backslashes that quote @samp{%} characters or other backslashes are
+removed from the pattern before it is compared to file names.  Backslashes
+that are not in danger of quoting @samp{%} characters go unmolested.@refill
+
+When a prerequisite fails to exist in the current directory, if the
+@var{pattern} in a @code{vpath} directive matches the name of the
+prerequisite file, then the @var{directories} in that directive are searched
+just like (and before) the directories in the @code{VPATH} variable.
+
+For example,
+
+@example
+vpath %.h ../headers
+@end example
+
+@noindent
+tells @code{make} to look for any prerequisite whose name ends in @file{.h}
+in the directory @file{../headers} if the file is not found in the current
+directory.
+
+If several @code{vpath} patterns match the prerequisite file's name, then
+@code{make} processes each matching @code{vpath} directive one by one,
+searching all the directories mentioned in each directive.  @code{make}
+handles multiple @code{vpath} directives in the order in which they
+appear in the makefile; multiple directives with the same pattern are
+independent of each other.
+
+@need 750
+Thus,
+
+@example
+@group
+vpath %.c foo
+vpath %   blish
+vpath %.c bar
+@end group
+@end example
+
+@noindent
+will look for a file ending in @samp{.c} in @file{foo}, then
+@file{blish}, then @file{bar}, while
+
+@example
+@group
+vpath %.c foo:bar
+vpath %   blish
+@end group
+@end example
+
+@noindent
+will look for a file ending in @samp{.c} in @file{foo}, then
+@file{bar}, then @file{blish}.

+@node Search Algorithm, Commands/Search, Selective Search, Directory Search
+@subsection How Directory Searches are Performed
+@cindex algorithm for directory search
+@cindex directory search algorithm
+
+When a prerequisite is found through directory search, regardless of type
+(general or selective), the pathname located may not be the one that
+@code{make} actually provides you in the prerequisite list.  Sometimes
+the path discovered through directory search is thrown away.
+
+The algorithm @code{make} uses to decide whether to keep or abandon a
+path found via directory search is as follows:
+
+@enumerate
+@item
+If a target file does not exist at the path specified in the makefile,
+directory search is performed.
+
+@item
+If the directory search is successful, that path is kept and this file
+is tentatively stored as the target.
+
+@item
+All prerequisites of this target are examined using this same method.
+
+@item
+After processing the prerequisites, the target may or may not need to be
+rebuilt:
+
+@enumerate a
+@item
+If the target does @emph{not} need to be rebuilt, the path to the file
+found during directory search is used for any prerequisite lists which
+contain this target.  In short, if @code{make} doesn't need to rebuild
+the target then you use the path found via directory search.
+
+@item
+If the target @emph{does} need to be rebuilt (is out-of-date), the
+pathname found during directory search is @emph{thrown away}, and the
+target is rebuilt using the file name specified in the makefile.  In
+short, if @code{make} must rebuild, then the target is rebuilt locally,
+not in the directory found via directory search.
+@end enumerate
+@end enumerate
+
+This algorithm may seem complex, but in practice it is quite often
+exactly what you want.
+
+@cindex traditional directory search (GPATH)
+@cindex directory search, traditional (GPATH)
+Other versions of @code{make} use a simpler algorithm: if the file does
+not exist, and it is found via directory search, then that pathname is
+always used whether or not the target needs to be built.  Thus, if the
+target is rebuilt it is created at the pathname discovered during
+directory search.
+
+@vindex GPATH
+If, in fact, this is the behavior you want for some or all of your
+directories, you can use the @code{GPATH} variable to indicate this to
+@code{make}.
+
+@code{GPATH} has the same syntax and format as @code{VPATH} (that is, a
+space- or colon-delimited list of pathnames).  If an out-of-date target
+is found by directory search in a directory that also appears in
+@code{GPATH}, then that pathname is not thrown away.  The target is
+rebuilt using the expanded path.

+@subsection Writing Shell Commands with Directory Search
+@cindex shell command, and directory search
+@cindex directory search (@code{VPATH}), and shell commands
+
+When a prerequisite is found in another directory through directory search,
+this cannot change the commands of the rule; they will execute as written.
+Therefore, you must write the commands with care so that they will look for
+the prerequisite in the directory where @code{make} finds it.
+
+This is done with the @dfn{automatic variables} such as @samp{$^}
+(@pxref{Automatic Variables}).
+For instance, the value of @samp{$^} is a
+list of all the prerequisites of the rule, including the names of
+the directories in which they were found, and the value of
+@samp{$@@} is the target.  Thus:@refill
+
+@example
+foo.o : foo.c
+        cc -c $(CFLAGS) $^ -o $@@

+(The variable @code{CFLAGS} exists so you can specify flags for C
+compilation by implicit rules; we use it here for consistency so it will
+affect all C compilations uniformly;
+@pxref{Implicit Variables, ,Variables Used by Implicit Rules}.)
+
+Often the prerequisites include header files as well, which you do not
+want to mention in the commands.  The automatic variable @samp{$<} is
+just the first prerequisite:
+
+@example
+VPATH = src:../headers
+foo.o : foo.c defs.h hack.h

+
+The search through the directories specified in @code{VPATH} or with

+(@pxref{Implicit Rules, ,Using Implicit Rules}).
+
+For example, when a file @file{foo.o} has no explicit rule, @code{make}
+considers implicit rules, such as the built-in rule to compile
+@file{foo.c} if that file exists.  If such a file is lacking in the
+current directory, the appropriate directories are searched for it.  If
+@file{foo.c} exists (or is mentioned in the makefile) in any of the
+directories, the implicit rule for C compilation is applied.
+
+The commands of implicit rules normally use automatic variables as a
+matter of necessity; consequently they will use the file names found by
+directory search with no extra effort.

+@cindex @code{-l} (library search)
+@cindex link libraries, patterns matching
+@cindex @code{.LIBPATTERNS}, and link libraries
+@vindex .LIBPATTERNS
+
+Directory search applies in a special way to libraries used with the
+linker.  This special feature comes into play when you write a prerequisite
+whose name is of the form @samp{-l@var{name}}.  (You can tell something
+strange is going on here because the prerequisite is normally the name of a
+file, and the @emph{file name} of a library generally looks like
+@file{lib@var{name}.a}, not like @samp{-l@var{name}}.)@refill
+
+When a prerequisite's name has the form @samp{-l@var{name}}, @code{make}
+handles it specially by searching for the file @file{lib@var{name}.so} in
+the current directory, in directories specified by matching @code{vpath}
+search paths and the @code{VPATH} search path, and then in the
+directories @file{/lib}, @file{/usr/lib}, and @file{@var{prefix}/lib}
+(normally @file{/usr/local/lib}, but MS-DOS/MS-Windows versions of
+@code{make} behave as if @var{prefix} is defined to be the root of the
+DJGPP installation tree).
+
+If that file is not found, then the file @file{lib@var{name}.a} is
+searched for, in the same directories as above.
+
+For example, if there is a @file{/usr/lib/libcurses.a} library on your
+system (and no @file{/usr/lib/libcurses.so} file), then
+
+@example
+@group
+foo : foo.c -lcurses
+        cc $^ -o $@@
+@end group
+@end example
+
+@noindent
+would cause the command @samp{cc foo.c /usr/lib/libcurses.a -o foo} to
+be executed when @file{foo} is older than @file{foo.c} or than
+@file{/usr/lib/libcurses.a}.@refill
+
+Although the default set of files to be searched for is
+@file{lib@var{name}.so} and @file{lib@var{name}.a}, this is customizable
+via the @code{.LIBPATTERNS} variable.  Each word in the value of this
+variable is a pattern string.  When a prerequisite like
+@samp{-l@var{name}} is seen, @code{make} will replace the percent in
+each pattern in the list with @var{name} and perform the above directory
+searches using that library filename.  If no library is found, the next
+word in the list will be used.
+
+The default value for @code{.LIBPATTERNS} is ``@samp{lib%.so lib%.a}'',
+which provides the default behavior described above.
+
+You can turn off link library expansion completely by setting this
+variable to an empty value.

+@node Phony Targets, Force Targets, Directory Search, Rules
+@section Phony Targets
+@cindex phony targets
+@cindex targets, phony
+@cindex targets without a file
+
+A phony target is one that is not really the name of a file.  It is just a
+name for some commands to be executed when you make an explicit request.
+There are two reasons to use a phony target: to avoid a conflict with
+a file of the same name, and to improve performance.
+
+If you write a rule whose commands will not create the target file, the
+commands will be executed every time the target comes up for remaking.
+Here is an example:
+
+@example
+@group
+clean:
+        rm *.o temp
+@end group
+@end example
+
+@noindent
+Because the @code{rm} command does not create a file named @file{clean},
+probably no such file will ever exist.  Therefore, the @code{rm} command
+will be executed every time you say @samp{make clean}.
+@cindex @code{rm} (shell command)
+
+@findex .PHONY
+The phony target will cease to work if anything ever does create a file
+named @file{clean} in this directory.  Since it has no prerequisites, the
+file @file{clean} would inevitably be considered up to date, and its
+commands would not be executed.  To avoid this problem, you can explicitly
+declare the target to be phony, using the special target @code{.PHONY}
+(@pxref{Special Targets, ,Special Built-in Target Names}) as follows:
+
+@example
+.PHONY : clean
+@end example
+
+@noindent
+Once this is done, @samp{make clean} will run the commands regardless of
+whether there is a file named @file{clean}.
+
+Since it knows that phony targets do not name actual files that could be
+remade from other files, @code{make} skips the implicit rule search for
+phony targets (@pxref{Implicit Rules}).  This is why declaring a target
+phony is good for performance, even if you are not worried about the
+actual file existing.
+
+Thus, you first write the line that states that @code{clean} is a
+phony target, then you write the rule, like this:
+
+@example
+@group
+.PHONY: clean
+clean:
+        rm *.o temp
+@end group
+@end example
+
+Another example of the usefulness of phony targets is in conjunction
+with recursive invocations of @code{make} (for more information, see
+@ref{Recursion, ,Recursive Use of @code{make}}).  In this case the
+makefile will often contain a variable which lists a number of
+subdirectories to be built.  One way to handle this is with one rule
+whose command is a shell loop over the subdirectories, like this:
+
+@example
+@group
+SUBDIRS = foo bar baz
+
+subdirs:
+        for dir in $(SUBDIRS); do \
+          $(MAKE) -C $$dir; \
+        done
+@end group
+@end example
+
+There are a few problems with this method, however.  First, any error
+detected in a submake is not noted by this rule, so it will continue to
+build the rest of the directories even when one fails.  This can be
+overcome by adding shell commands to note the error and exit, but then
+it will do so even if @code{make} is invoked with the @code{-k} option,
+which is unfortunate.  Second, and perhaps more importantly, you cannot
+take advantage of the parallel build capabilities of make using this
+method, since there is only one rule.
+
+By declaring the subdirectories as phony targets (you must do this as
+the subdirectory obviously always exists; otherwise it won't be built)
+you can remove these problems:
+
+@example
+@group
+SUBDIRS = foo bar baz
+
+.PHONY: subdirs $(SUBDIRS)
+
+subdirs: $(SUBDIRS)
+
+$(SUBDIRS):
+        $(MAKE) -C $@@
+
+foo: baz
+@end group
+@end example
+
+Here we've also declared that the @file{foo} subdirectory cannot be
+built until after the @file{baz} subdirectory is complete; this kind of
+relationship declaration is particularly important when attempting
+parallel builds.
+
+A phony target should not be a prerequisite of a real target file; if it
+is, its commands are run every time @code{make} goes to update that
+file.  As long as a phony target is never a prerequisite of a real
+target, the phony target commands will be executed only when the phony
+target is a specified goal (@pxref{Goals, ,Arguments to Specify the
+Goals}).
+
+Phony targets can have prerequisites.  When one directory contains multiple
+programs, it is most convenient to describe all of the programs in one
+makefile @file{./Makefile}.  Since the target remade by default will be the
+first one in the makefile, it is common to make this a phony target named
+@samp{all} and give it, as prerequisites, all the individual programs.  For
+example:
+
+@example
+all : prog1 prog2 prog3
+.PHONY : all
+
+prog1 : prog1.o utils.o
+        cc -o prog1 prog1.o utils.o
+
+prog2 : prog2.o
+        cc -o prog2 prog2.o
+
+prog3 : prog3.o sort.o utils.o
+        cc -o prog3 prog3.o sort.o utils.o
+@end example
+
+@noindent
+Now you can say just @samp{make} to remake all three programs, or specify
+as arguments the ones to remake (as in @samp{make prog1 prog3}).
+
+When one phony target is a prerequisite of another, it serves as a subroutine
+of the other.  For example, here @samp{make cleanall} will delete the
+object files, the difference files, and the file @file{program}:
+
+@example
+.PHONY: cleanall cleanobj cleandiff
+
+cleanall : cleanobj cleandiff
+        rm program
+
+cleanobj :
+        rm *.o
+
+cleandiff :
+        rm *.diff

+
+If a rule has no prerequisites or commands, and the target of the rule

+
+The @dfn{empty target} is a variant of the phony target; it is used to hold
+commands for an action that you request explicitly from time to time.
+Unlike a phony target, this target file can really exist; but the file's
+contents do not matter, and usually are empty.
+
+The purpose of the empty target file is to record, with its
+last-modification time, when the rule's commands were last executed.  It
+does so because one of the commands is a @code{touch} command to update the
+target file.
+
+The empty target file should have some prerequisites (otherwise it
+doesn't make sense).  When you ask to remake the empty target, the
+commands are executed if any prerequisite is more recent than the target;
+in other words, if a prerequisite has changed since the last time you
+remade the target.  Here is an example:
+
+@example
+print: foo.c bar.c

+@cindex @code{touch} (shell command)

+
+The high resolution file time stamps of many modern hosts lessen the
+chance of @command{make} incorrectly concluding that a file is up to
+date.  Unfortunately, these hosts provide no way to set a high
+resolution file time stamp, so commands like @samp{cp -p} that
+explicitly set a file's time stamp must discard its subsecond part.  If
+a file is created by such a command, you should list it as a
+prerequisite of @code{.LOW_RESOLUTION_TIME} so that @command{make} does
+not mistakenly conclude that the file is out of date.  For example:
+
+@example
+@group
+.LOW_RESOLUTION_TIME: dst
+dst: src
+        cp -p src dst
+@end group
+@end example
+
+Since @samp{cp -p} discards the subsecond part of @file{src}'s time
+stamp, @file{dst} is typically slightly older than @file{src} even when
+it is up to date.  The @code{.LOW_RESOLUTION_TIME} line causes
+@command{make} to consider @file{dst} to be up to date if its time stamp
+is at the start of the same second that @file{src}'s time stamp is in.
+
+Due to a limitation of the archive format, archive member time stamps

+
+A rule with multiple targets is equivalent to writing many rules, each with
+one target, and all identical aside from that.  The same commands apply to
+all the targets, but their effects may vary because you can substitute the
+actual target name into the command using @samp{$@@}.  The rule contributes
+the same prerequisites to all the targets also.
+
+This is useful in two cases.
+
+@itemize @bullet
+@item
+You want just prerequisites, no commands.  For example:
+
+@example

+@end example
+

+gives an additional prerequisite to each of the three object files
+mentioned.
+
+@item
+Similar commands work for all the targets.  The commands do not need
+to be absolutely identical, since the automatic variable @samp{$@@}
+can be used to substitute the particular target to be remade into the
+commands (@pxref{Automatic Variables}).  For example:
+
+@example
+@group
+bigoutput littleoutput : text.g
+        generate text.g -$(subst output,,$@@) > $@@
+@end group

+Suppose you would like to vary the prerequisites according to the target,

+
+One file can be the target of several rules.  All the prerequisites
+mentioned in all the rules are merged into one list of prerequisites for
+the target.  If the target is older than any prerequisite from any rule,
+the commands are executed.
+
+There can only be one set of commands to be executed for a file.  If
+more than one rule gives commands for the same file, @code{make} uses
+the last set given and prints an error message.  (As a special case,
+if the file's name begins with a dot, no error message is printed.
+This odd behavior is only for compatibility with other implementations
+of @code{make}... you should avoid using it).  Occasionally it is
+useful to have the same target invoke multiple commands which are
+defined in different parts of your makefile; you can use
+@dfn{double-colon rules} (@pxref{Double-Colon}) for this.
+
+An extra rule with just prerequisites can be used to give a few extra
+prerequisites to many files at once.  For example, makefiles often
+have a variable, such as @code{objects}, containing a list of all the
+compiler output files in the system being made.  An easy way to say
+that all of them must be recompiled if @file{config.h} changes is to
+write the following:
+
+@example
+objects = foo.o bar.o
+foo.o : defs.h
+bar.o : defs.h test.h
+$(objects) : config.h
+@end example
+
+This could be inserted or taken out without changing the rules that really
+specify how to make the object files, making it a convenient form to use if
+you wish to add the additional prerequisite intermittently.
+
+Another wrinkle is that the additional prerequisites could be specified with
+a variable that you set with a command argument to @code{make}
+(@pxref{Overriding, ,Overriding Variables}).  For example,
+
+@example
+@group
+extradeps=
+$(objects) : $(extradeps)
+@end group
+@end example
+
+@noindent
+means that the command @samp{make extradeps=foo.h} will consider
+@file{foo.h} as a prerequisite of each object file, but plain @samp{make}
+will not.
+
+If none of the explicit rules for a target has commands, then @code{make}

+        @var{commands}
+        @dots{}
+@end example
+
+@noindent
+The @var{targets} list specifies the targets that the rule applies to.
+The targets can contain wildcard characters, just like the targets of
+ordinary rules (@pxref{Wildcards, ,Using Wildcard Characters in File
+Names}).
+
+@cindex target pattern, static (not implicit)
+@cindex stem
+The @var{target-pattern} and @var{prereq-patterns} say how to compute the
+prerequisites of each target.  Each target is matched against the
+@var{target-pattern} to extract a part of the target name, called the
+@dfn{stem}.  This stem is substituted into each of the @var{prereq-patterns}
+to make the prerequisite names (one from each @var{prereq-pattern}).
+
+Each pattern normally contains the character @samp{%} just once.  When the
+@var{target-pattern} matches a target, the @samp{%} can match any part of
+the target name; this part is called the @dfn{stem}.  The rest of the
+pattern must match exactly.  For example, the target @file{foo.o} matches
+the pattern @samp{%.o}, with @samp{foo} as the stem.  The targets
+@file{foo.c} and @file{foo.out} do not match that pattern.@refill
+
+@cindex prerequisite pattern, static (not implicit)
+The prerequisite names for each target are made by substituting the stem
+for the @samp{%} in each prerequisite pattern.  For example, if one
+prerequisite pattern is @file{%.c}, then substitution of the stem
+@samp{foo} gives the prerequisite name @file{foo.c}.  It is legitimate
+to write a prerequisite pattern that does not contain @samp{%}; then this
+prerequisite is the same for all targets.

+@samp{%} characters in pattern rules can be quoted with preceding
+backslashes (@samp{\}).  Backslashes that would otherwise quote @samp{%}
+characters can be quoted with more backslashes.  Backslashes that quote
+@samp{%} characters or other backslashes are removed from the pattern
+before it is compared to file names or has a stem substituted into it.
+Backslashes that are not in danger of quoting @samp{%} characters go
+unmolested.  For example, the pattern @file{the\%weird\\%pattern\\} has
+@samp{the%weird\} preceding the operative @samp{%} character, and
+@samp{pattern\\} following it.  The final two backslashes are left alone
+because they cannot affect any @samp{%} character.@refill
+
+Here is an example, which compiles each of @file{foo.o} and @file{bar.o}
+from the corresponding @file{.c} file:
+
+@example
+@group
+objects = foo.o bar.o
+
+all: $(objects)

+$(objects): %.o: %.c
+        $(CC) -c $(CFLAGS) $< -o $@@
+@end group
+@end example
+
+@noindent
+Here @samp{$<} is the automatic variable that holds the name of the
+prerequisite and @samp{$@@} is the automatic variable that holds the name
+of the target; see @ref{Automatic Variables}.
+
+Each target specified must match the target pattern; a warning is issued
+for each target that does not.  If you have a list of files, only some of
+which will match the pattern, you can use the @code{filter} function to
+remove nonmatching file names (@pxref{Text Functions, ,Functions for String Substitution and Analysis}):
+
+@example
+files = foo.elc bar.o lose.o
+
+$(filter %.o,$(files)): %.o: %.c
+        $(CC) -c $(CFLAGS) $< -o $@@
+$(filter %.elc,$(files)): %.elc: %.el
+        emacs -f batch-byte-compile $<
+@end example
+
+@noindent
+In this example the result of @samp{$(filter %.o,$(files))} is
+@file{bar.o lose.o}, and the first static pattern rule causes each of
+these object files to be updated by compiling the corresponding C source
+file.  The result of @w{@samp{$(filter %.elc,$(files))}} is
+@file{foo.elc}, so that file is made from @file{foo.el}.@refill
+
+Another example shows how to use @code{$*} in static pattern rules:
+@vindex $*@r{, and static pattern}
+
+@example
+@group
+bigoutput littleoutput : %output : text.g
+        generate text.g -$* > $@@
+@end group

+When the @code{generate} command is run, @code{$*} will expand to the
+stem, either @samp{big} or @samp{little}.

+@node Static versus Implicit,  , Static Usage, Static Pattern
+@subsection Static Pattern Rules versus Implicit Rules
+@cindex rule, static pattern versus implicit
+@cindex static pattern rule, versus implicit
+
+A static pattern rule has much in common with an implicit rule defined as a
+pattern rule (@pxref{Pattern Rules, ,Defining and Redefining Pattern Rules}).
+Both have a pattern for the target and patterns for constructing the
+names of prerequisites.  The difference is in how @code{make} decides
+@emph{when} the rule applies.
+
+An implicit rule @emph{can} apply to any target that matches its pattern,
+but it @emph{does} apply only when the target has no commands otherwise
+specified, and only when the prerequisites can be found.  If more than one
+implicit rule appears applicable, only one applies; the choice depends on
+the order of rules.
+
+By contrast, a static pattern rule applies to the precise list of targets
+that you specify in the rule.  It cannot apply to any other target and it
+invariably does apply to each of the targets specified.  If two conflicting
+rules apply, and both have commands, that's an error.
+
+The static pattern rule can be better than an implicit rule for these
+reasons:
+
+@itemize @bullet
+@item
+You may wish to override the usual implicit rule for a few
+files whose names cannot be categorized syntactically but
+can be given in an explicit list.
+
+@item
+If you cannot be sure of the precise contents of the directories
+you are using, you may not be sure which other irrelevant files
+might lead @code{make} to use the wrong implicit rule.  The choice
+might depend on the order in which the implicit rule search is done.
+With static pattern rules, there is no uncertainty: each rule applies
+to precisely the targets specified.

+@cindex @code{::} rules (double-colon)
+
+@dfn{Double-colon} rules are rules written with @samp{::} instead of
+@samp{:} after the target names.  They are handled differently from
+ordinary rules when the same target appears in more than one rule.
+
+When a target appears in multiple rules, all the rules must be the same
+type: all ordinary, or all double-colon.  If they are double-colon, each
+of them is independent of the others.  Each double-colon rule's commands
+are executed if the target is older than any prerequisites of that rule.
+If there are no prerequisites for that rule, its commands are always
+executed (even if the target already exists).  This can result in
+executing none, any, or all of the double-colon rules.
+
+Double-colon rules with the same target are in fact completely separate
+from one another.  Each double-colon rule is processed individually, just
+as rules with different targets are processed.
+
+The double-colon rules for a target are executed in the order they appear
+in the makefile.  However, the cases where double-colon rules really make
+sense are those where the order of executing the commands would not matter.
+
+Double-colon rules are somewhat obscure and not often very useful; they
+provide a mechanism for cases in which the method used to update a target
+differs depending on which prerequisite files caused the update, and such
+cases are rare.
+
+Each double-colon rule should specify commands; if it does not, an
+implicit rule will be used if one applies.

+@cindex automatic generation of prerequisites
+@cindex generating prerequisites automatically
+
+In the makefile for a program, many of the rules you need to write often
+say only that some object file depends on some header
+file.  For example, if @file{main.c} uses @file{defs.h} via an
+@code{#include}, you would write:
+
+@example
+main.o: defs.h
+@end example
+
+@noindent
+You need this rule so that @code{make} knows that it must remake
+@file{main.o} whenever @file{defs.h} changes.  You can see that for a
+large program you would have to write dozens of such rules in your
+makefile.  And, you must always be very careful to update the makefile
+every time you add or remove an @code{#include}.
+@cindex @code{#include}
+
+@cindex @code{-M} (to compiler)
+To avoid this hassle, most modern C compilers can write these rules for
+you, by looking at the @code{#include} lines in the source files.
+Usually this is done with the @samp{-M} option to the compiler.
+For example, the command:
+
+@example
+cc -M main.c
+@end example
+
+@noindent
+generates the output:
+
+@example
+main.o : main.c defs.h
+@end example
+
+@noindent
+Thus you no longer have to write all those rules yourself.
+The compiler will do it for you.
+
+Note that such a prerequisite constitutes mentioning @file{main.o} in a
+makefile, so it can never be considered an intermediate file by implicit
+rule search.  This means that @code{make} won't ever remove the file
+after using it; @pxref{Chained Rules, ,Chains of Implicit Rules}.
+
+@cindex @code{make depend}
+With old @code{make} programs, it was traditional practice to use this
+compiler feature to generate prerequisites on demand with a command like
+@samp{make depend}.  That command would create a file @file{depend}
+containing all the automatically-generated prerequisites; then the
+makefile could use @code{include} to read them in (@pxref{Include}).
+
+In GNU @code{make}, the feature of remaking makefiles makes this
+practice obsolete---you need never tell @code{make} explicitly to
+regenerate the prerequisites, because it always regenerates any makefile
+that is out of date.  @xref{Remaking Makefiles}.
+
+The practice we recommend for automatic prerequisite generation is to have
+one makefile corresponding to each source file.  For each source file
+@file{@var{name}.c} there is a makefile @file{@var{name}.d} which lists
+what files the object file @file{@var{name}.o} depends on.  That way
+only the source files that have changed need to be rescanned to produce
+the new prerequisites.
+
+Here is the pattern rule to generate a file of prerequisites (i.e., a makefile)
+called @file{@var{name}.d} from a C source file called @file{@var{name}.c}:
+
+@smallexample
+@group
+%.d: %.c
+        @set -e; rm -f $@@; \
+         $(CC) -M $(CPPFLAGS) $< > $@@.$$$$; \

+         rm -f $@@.$$$$
+@end group
+@end smallexample
+
+@noindent
+@xref{Pattern Rules}, for information on defining pattern rules.  The
+@samp{-e} flag to the shell causes it to exit immediately if the
+@code{$(CC)} command (or any other command) fails (exits with a
+nonzero status).
+@cindex @code{-e} (shell flag)
+
+@cindex @code{-MM} (to GNU compiler)
+With the GNU C compiler, you may wish to use the @samp{-MM} flag instead
+of @samp{-M}.  This omits prerequisites on system header files.
+@xref{Preprocessor Options, , Options Controlling the Preprocessor,
+gcc.info, Using GNU CC}, for details.
+
+@cindex @code{sed} (shell command)
+The purpose of the @code{sed} command is to translate (for example):
+
+@example
+main.o : main.c defs.h
+@end example
+
+@noindent
+into:
+
+@example
+main.o main.d : main.c defs.h
+@end example
+
+@noindent
+@cindex @code{.d}
+This makes each @samp{.d} file depend on all the source and header files
+that the corresponding @samp{.o} file depends on.  @code{make} then
+knows it must regenerate the prerequisites whenever any of the source or
+header files changes.
+
+Once you've defined the rule to remake the @samp{.d} files,
+you then use the @code{include} directive to read them all in.
+@xref{Include}.  For example:
+
+@example
+@group
+sources = foo.c bar.c

+Normally @code{make} prints each command line before it is executed.
+We call this @dfn{echoing} because it gives the appearance that you
+are typing the commands yourself.
+
+When a line starts with @samp{@@}, the echoing of that line is suppressed.
+The @samp{@@} is discarded before the command is passed to the shell.
+Typically you would use this for a command whose only effect is to print
+something, such as an @code{echo} command to indicate progress through
+the makefile:

+When @code{make} is given the flag @samp{-n} or @samp{--just-print}
+it only echoes commands, it won't execute them.  @xref{Options Summary,

+When it is time to execute commands to update a target, they are executed

+
+@cindex @code{cd} (shell command)
+@strong{Please note:} this implies that shell commands such as @code{cd}

+following command lines on those systems.}  If you want to use @code{cd}
+to affect the next command, put the two on a single line with a
+semicolon between them.  Then @code{make} will consider them a single
+command and pass them, together, to a shell which will execute them in
+sequence.  For example:
+
+@example
+foo : bar/lose
+        cd bar; gobble lose > ../foo

+If you would like to split a single shell command into multiple lines of
+text, you must use a backslash at the end of all but the last subline.
+Such a sequence of lines is combined into a single line, by deleting the
+backslash-newline sequences, before passing it to the shell.  Thus, the
+following is equivalent to the preceding example:
+
+@example
+@group
+foo : bar/lose
+        cd bar;  \
+        gobble lose > ../foo
+@end group

+
+@vindex SHELL
+The program used as the shell is taken from the variable @code{SHELL}.
+By default, the program @file{/bin/sh} is used.
+
+@vindex COMSPEC
+On MS-DOS, if @code{SHELL} is not set, the value of the variable
+@code{COMSPEC} (which is always set) is used instead.
+
+@cindex @code{SHELL}, MS-DOS specifics
+The processing of lines that set the variable @code{SHELL} in Makefiles
+is different on MS-DOS.  The stock shell, @file{command.com}, is
+ridiculously limited in its functionality and many users of @code{make}
+tend to install a replacement shell.  Therefore, on MS-DOS, @code{make}
+examines the value of @code{SHELL}, and changes its behavior based on
+whether it points to a Unix-style or DOS-style shell.  This allows
+reasonable functionality even if @code{SHELL} points to
+@file{command.com}.
+
+If @code{SHELL} points to a Unix-style shell, @code{make} on MS-DOS
+additionally checks whether that shell can indeed be found; if not, it
+ignores the line that sets @code{SHELL}.  In MS-DOS, GNU @code{make}
+searches for the shell in the following places:
+
+@enumerate
+@item
+In the precise place pointed to by the value of @code{SHELL}.  For
+example, if the makefile specifies @samp{SHELL = /bin/sh}, @code{make}
+will look in the directory @file{/bin} on the current drive.
+
+@item
+In the current directory.
+
+@item
+In each of the directories in the @code{PATH} variable, in order.
+
+@end enumerate
+
+In every directory it examines, @code{make} will first look for the
+specific file (@file{sh} in the example above).  If this is not found,
+it will also look in that directory for that file with one of the known
+extensions which identify executable files.  For example @file{.exe},
+@file{.com}, @file{.bat}, @file{.btm}, @file{.sh}, and some others.
+
+If any of these attempts is successful, the value of @code{SHELL} will
+be set to the full pathname of the shell as found.  However, if none of
+these is found, the value of @code{SHELL} will not be changed, and thus
+the line that sets it will be effectively ignored.  This is so
+@code{make} will only support features specific to a Unix-style shell if
+such a shell is actually installed on the system where @code{make} runs.
+
+Note that this extended search for the shell is limited to the cases
+where @code{SHELL} is set from the Makefile; if it is set in the
+environment or command line, you are expected to set it to the full
+pathname of the shell, exactly as things are on Unix.
+
+The effect of the above DOS-specific processing is that a Makefile that
+says @samp{SHELL = /bin/sh} (as many Unix makefiles do), will work
+on MS-DOS unaltered if you have e.g. @file{sh.exe} installed in some
+directory along your @code{PATH}.
+
+@cindex environment, @code{SHELL} in
+Unlike most variables, the variable @code{SHELL} is never set from the
+environment.  This is because the @code{SHELL} environment variable is
+used to specify your personal choice of shell program for interactive
+use.  It would be very bad for personal choices like this to affect the
+functioning of makefiles.  @xref{Environment, ,Variables from the
+Environment}.  However, on MS-DOS and MS-Windows the value of
+@code{SHELL} in the environment @strong{is} used, since on those systems
+most users do not set this variable, and therefore it is most likely set
+specifically to be used by @code{make}.  On MS-DOS, if the setting of
+@code{SHELL} is not suitable for @code{make}, you can set the variable
+@code{MAKESHELL} to the shell that @code{make} should use; this will
+override the value of @code{SHELL}.

+@cindex job slots
+@cindex @code{-j}
+@cindex @code{--jobs}
+
+GNU @code{make} knows how to execute several commands at once.
+Normally, @code{make} will execute only one command at a time, waiting
+for it to finish before executing the next.  However, the @samp{-j} or
+@samp{--jobs} option tells @code{make} to execute many commands
+simultaneously.@refill
+
+On MS-DOS, the @samp{-j} option has no effect, since that system doesn't
+support multi-processing.
+
+If the @samp{-j} option is followed by an integer, this is the number of
+commands to execute at once; this is called the number of @dfn{job slots}.
+If there is nothing looking like an integer after the @samp{-j} option,
+there is no limit on the number of job slots.  The default number of job
+slots is one, which means serial execution (one thing at a time).
+
+One unpleasant consequence of running several commands simultaneously is
+that output generated by the commands appears whenever each command
+sends it, so messages from different commands may be interspersed.
+
+Another problem is that two processes cannot both take input from the
+same device; so to make sure that only one command tries to take input
+from the terminal at once, @code{make} will invalidate the standard
+input streams of all but one running command.  This means that
+attempting to read from standard input will usually be a fatal error (a
+@samp{Broken pipe} signal) for most child processes if there are
+several.
+@cindex broken pipe
+@cindex standard input
+
+It is unpredictable which command will have a valid standard input stream
+(which will come from the terminal, or wherever you redirect the standard
+input of @code{make}).  The first command run will always get it first, and
+the first command started after that one finishes will get it next, and so
+on.
+
+We will change how this aspect of @code{make} works if we find a better
+alternative.  In the mean time, you should not rely on any command using
+standard input at all if you are using the parallel execution feature; but
+if you are not using this feature, then standard input works normally in
+all commands.
+
+Finally, handling recursive @code{make} invocations raises issues.  For
+more information on this, see
+@ref{Options/Recursion, ,Communicating Options to a Sub-@code{make}}.
+
+If a command fails (is killed by a signal or exits with a nonzero
+status), and errors are not ignored for that command
+(@pxref{Errors, ,Errors in Commands}),
+the remaining command lines to remake the same target will not be run.
+If a command fails and the @samp{-k} or @samp{--keep-going}
+option was not given

+When the system is heavily loaded, you will probably want to run fewer jobs
+than when it is lightly loaded.  You can use the @samp{-l} option to tell
+@code{make} to limit the number of jobs to run at once, based on the load
+average.  The @samp{-l} or @samp{--max-load}
+option is followed by a floating-point number.  For
+example,

+above 2.5.  The @samp{-l} option with no following number removes the
+load limit, if one was given with a previous @samp{-l} option.@refill
+
+More precisely, when @code{make} goes to start up a job, and it already has
+at least one job running, it checks the current load average; if it is not
+lower than the limit given with @samp{-l}, @code{make} waits until the load
+average goes below that limit, or until all the other jobs finish.

+@cindex exit status (errors)
+
+After each shell command returns, @code{make} looks at its exit status.
+If the command completed successfully, the next command line is executed
+in a new shell; after the last command line is finished, the rule is
+finished.
+
+If there is an error (the exit status is nonzero), @code{make} gives up on
+the current rule, and perhaps on all rules.
+
+Sometimes the failure of a certain command does not indicate a problem.
+For example, you may use the @code{mkdir} command to ensure that a
+directory exists.  If the directory already exists, @code{mkdir} will
+report an error, but you probably want @code{make} to continue regardless.
+
+@cindex @code{-} (in commands)
+To ignore errors in a command line, write a @samp{-} at the beginning of
+the line's text (after the initial tab).  The @samp{-} is discarded before
+the command is passed to the shell for execution.
+
+For example,
+
+@example
+@group
+clean:
+        -rm -f *.o
+@end group
+@end example
+@cindex @code{rm} (shell command)
+
+@noindent
+This causes @code{rm} to continue even if it is unable to remove a file.
+
+@cindex @code{-i}
+@cindex @code{--ignore-errors}
+@findex .IGNORE
+When you run @code{make} with the @samp{-i} or @samp{--ignore-errors}
+flag, errors are ignored in all commands of all rules.  A rule in the
+makefile for the special target @code{.IGNORE} has the same effect, if
+there are no prerequisites.  These ways of ignoring errors are obsolete
+because @samp{-} is more flexible.
+
+When errors are to be ignored, because of either a @samp{-} or the
+@samp{-i} flag, @code{make} treats an error return just like success,
+except that it prints out a message that tells you the status code
+the command exited with, and says that the error has been ignored.
+
+When an error happens that @code{make} has not been told to ignore,
+it implies that the current target cannot be correctly remade, and neither
+can any other that depends on it either directly or indirectly.  No further
+commands will be executed for these targets, since their preconditions
+have not been achieved.
+
+
+@cindex @code{-k}
+@cindex @code{--keep-going}
+Normally @code{make} gives up immediately in this circumstance, returning a
+nonzero status.  However, if the @samp{-k} or @samp{--keep-going}
+flag is specified, @code{make}
+continues to consider the other prerequisites of the pending targets,
+remaking them if necessary, before it gives up and returns nonzero status.
+For example, after an error in compiling one object file, @samp{make -k}
+will continue compiling other object files even though it already knows
+that linking them will be impossible.  @xref{Options Summary, ,Summary of Options}.
+
+The usual behavior assumes that your purpose is to get the specified
+targets up to date; once @code{make} learns that this is impossible, it
+might as well report the failure immediately.  The @samp{-k} option says
+that the real purpose is to test as many of the changes made in the
+program as possible, perhaps to find several independent problems so
+that you can correct them all before the next attempt to compile.  This
+is why Emacs' @code{compile} command passes the @samp{-k} flag by
+default.

+Usually when a command fails, if it has changed the target file at all,
+the file is corrupted and cannot be used---or at least it is not
+completely updated.  Yet the file's time stamp says that it is now up to
+date, so the next time @code{make} runs, it will not try to update that
+file.  The situation is just the same as when the command is killed by a
+signal; @pxref{Interrupts}.  So generally the right thing to do is to
+delete the target file if the command fails after beginning to change
+the file.  @code{make} will do this if @code{.DELETE_ON_ERROR} appears
+as a target.  This is almost always what you want @code{make} to do, but
+it is not historical practice; so for compatibility, you must explicitly
+request it.

+
+If @code{make} gets a fatal signal while a command is executing, it may
+delete the target file that the command was supposed to update.  This is
+done if the target file's last-modification time has changed since
+@code{make} first checked it.
+
+The purpose of deleting the target is to make sure that it is remade from
+scratch when @code{make} is next run.  Why is this?  Suppose you type
+@kbd{Ctrl-c} while a compiler is running, and it has begun to write an
+object file @file{foo.o}.  The @kbd{Ctrl-c} kills the compiler, resulting
+in an incomplete file whose last-modification time is newer than the source
+file @file{foo.c}.  But @code{make} also receives the @kbd{Ctrl-c} signal
+and deletes this incomplete file.  If @code{make} did not do this, the next
+invocation of @code{make} would think that @file{foo.o} did not require
+updating---resulting in a strange error message from the linker when it
+tries to link an object file half of which is missing.
+
+@findex .PRECIOUS
+You can prevent the deletion of a target file in this way by making the
+special target @code{.PRECIOUS} depend on it.  Before remaking a target,
+@code{make} checks to see whether it appears on the prerequisites of
+@code{.PRECIOUS}, and thereby decides whether the target should be deleted
+if a signal happens.  Some reasons why you might do this are that the
+target is updated in some atomic fashion, or exists only to record a
+modification-time (its contents do not matter), or must exist at all
+times to prevent other sorts of trouble.

+Recursive use of @code{make} means using @code{make} as a command in a
+makefile.  This technique is useful when you want separate makefiles for
+various subsystems that compose a larger system.  For example, suppose you
+have a subdirectory @file{subdir} which has its own makefile, and you would
+like the containing directory's makefile to run @code{make} on the
+subdirectory.  You can do it by writing this:

+You can write recursive @code{make} commands just by copying this example,
+but there are many things to know about how they work and why, and about
+how the sub-@code{make} relates to the top-level @code{make}.  You may

+the pathname of the current working directory.  This value is never
+touched by @code{make} again: in particular note that if you include
+files from other directories the value of @code{CURDIR} does not
+change.  The value has the same precedence it would have if it were
+set in the makefile (by default, an environment variable @code{CURDIR}
+will not override this value).  Note that setting this variable has no
+impact on the operation of @code{make} (it does not cause @code{make}

+        cd subdir && $(MAKE)

+
+The value of this variable is the file name with which @code{make} was

+is @samp{cd subdir && /bin/make}.  If you use a special version of
+@code{make} to run the top-level makefile, the same special version will be
+executed for recursive invocations.
+@cindex @code{cd} (shell command)

+As a special feature, using the variable @code{MAKE} in the commands of
+a rule alters the effects of the @samp{-t} (@samp{--touch}), @samp{-n}
+(@samp{--just-print}), or @samp{-q} (@w{@samp{--question}}) option.
+Using the @code{MAKE} variable has the same effect as using a @samp{+}

+
+Consider the command @samp{make -t} in the above example.  (The
+@samp{-t} option marks targets as up to date without actually running
+any commands; see @ref{Instead of Execution}.)  Following the usual
+definition of @samp{-t}, a @samp{make -t} command in the example would
+create a file named @file{subsystem} and do nothing else.  What you
+really want it to do is run @samp{@w{cd subdir &&} @w{make -t}}; but that would

+Variable values of the top-level @code{make} can be passed to the

+makefile unless you use the @samp{-e} switch (@pxref{Options Summary,
+,Summary of Options}).@refill
+
+To pass down, or @dfn{export}, a variable, @code{make} adds the variable
+and its value to the environment for running each command.  The
+sub-@code{make}, in turn, uses the environment to initialize its table
+of variable values.  @xref{Environment, ,Variables from the
+Environment}.
+
+Except by explicit request, @code{make} exports a variable only if it
+is either defined in the environment initially or set on the command
+line, and if its name consists only of letters, numbers, and underscores.
+Some shells cannot cope with environment variable names consisting of
+characters other than letters, numbers, and underscores.
+
+The special variables @code{SHELL} and @code{MAKEFLAGS} are always
+exported (unless you unexport them).
+@code{MAKEFILES} is exported if you set it to anything.

+
+You may notice that the @code{export} and @code{unexport} directives
+work in @code{make} in the same way they work in the shell, @code{sh}.
+
+If you want all variables to be exported by default, you can use
+@code{export} by itself:
+
+@example
+export
+@end example
+
+@noindent
+This tells @code{make} that variables which are not explicitly mentioned
+in an @code{export} or @code{unexport} directive should be exported.
+Any variable given in an @code{unexport} directive will still @emph{not}
+be exported.  If you use @code{export} by itself to export variables by
+default, variables whose names contain characters other than
+alphanumerics and underscores will not be exported unless specifically
+mentioned in an @code{export} directive.@refill
+
+@findex .EXPORT_ALL_VARIABLES
+The behavior elicited by an @code{export} directive by itself was the
+default in older versions of GNU @code{make}.  If your makefiles depend
+on this behavior and you want to be compatible with old versions of
+@code{make}, you can write a rule for the special target
+@code{.EXPORT_ALL_VARIABLES} instead of using the @code{export} directive.
+This will be ignored by old @code{make}s, while the @code{export}
+directive will cause a syntax error.@refill
+@cindex compatibility in exporting
+
+Likewise, you can use @code{unexport} by itself to tell @code{make}
+@emph{not} to export variables by default.  Since this is the default
+behavior, you would only need to do this if @code{export} had been used
+by itself earlier (in an included makefile, perhaps).  You
+@strong{cannot} use @code{export} and @code{unexport} by themselves to
+have variables exported for some commands and not for others.  The last
+@code{export} or @code{unexport} directive that appears by itself
+determines the behavior for the entire run of @code{make}.@refill
+
+@vindex MAKELEVEL
+@cindex recursion, level of
+As a special feature, the variable @code{MAKELEVEL} is changed when it
+is passed down from level to level.  This variable's value is a string
+which is the depth of the level as a decimal number.  The value is
+@samp{0} for the top-level @code{make}; @samp{1} for a sub-@code{make},
+@samp{2} for a sub-sub-@code{make}, and so on.  The incrementation
+happens when @code{make} sets up the environment for a command.@refill
+
+The main use of @code{MAKELEVEL} is to test it in a conditional
+directive (@pxref{Conditionals, ,Conditional Parts of Makefiles}); this
+way you can write a makefile that behaves one way if run recursively and
+another way if run directly by you.@refill
+
+@vindex MAKEFILES
+You can use the variable @code{MAKEFILES} to cause all sub-@code{make}
+commands to use additional makefiles.  The value of @code{MAKEFILES} is
+a whitespace-separated list of file names.  This variable, if defined in
+the outer-level makefile, is passed down through the environment; then
+it serves as a list of extra makefiles for the sub-@code{make} to read
+before the usual or specified ones.  @xref{MAKEFILES Variable, ,The

+If you set it to some numeric value @samp{N} and your operating system
+supports it (most any UNIX system will; others typically won't), the
+parent @code{make} and all the sub-@code{make}s will communicate to
+ensure that there are only @samp{N} jobs running at the same time
+between them all.  Note that any job that is marked recursive
+(@pxref{Instead of Execution, ,Instead of Executing the Commands})
+doesn't count against the total jobs (otherwise we could get @samp{N}
+sub-@code{make}s running and have no slots left over for any real work!)
+
+If your operating system doesn't support the above communication, then
+@samp{-j 1} is always put into @code{MAKEFLAGS} instead of the value you
+specified.  This is because if the @w{@samp{-j}} option were passed down
+to sub-@code{make}s, you would get many more jobs running in parallel
+than you asked for.  If you give @samp{-j} with no numeric argument,
+meaning to run as many jobs as possible in parallel, this is passed
+down, since multiple infinities are no more than one.@refill
+
+If you do not want to pass the other flags down, you must change the

+
+@vindex MAKEOVERRIDES
+The command line variable definitions really appear in the variable

+pass down the command line variable definitions, you can reset
+@code{MAKEOVERRIDES} to empty, like this:
+
+@example
+MAKEOVERRIDES =

+@cindex Arg list too long
+@cindex E2BIG
+This is not usually useful to do.  However, some systems have a small

+
+@vindex MFLAGS
+A similar variable @code{MFLAGS} exists also, for historical
+compatibility.  It has the same value as @code{MAKEFLAGS} except that it
+does not contain the command line variable definitions, and it always
+begins with a hyphen unless it is empty (@code{MAKEFLAGS} begins with a
+hyphen only when it begins with an option that has no single-letter
+version, such as @samp{--warn-undefined-variables}).  @code{MFLAGS} was
+traditionally used explicitly in the recursive @code{make} command, like
+this:
+
+@example
+subsystem:
+        cd subdir && $(MAKE) $(MFLAGS)
+@end example
+
+@noindent
+but now @code{MAKEFLAGS} makes this usage redundant.  If you want your
+makefiles to be compatible with old @code{make} programs, use this
+technique; it will work fine with more modern @code{make} versions too.

+The @code{MAKEFLAGS} variable can also be useful if you want to have
+certain options, such as @samp{-k} (@pxref{Options Summary, ,Summary of
+Options}), set each time you run @code{make}.  You simply put a value for
+@code{MAKEFLAGS} in your environment.  You can also set @code{MAKEFLAGS} in
+a makefile, to specify additional flags that should also be in effect for
+that makefile.  (Note that you cannot use @code{MFLAGS} this way.  That
+variable is set only for compatibility; @code{make} does not interpret a
+value you set for it in any way.)
+
+When @code{make} interprets the value of @code{MAKEFLAGS} (either from the
+environment or from a makefile), it first prepends a hyphen if the value
+does not already begin with one.  Then it chops the value into words
+separated by blanks, and parses these words as if they were options given
+on the command line (except that @samp{-C}, @samp{-f}, @samp{-h},
+@samp{-o}, @samp{-W}, and their long-named versions are ignored; and there
+is no error for an invalid option).
+
+If you do put @code{MAKEFLAGS} in your environment, you should be sure not
+to include any options that will drastically affect the actions of
+@code{make} and undermine the purpose of makefiles and of @code{make}
+itself.  For instance, the @samp{-t}, @samp{-n}, and @samp{-q} options, if

+@node Sequences, Empty Commands, Recursion, Commands
+@section Defining Canned Command Sequences
+@cindex sequences of commands
+@cindex commands, sequences of
+
+When the same sequence of commands is useful in making various targets, you
+can define it as a canned sequence with the @code{define} directive, and
+refer to the canned sequence from the rules for those targets.  The canned
+sequence is actually a variable, so the name must not conflict with other
+variable names.
+
+Here is an example of defining a canned sequence of commands:
+
+@example
+define run-yacc
+yacc $(firstword $^)
+mv y.tab.c $@@
+endef
+@end example
+@cindex @code{yacc}
+
+@noindent
+Here @code{run-yacc} is the name of the variable being defined;
+@code{endef} marks the end of the definition; the lines in between are the
+commands.  The @code{define} directive does not expand variable references
+and function calls in the canned sequence; the @samp{$} characters,
+parentheses, variable names, and so on, all become part of the value of the
+variable you are defining.
+@xref{Defining, ,Defining Variables Verbatim},
+for a complete explanation of @code{define}.
+
+The first command in this example runs Yacc on the first prerequisite of
+whichever rule uses the canned sequence.  The output file from Yacc is
+always named @file{y.tab.c}.  The second command moves the output to the
+rule's target file name.
+
+To use the canned sequence, substitute the variable into the commands of a
+rule.  You can substitute it like any other variable
+(@pxref{Reference, ,Basics of Variable References}).
+Because variables defined by @code{define} are recursively expanded
+variables, all the variable references you wrote inside the @code{define}
+are expanded now.  For example:
+
+@example
+foo.c : foo.y
+        $(run-yacc)
+@end example
+
+@noindent
+@samp{foo.y} will be substituted for the variable @samp{$^} when it occurs in
+@code{run-yacc}'s value, and @samp{foo.c} for @samp{$@@}.@refill
+
+This is a realistic example, but this particular one is not needed in
+practice because @code{make} has an implicit rule to figure out these
+commands based on the file names involved
+(@pxref{Implicit Rules, ,Using Implicit Rules}).
+
+@cindex @@, and @code{define}
+@cindex -, and @code{define}
+@cindex +, and @code{define}
+In command execution, each line of a canned sequence is treated just as
+if the line appeared on its own in the rule, preceded by a tab.  In
+particular, @code{make} invokes a separate subshell for each line.  You
+can use the special prefix characters that affect command lines
+(@samp{@@}, @samp{-}, and @samp{+}) on each line of a canned sequence.
+@xref{Commands, ,Writing the Commands in Rules}.
+For example, using this canned sequence:
+
+@example
+define frobnicate
+@@echo "frobnicating target $@@"
+frob-step-1 $< -o $@@-step-1
+frob-step-2 $@@-step-1 -o $@@
+endef
+@end example
+
+@noindent
+@code{make} will not echo the first line, the @code{echo} command.
+But it @emph{will} echo the following two command lines.
+
+On the other hand, prefix characters on the command line that refers to
+a canned sequence apply to every line in the sequence.  So the rule:
+
+@example
+frob.out: frob.in
+        @@$(frobnicate)
+@end example
+
+@noindent
+does not echo @emph{any} commands.

+@section Using Empty Commands

+It is sometimes useful to define commands which do nothing.  This is done
+simply by giving a command that consists of nothing but whitespace.  For
+example:
+
+@example
+target: ;
+@end example
+
+@noindent
+defines an empty command string for @file{target}.  You could also use a
+line beginning with a tab character to define an empty command string,
+but this would be confusing because such a line looks empty.
+
+@findex .DEFAULT@r{, and empty commands}
+You may be wondering why you would want to define a command string that
+does nothing.  The only reason this is useful is to prevent a target
+from getting implicit commands (from implicit rules or the
+@code{.DEFAULT} special target; @pxref{Implicit Rules} and
+@pxref{Last Resort, ,Defining Last-Resort Default Rules}).@refill
+
+@c !!! another reason is for canonical stamp files:

+@example
+foo: stamp-foo ;
+stamp-foo: foo.in
+        create foo frm foo.in
+        touch $@
+@end example
+@end ignore
+
+You may be inclined to define empty command strings for targets that are
+not actual files, but only exist so that their prerequisites can be
+remade.  However, this is not the best way to do that, because the
+prerequisites may not be remade properly if the target file actually does exist.

+@cindex variable
+@cindex value
+@cindex recursive variable expansion
+@cindex simple variable expansion
+
+A @dfn{variable} is a name defined in a makefile to represent a string
+of text, called the variable's @dfn{value}.  These values are
+substituted by explicit request into targets, prerequisites, commands,
+and other parts of the makefile.  (In some other versions of @code{make},
+variables are called @dfn{macros}.)
+@cindex macro
+
+Variables and functions in all parts of a makefile are expanded when
+read, except for the shell commands in rules, the right-hand sides of
+variable definitions using @samp{=}, and the bodies of variable
+definitions using the @code{define} directive.@refill
+
+Variables can represent lists of file names, options to pass to compilers,
+programs to run, directories to look in for source files, directories to
+write output in, or anything else you can imagine.
+
+A variable name may be any sequence of characters not containing @samp{:},
+@samp{#}, @samp{=}, or leading or trailing whitespace.  However,
+variable names containing characters other than letters, numbers, and
+underscores should be avoided, as they may be given special meanings in the
+future, and with some shells they cannot be passed through the environment to a
+sub-@code{make}
+(@pxref{Variables/Recursion, ,Communicating Variables to a Sub-@code{make}}).
+
+Variable names are case-sensitive.  The names @samp{foo}, @samp{FOO},
+and @samp{Foo} all refer to different variables.
+
+It is traditional to use upper case letters in variable names, but we
+recommend using lower case letters for variable names that serve internal
+purposes in the makefile, and reserving upper case for parameters that
+control implicit rules or for parameters that the user should override with
+command options (@pxref{Overriding, ,Overriding Variables}).
+
+A few variables have names that are a single punctuation character or
+just a few characters.  These are the @dfn{automatic variables}, and
+they have particular specialized uses.  @xref{Automatic Variables}.

+@cindex reference to variables
+@cindex @code{$}, in variable reference
+@cindex dollar sign (@code{$}), in variable reference
+
+To substitute a variable's value, write a dollar sign followed by the name
+of the variable in parentheses or braces: either @samp{$(foo)} or
+@samp{$@{foo@}} is a valid reference to the variable @code{foo}.  This
+special significance of @samp{$} is why you must write @samp{$$} to have
+the effect of a single dollar sign in a file name or command.
+
+Variable references can be used in any context: targets, prerequisites,
+commands, most directives, and new variable values.  Here is an
+example of a common case, where a variable holds the names of all the
+object files in a program:
+
+@example
+@group
+objects = program.o foo.o utils.o
+program : $(objects)
+        cc -o program $(objects)
+
+$(objects) : defs.h
+@end group
+@end example
+
+Variable references work by strict textual substitution.  Thus, the rule
+
+@example
+@group
+foo = c
+prog.o : prog.$(foo)
+        $(foo)$(foo) -$(foo) prog.$(foo)
+@end group
+@end example
+
+@noindent
+could be used to compile a C program @file{prog.c}.  Since spaces before
+the variable value are ignored in variable assignments, the value of
+@code{foo} is precisely @samp{c}.  (Don't actually write your makefiles
+this way!)
+
+A dollar sign followed by a character other than a dollar sign,
+open-parenthesis or open-brace treats that single character as the
+variable name.  Thus, you could reference the variable @code{x} with
+@samp{$x}.  However, this practice is strongly discouraged, except in
+the case of the automatic variables (@pxref{Automatic Variables}).
+
+@node Flavors, Advanced, Reference, Using Variables
+@section The Two Flavors of Variables
+@cindex flavors of variables
+@cindex recursive variable expansion
+@cindex variables, flavors
+@cindex recursively expanded variables
+@cindex variables, recursively expanded
+
+There are two ways that a variable in GNU @code{make} can have a value;
+we call them the two @dfn{flavors} of variables.  The two flavors are
+distinguished in how they are defined and in what they do when expanded.
+
+@cindex =
+The first flavor of variable is a @dfn{recursively expanded} variable.
+Variables of this sort are defined by lines using @samp{=}
+(@pxref{Setting, ,Setting Variables}) or by the @code{define} directive
+(@pxref{Defining, ,Defining Variables Verbatim}).  The value you specify
+is installed verbatim; if it contains references to other variables,
+these references are expanded whenever this variable is substituted (in
+the course of expanding some other string).  When this happens, it is
+called @dfn{recursive expansion}.@refill
+
+For example,
+
+@example
+foo = $(bar)
+bar = $(ugh)
+ugh = Huh?
+
+all:;echo $(foo)
+@end example
+
+@noindent
+will echo @samp{Huh?}: @samp{$(foo)} expands to @samp{$(bar)} which
+expands to @samp{$(ugh)} which finally expands to @samp{Huh?}.@refill
+
+This flavor of variable is the only sort supported by other versions of
+@code{make}.  It has its advantages and its disadvantages.  An advantage
+(most would say) is that:
+
+@example
+CFLAGS = $(include_dirs) -O
+include_dirs = -Ifoo -Ibar
+@end example
+
+@noindent
+will do what was intended: when @samp{CFLAGS} is expanded in a command,
+it will expand to @samp{-Ifoo -Ibar -O}.  A major disadvantage is that you
+cannot append something on the end of a variable, as in
+
+@example
+CFLAGS = $(CFLAGS) -O
+@end example
+
+@noindent
+because it will cause an infinite loop in the variable expansion.
+(Actually @code{make} detects the infinite loop and reports an error.)
+@cindex loops in variable expansion
+@cindex variables, loops in expansion
+
+Another disadvantage is that any functions
+(@pxref{Functions, ,Functions for Transforming Text})
+referenced in the definition will be executed every time the variable is
+expanded.  This makes @code{make} run slower; worse, it causes the
+@code{wildcard} and @code{shell} functions to give unpredictable results
+because you cannot easily control when they are called, or even how many
+times.
+
+To avoid all the problems and inconveniences of recursively expanded
+variables, there is another flavor: simply expanded variables.
+
+@cindex simply expanded variables
+@cindex variables, simply expanded
+@cindex :=
+@dfn{Simply expanded variables} are defined by lines using @samp{:=}
+(@pxref{Setting, ,Setting Variables}).
+The value of a simply expanded variable is scanned
+once and for all, expanding any references to other variables and
+functions, when the variable is defined.  The actual value of the simply
+expanded variable is the result of expanding the text that you write.
+It does not contain any references to other variables; it contains their
+values @emph{as of the time this variable was defined}.  Therefore,
+
+@example
+x := foo
+y := $(x) bar
+x := later
+@end example
+
+@noindent
+is equivalent to
+
+@example
+y := foo bar
+x := later
+@end example
+
+When a simply expanded variable is referenced, its value is substituted
+verbatim.
+
+Here is a somewhat more complicated example, illustrating the use of

+Simply expanded variables generally make complicated makefile programming

+You can also use them to introduce controlled leading whitespace into

+protecting them with variable references, like this:
+
+@example
+nullstring :=
+space := $(nullstring) # end of the line
+@end example
+
+@noindent
+Here the value of the variable @code{space} is precisely one space.  The
+comment @w{@samp{# end of the line}} is included here just for clarity.
+Since trailing space characters are @emph{not} stripped from variable
+values, just a space at the end of the line would have the same effect
+(but be rather hard to read).  If you put whitespace at the end of a
+variable value, it is a good idea to put a comment like that at the end
+of the line to make your intent clear.  Conversely, if you do @emph{not}
+want any whitespace characters at the end of your variable value, you
+must remember not to put a random comment on the end of the line after
+some whitespace, such as this:
+
+@example
+dir := /foo/bar    # directory to put the frobs in
+@end example
+
+@noindent
+Here the value of the variable @code{dir} is @w{@samp{/foo/bar    }}

+A @dfn{substitution reference} substitutes the value of a variable with
+alterations that you specify.  It has the form
+@samp{$(@var{var}:@var{a}=@var{b})} (or
+@samp{$@{@var{var}:@var{a}=@var{b}@}}) and its meaning is to take the value
+of the variable @var{var}, replace every @var{a} at the end of a word with
+@var{b} in that value, and substitute the resulting string.
+
+When we say ``at the end of a word'', we mean that @var{a} must appear
+either followed by whitespace or at the end of the value in order to be
+replaced; other occurrences of @var{a} in the value are unaltered.  For
+example:@refill
+
+@example
+foo := a.o b.o c.o
+bar := $(foo:.o=.c)

+sets @samp{bar} to @samp{a.c b.c c.c}.  @xref{Setting, ,Setting Variables}.

+@cindex variables, computed names
+@cindex variables, nested references
+@cindex variables, @samp{$} in name
+@cindex @code{$}, in variable name
+@cindex dollar sign (@code{$}), in variable name
+
+Computed variable names are a complicated concept needed only for
+sophisticated makefile programming.  For most purposes you need not
+consider them, except to know that making a variable with a dollar sign
+in its name might have strange results.  However, if you are the type
+that wants to understand everything, or you are actually interested in
+what they do, read on.
+
+Variables may be referenced inside the name of a variable.  This is
+called a @dfn{computed variable name} or a @dfn{nested variable
+reference}.  For example,
+
+@example
+x = y
+y = z
+a := $($(x))
+@end example
+
+@noindent
+defines @code{a} as @samp{z}: the @samp{$(x)} inside @samp{$($(x))} expands
+to @samp{y}, so @samp{$($(x))} expands to @samp{$(y)} which in turn expands
+to @samp{z}.  Here the name of the variable to reference is not stated
+explicitly; it is computed by expansion of @samp{$(x)}.  The reference
+@samp{$(x)} here is nested within the outer variable reference.
+
+The previous example shows two levels of nesting, but any number of levels
+is possible.  For example, here are three levels:
+
+@example
+x = y
+y = z
+z = u
+a := $($($(x)))
+@end example
+
+@noindent
+Here the innermost @samp{$(x)} expands to @samp{y}, so @samp{$($(x))}
+expands to @samp{$(y)} which in turn expands to @samp{z}; now we have
+@samp{$(z)}, which becomes @samp{u}.
+
+References to recursively-expanded variables within a variable name are
+reexpanded in the usual fashion.  For example:
+
+@example
+x = $(y)
+y = z
+z = Hello
+a := $($(x))
+@end example
+
+@noindent
+defines @code{a} as @samp{Hello}: @samp{$($(x))} becomes @samp{$($(y))}
+which becomes @samp{$(z)} which becomes @samp{Hello}.
+
+Nested variable references can also contain modified references and
+function invocations (@pxref{Functions, ,Functions for Transforming Text}),
+just like any other reference.
+For example, using the @code{subst} function
+(@pxref{Text Functions, ,Functions for String Substitution and Analysis}):
+
+@example
+@group
+x = variable1
+variable2 := Hello
+y = $(subst 1,2,$(x))
+z = y
+a := $($($(z)))
+@end group
+@end example
+
+@noindent
+eventually defines @code{a} as @samp{Hello}.  It is doubtful that anyone
+would ever want to write a nested reference as convoluted as this one, but
+it works: @samp{$($($(z)))} expands to @samp{$($(y))} which becomes
+@samp{$($(subst 1,2,$(x)))}.  This gets the value @samp{variable1} from
+@code{x} and changes it by substitution to @samp{variable2}, so that the
+entire string becomes @samp{$(variable2)}, a simple variable reference
+whose value is @samp{Hello}.@refill
+
+A computed variable name need not consist entirely of a single variable
+reference.  It can contain several variable references, as well as some
+invariant text.  For example,
+
+@example
+@group
+a_dirs := dira dirb
+1_dirs := dir1 dir2
+@end group
+
+@group
+a_files := filea fileb
+1_files := file1 file2
+@end group
+
+@group
+ifeq "$(use_a)" "yes"
+a1 := a
+else
+a1 := 1
+endif
+@end group
+
+@group
+ifeq "$(use_dirs)" "yes"
+df := dirs
+else
+df := files
+endif
+
+dirs := $($(a1)_$(df))
+@end group
+@end example
+
+@noindent
+will give @code{dirs} the same value as @code{a_dirs}, @code{1_dirs},
+@code{a_files} or @code{1_files} depending on the settings of @code{use_a}
+and @code{use_dirs}.@refill
+
+Computed variable names can also be used in substitution references:
+
+@example
+@group
+a_objects := a.o b.o c.o
+1_objects := 1.o 2.o 3.o
+
+sources := $($(a1)_objects:.o=.c)
+@end group
+@end example
+
+@noindent
+defines @code{sources} as either @samp{a.c b.c c.c} or @samp{1.c 2.c 3.c},
+depending on the value of @code{a1}.
+
+The only restriction on this sort of use of nested variable references
+is that they cannot specify part of the name of a function to be called.
+This is because the test for a recognized function name is done before
+the expansion of nested references.  For example,
+
+@example
+@group
+ifdef do_sort
+func := sort
+else
+func := strip
+endif
+@end group
+
+@group
+bar := a d b g q c
+@end group
+
+@group
+foo := $($(func) $(bar))
+@end group
+@end example
+
+@noindent
+attempts to give @samp{foo} the value of the variable @samp{sort a d b g
+q c} or @samp{strip a d b g q c}, rather than giving @samp{a d b g q c}
+as the argument to either the @code{sort} or the @code{strip} function.
+This restriction could be removed in the future if that change is shown
+to be a good idea.
+
+You can also use computed variable names in the left-hand side of a
+variable assignment, or in a @code{define} directive, as in:
+
+@example
+dir = foo
+$(dir)_sources := $(wildcard $(dir)/*.c)
+define $(dir)_print
+lpr $($(dir)_sources)
+endef
+@end example
+
+@noindent
+This example defines the variables @samp{dir}, @samp{foo_sources}, and
+@samp{foo_print}.
+

+@dfn{recursively expanded variables}

+
+To set a variable from the makefile, write a line starting with the
+variable name followed by @samp{=} or @samp{:=}.  Whatever follows the
+@samp{=} or @samp{:=} on the line becomes the value.  For example,
+
+@example
+objects = main.o foo.o bar.o utils.o
+@end example
+
+@noindent
+defines a variable named @code{objects}.  Whitespace around the variable
+name and immediately after the @samp{=} is ignored.
+
+Variables defined with @samp{=} are @dfn{recursively expanded} variables.
+Variables defined with @samp{:=} are @dfn{simply expanded} variables; these
+definitions can contain variable references which will be expanded before
+the definition is made.  @xref{Flavors, ,The Two Flavors of Variables}.
+
+The variable name may contain function and variable references, which
+are expanded when the line is read to find the actual variable name to use.
+
+There is no limit on the length of the value of a variable except the
+amount of swapping space on the computer.  When a variable definition is
+long, it is a good idea to break it into several lines by inserting
+backslash-newline at convenient places in the definition.  This will not
+affect the functioning of @code{make}, but it will make the makefile easier
+to read.
+
+Most variable names are considered to have the empty string as a value if
+you have never set them.  Several variables have built-in initial values
+that are not empty, but you can set them in the usual ways
+(@pxref{Implicit Variables, ,Variables Used by Implicit Rules}).
+Several special variables are set
+automatically to a new value for each rule; these are called the
+@dfn{automatic} variables (@pxref{Automatic Variables}).
+
+If you'd like a variable to be set to a value only if it's not already
+set, then you can use the shorthand operator @samp{?=} instead of
+@samp{=}.  These two settings of the variable @samp{FOO} are identical
+(@pxref{Origin Function, ,The @code{origin} Function}):
+
+@example

+@section Appending More Text to Variables
+@cindex +=
+@cindex appending to variables
+@cindex variables, appending to
+
+Often it is useful to add more text to the value of a variable already defined.
+You do this with a line containing @samp{+=}, like this:
+
+@example
+objects += another.o
+@end example
+
+@noindent
+This takes the value of the variable @code{objects}, and adds the text
+@samp{another.o} to it (preceded by a single space).  Thus:
+
+@example
+objects = main.o foo.o bar.o utils.o
+objects += another.o
+@end example
+
+@noindent
+sets @code{objects} to @samp{main.o foo.o bar.o utils.o another.o}.
+
+Using @samp{+=} is similar to:
+
+@example
+objects = main.o foo.o bar.o utils.o
+objects := $(objects) another.o
+@end example
+
+@noindent
+but differs in ways that become important when you use more complex values.
+
+When the variable in question has not been defined before, @samp{+=}
+acts just like normal @samp{=}: it defines a recursively-expanded
+variable.  However, when there @emph{is} a previous definition, exactly
+what @samp{+=} does depends on what flavor of variable you defined
+originally.  @xref{Flavors, ,The Two Flavors of Variables}, for an
+explanation of the two flavors of variables.
+
+When you add to a variable's value with @samp{+=}, @code{make} acts
+essentially as if you had included the extra text in the initial
+definition of the variable.  If you defined it first with @samp{:=},
+making it a simply-expanded variable, @samp{+=} adds to that
+simply-expanded definition, and expands the new text before appending it
+to the old value just as @samp{:=} does
+(@pxref{Setting, ,Setting Variables}, for a full explanation of @samp{:=}).
+In fact,
+
+@example
+variable := value
+variable += more
+@end example
+
+@noindent
+is exactly equivalent to:
+
+@noindent
+@example
+variable := value
+variable := $(variable) more
+@end example
+
+On the other hand, when you use @samp{+=} with a variable that you defined
+first to be recursively-expanded using plain @samp{=}, @code{make} does
+something a bit different.  Recall that when you define a
+recursively-expanded variable, @code{make} does not expand the value you set
+for variable and function references immediately.  Instead it stores the text
+verbatim, and saves these variable and function references to be expanded
+later, when you refer to the new variable (@pxref{Flavors, ,The Two Flavors
+of Variables}).  When you use @samp{+=} on a recursively-expanded variable,
+it is this unexpanded text to which @code{make} appends the new text you
+specify.
+
+@example
+@group
+variable = value
+variable += more
+@end group
+@end example
+
+@noindent
+is roughly equivalent to:
+
+@example
+@group
+temp = value
+variable = $(temp) more
+@end group
+@end example
+
+@noindent
+except that of course it never defines a variable called @code{temp}.
+The importance of this comes when the variable's old value contains
+variable references.  Take this common example:
+
+@example
+CFLAGS = $(includes) -O
+@dots{}
+CFLAGS += -pg # enable profiling
+@end example
+
+@noindent
+The first line defines the @code{CFLAGS} variable with a reference to another
+variable, @code{includes}.  (@code{CFLAGS} is used by the rules for C
+compilation; @pxref{Catalogue of Rules, ,Catalogue of Implicit Rules}.)
+Using @samp{=} for the definition makes @code{CFLAGS} a recursively-expanded
+variable, meaning @w{@samp{$(includes) -O}} is @emph{not} expanded when
+@code{make} processes the definition of @code{CFLAGS}.  Thus, @code{includes}
+need not be defined yet for its value to take effect.  It only has to be
+defined before any reference to @code{CFLAGS}.  If we tried to append to the
+value of @code{CFLAGS} without using @samp{+=}, we might do it like this:
+
+@example
+CFLAGS := $(CFLAGS) -pg # enable profiling
+@end example
+
+@noindent
+This is pretty close, but not quite what we want.  Using @samp{:=}
+redefines @code{CFLAGS} as a simply-expanded variable; this means
+@code{make} expands the text @w{@samp{$(CFLAGS) -pg}} before setting the
+variable.  If @code{includes} is not yet defined, we get @w{@samp{ -O
+-pg}}, and a later definition of @code{includes} will have no effect.
+Conversely, by using @samp{+=} we set @code{CFLAGS} to the
+@emph{unexpanded} value @w{@samp{$(includes) -O -pg}}.  Thus we preserve
+the reference to @code{includes}, so if that variable gets defined at
+any later point, a reference like @samp{$(CFLAGS)} still uses its
+value.

+@cindex overriding with @code{override}
+@cindex variables, overriding
+
+If a variable has been set with a command argument
+(@pxref{Overriding, ,Overriding Variables}),
+then ordinary assignments in the makefile are ignored.  If you want to set
+the variable in the makefile even though it was set with a command
+argument, you can use an @code{override} directive, which is a line that
+looks like this:@refill
+
+@example
+override @var{variable} = @var{value}
+@end example
+
+@noindent
+or
+
+@example
+override @var{variable} := @var{value}
+@end example
+
+To append more text to a variable defined on the command line, use:
+
+@example
+override @var{variable} += @var{more text}
+@end example
+
+@noindent
+@xref{Appending, ,Appending More Text to Variables}.
+
+The @code{override} directive was not invented for escalation in the war
+between makefiles and command arguments.  It was invented so you can alter
+and add to values that the user specifies with command arguments.
+
+For example, suppose you always want the @samp{-g} switch when you run the
+C compiler, but you would like to allow the user to specify the other
+switches with a command argument just as usual.  You could use this
+@code{override} directive:
+
+@example
+override CFLAGS += -g
+@end example
+
+You can also use @code{override} directives with @code{define} directives.
+This is done as you might expect:
+
+@example
+override define foo
+bar
+endef
+@end example
+
+@noindent

+@findex define
+@findex endef
+@cindex verbatim variable definition
+@cindex defining variables verbatim
+@cindex variables, defining verbatim
+
+Another way to set the value of a variable is to use the @code{define}
+directive.  This directive has an unusual syntax which allows newline
+characters to be included in the value, which is convenient for defining
+both canned sequences of commands
+(@pxref{Sequences, ,Defining Canned Command Sequences}), and also
+sections of makefile syntax to use with @code{eval} (@pxref{Eval Function}).
+
+The @code{define} directive is followed on the same line by the name of the
+variable and nothing more.  The value to give the variable appears on the
+following lines.  The end of the value is marked by a line containing just
+the word @code{endef}.  Aside from this difference in syntax, @code{define}
+works just like @samp{=}: it creates a recursively-expanded variable
+(@pxref{Flavors, ,The Two Flavors of Variables}).
+The variable name may contain function and variable references, which
+are expanded when the directive is read to find the actual variable name
+to use.
+
+You may nest @code{define} directives: @code{make} will keep track of
+nested directives and report an error if they are not all properly
+closed with @code{endef}.  Note that lines beginning with tab
+characters are considered part of a command script, so any
+@code{define} or @code{endef} strings appearing on such a line will
+not be considered @code{make} operators.
+
+@example
+define two-lines
+echo foo
+echo $(bar)
+endef
+@end example
+
+The value in an ordinary assignment cannot contain a newline; but the
+newlines that separate the lines of the value in a @code{define} become
+part of the variable's value (except for the final newline which precedes
+the @code{endef} and is not considered part of the value).@refill
+
+@need 800
+When used in a command script, the previous example is functionally
+equivalent to this:
+
+@example
+two-lines = echo foo; echo $(bar)
+@end example
+
+@noindent
+since two commands separated by semicolon behave much like two separate
+shell commands.  However, note that using two separate lines means
+@code{make} will invoke the shell twice, running an independent subshell
+for each line.  @xref{Execution, ,Command Execution}.
+
+If you want variable definitions made with @code{define} to take
+precedence over command-line variable definitions, you can use the
+@code{override} directive together with @code{define}:
+
+@example
+override define two-lines
+foo
+$(bar)
+endef
+@end example
+
+@noindent

+
+@node Environment, Target-specific, Defining, Using Variables
+@section Variables from the Environment
+
+@cindex variables, environment
+@cindex environment
+Variables in @code{make} can come from the environment in which
+@code{make} is run.  Every environment variable that @code{make} sees when
+it starts up is transformed into a @code{make} variable with the same name
+and value.  But an explicit assignment in the makefile, or with a command
+argument, overrides the environment.  (If the @samp{-e} flag is specified,
+then values from the environment override assignments in the makefile.
+@xref{Options Summary, ,Summary of Options}.
+But this is not recommended practice.)
+
+Thus, by setting the variable @code{CFLAGS} in your environment, you can
+cause all C compilations in most makefiles to use the compiler switches you
+prefer.  This is safe for variables with standard or conventional meanings
+because you know that no makefile will use them for other things.  (But
+this is not totally reliable; some makefiles set @code{CFLAGS} explicitly
+and therefore are not affected by the value in the environment.)
+
+When @code{make} is invoked recursively, variables defined in the
+outer invocation can be passed to inner invocations through the
+environment (@pxref{Recursion, ,Recursive Use of @code{make}}).  By
+default, only variables that came from the environment or the command
+line are passed to recursive invocations.  You can use the
+@code{export} directive to pass other variables.
+@xref{Variables/Recursion, , Communicating Variables to a
+Sub-@code{make}}, for full details.
+
+Other use of variables from the environment is not recommended.  It is not
+wise for makefiles to depend for their functioning on environment variables
+set up outside their control, since this would cause different users to get
+different results from the same makefile.  This is against the whole
+purpose of most makefiles.
+
+Such problems would be especially likely with the variable @code{SHELL},
+which is normally present in the environment to specify the user's choice
+of interactive shell.  It would be very undesirable for this choice to
+affect @code{make}.  So @code{make} ignores the environment value of

+usually not set.  @xref{Execution, ,Special handling of SHELL on
+MS-DOS}.)@refill

+
+Variable values in @code{make} are usually global; that is, they are the
+same regardless of where they are evaluated (unless they're reset, of
+course).  One exception to that is automatic variables
+(@pxref{Automatic Variables}).
+
+The other exception is @dfn{target-specific variable values}.  This
+feature allows you to define different values for the same variable,
+based on the target that @code{make} is currently building.  As with
+automatic variables, these values are only available within the context
+of a target's command script (and in other target-specific assignments).
+
+Set a target-specific variable value like this:
+
+@example
+@var{target} @dots{} : @var{variable-assignment}
+@end example
+
+@noindent
+or like this:
+
+@example
+@var{target} @dots{} : override @var{variable-assignment}
+@end example
+
+@noindent
+or like this:
+
+@example
+@var{target} @dots{} : export @var{variable-assignment}
+@end example
+
+Multiple @var{target} values create a target-specific variable value for
+each member of the target list individually.
+
+The @var{variable-assignment} can be any valid form of assignment;
+recursive (@samp{=}), static (@samp{:=}), appending (@samp{+=}), or
+conditional (@samp{?=}).  All variables that appear within the
+@var{variable-assignment} are evaluated within the context of the
+target: thus, any previously-defined target-specific variable values
+will be in effect.  Note that this variable is actually distinct from
+any ``global'' value: the two variables do not have to have the same
+flavor (recursive vs. static).
+
+Target-specific variables have the same priority as any other makefile
+variable.  Variables provided on the command-line (and in the
+environment if the @samp{-e} option is in force) will take precedence.
+Specifying the @code{override} directive will allow the target-specific
+variable value to be preferred.
+
+There is one more special feature of target-specific variables: when you
+define a target-specific variable, that variable value is also in effect
+for all prerequisites of this target (unless those prerequisites override
+it with their own target-specific variable value).  So, for example, a
+statement like this:
+
+@example
+prog : CFLAGS = -g
+prog : prog.o foo.o bar.o
+@end example
+
+@noindent
+will set @code{CFLAGS} to @samp{-g} in the command script for
+@file{prog}, but it will also set @code{CFLAGS} to @samp{-g} in the
+command scripts that create @file{prog.o}, @file{foo.o}, and
+@file{bar.o}, and any command scripts which create their prerequisites.

+In addition to target-specific variable values
+(@pxref{Target-specific, ,Target-specific Variable Values}), GNU
+@code{make} supports pattern-specific variable values.  In this form,
+the variable is defined for any target that matches the pattern
+specified.  If a target matches more than one pattern, all the
+matching pattern-specific variables are interpreted in the order in
+which they were defined in the makefile, and collected together into
+one set.  Variables defined in this way are searched after any
+target-specific variables defined explicitly for that target, and
+before target-specific variables defined for the parent target.

+Set a pattern-specific variable value like this:

+A @dfn{conditional} causes part of a makefile to be obeyed or ignored
+depending on the values of variables.  Conditionals can compare the
+value of one variable to another, or the value of a variable to

+@section Example of a Conditional
+
+The following example of a conditional tells @code{make} to use one set
+of libraries if the @code{CC} variable is @samp{gcc}, and a different
+set of libraries otherwise.  It works by controlling which of two
+command lines will be used as the command for a rule.  The result is
+that @samp{CC=gcc} as an argument to @code{make} changes not only which
+compiler is used but also which libraries are linked.
+
+@example
+libs_for_gcc = -lgnu
+normal_libs =
+
+foo: $(objects)
+ifeq ($(CC),gcc)
+        $(CC) -o foo $(objects) $(libs_for_gcc)
+else
+        $(CC) -o foo $(objects) $(normal_libs)
+endif
+@end example
+
+This conditional uses three directives: one @code{ifeq}, one @code{else}
+and one @code{endif}.
+
+The @code{ifeq} directive begins the conditional, and specifies the
+condition.  It contains two arguments, separated by a comma and surrounded
+by parentheses.  Variable substitution is performed on both arguments and
+then they are compared.  The lines of the makefile following the
+@code{ifeq} are obeyed if the two arguments match; otherwise they are
+ignored.
+
+The @code{else} directive causes the following lines to be obeyed if the
+previous conditional failed.  In the example above, this means that the
+second alternative linking command is used whenever the first alternative
+is not used.  It is optional to have an @code{else} in a conditional.
+
+The @code{endif} directive ends the conditional.  Every conditional must
+end with an @code{endif}.  Unconditional makefile text follows.
+
+As this example illustrates, conditionals work at the textual level:
+the lines of the conditional are treated as part of the makefile, or
+ignored, according to the condition.  This is why the larger syntactic
+units of the makefile, such as rules, may cross the beginning or the
+end of the conditional.
+
+When the variable @code{CC} has the value @samp{gcc}, the above example has
+this effect:
+
+@example
+foo: $(objects)
+        $(CC) -o foo $(objects) $(libs_for_gcc)
+@end example
+
+@noindent
+When the variable @code{CC} has any other value, the effect is this:
+
+@example
+foo: $(objects)
+        $(CC) -o foo $(objects) $(normal_libs)
+@end example
+
+Equivalent results can be obtained in another way by conditionalizing a
+variable assignment and then using the variable unconditionally:
+
+@example
+libs_for_gcc = -lgnu
+normal_libs =
+
+ifeq ($(CC),gcc)
+  libs=$(libs_for_gcc)
+else
+  libs=$(normal_libs)
+endif
+
+foo: $(objects)
+        $(CC) -o foo $(objects) $(libs)
+@end example

+
+The syntax of a simple conditional with no @code{else} is as follows:
+
+@example
+@var{conditional-directive}
+@var{text-if-true}
+endif
+@end example
+
+@noindent
+The @var{text-if-true} may be any lines of text, to be considered as part
+of the makefile if the condition is true.  If the condition is false, no
+text is used instead.
+
+The syntax of a complex conditional is as follows:
+
+@example
+@var{conditional-directive}
+@var{text-if-true}
+else
+@var{text-if-false}
+endif
+@end example
+
+@noindent
+If the condition is true, @var{text-if-true} is used; otherwise,
+@var{text-if-false} is used instead.  The @var{text-if-false} can be any
+number of lines of text.
+
+The syntax of the @var{conditional-directive} is the same whether the
+conditional is simple or complex.  There are four different directives that
+test different conditions.  Here is a table of them:
+
+@table @code
+@item ifeq (@var{arg1}, @var{arg2})
+@itemx ifeq '@var{arg1}' '@var{arg2}'
+@itemx ifeq "@var{arg1}" "@var{arg2}"
+@itemx ifeq "@var{arg1}" '@var{arg2}'
+@itemx ifeq '@var{arg1}' "@var{arg2}"
+Expand all variable references in @var{arg1} and @var{arg2} and
+compare them.  If they are identical, the @var{text-if-true} is
+effective; otherwise, the @var{text-if-false}, if any, is effective.
+
+Often you want to test if a variable has a non-empty value.  When the
+value results from complex expansions of variables and functions,
+expansions you would consider empty may actually contain whitespace
+characters and thus are not seen as empty.  However, you can use the
+@code{strip} function (@pxref{Text Functions}) to avoid interpreting
+whitespace as a non-empty value.  For example:
+
+@example
+@group
+ifeq ($(strip $(foo)),)
+@var{text-if-empty}
+endif
+@end group
+@end example
+
+@noindent
+will evaluate @var{text-if-empty} even if the expansion of
+@code{$(foo)} contains whitespace characters.
+
+@item ifneq (@var{arg1}, @var{arg2})
+@itemx ifneq '@var{arg1}' '@var{arg2}'
+@itemx ifneq "@var{arg1}" "@var{arg2}"
+@itemx ifneq "@var{arg1}" '@var{arg2}'
+@itemx ifneq '@var{arg1}' "@var{arg2}"
+Expand all variable references in @var{arg1} and @var{arg2} and
+compare them.  If they are different, the @var{text-if-true} is
+effective; otherwise, the @var{text-if-false}, if any, is effective.
+
+@item ifdef @var{variable-name}
+If the variable @var{variable-name} has a non-empty value, the
+@var{text-if-true} is effective; otherwise, the @var{text-if-false},
+if any, is effective.  Variables that have never been defined have an
+empty value.  The variable @var{variable-name} is itself expanded, so
+it could be a variable or function that expands to the name of a
+variable.
+
+Note that @code{ifdef} only tests whether a variable has a value.  It
+does not expand the variable to see if that value is nonempty.
+Consequently, tests using @code{ifdef} return true for all definitions
+except those like @code{foo =}.  To test for an empty value, use
+@w{@code{ifeq ($(foo),)}}.  For example,
+
+@example
+bar =
+foo = $(bar)
+ifdef foo
+frobozz = yes
+else
+frobozz = no
+endif
+@end example
+
+@noindent
+sets @samp{frobozz} to @samp{yes}, while:
+
+@example
+foo =
+ifdef foo
+frobozz = yes
+else
+frobozz = no
+endif
+@end example
+
+@noindent
+sets @samp{frobozz} to @samp{no}.
+
+@item ifndef @var{variable-name}
+If the variable @var{variable-name} has an empty value, the
+@var{text-if-true} is effective; otherwise, the @var{text-if-false},
+if any, is effective.
+@end table
+
+Extra spaces are allowed and ignored at the beginning of the conditional
+directive line, but a tab is not allowed.  (If the line begins with a tab,
+it will be considered a command for a rule.)  Aside from this, extra spaces
+or tabs may be inserted with no effect anywhere except within the directive
+name or within an argument.  A comment starting with @samp{#} may appear at
+the end of the line.
+
+The other two directives that play a part in a conditional are @code{else}
+and @code{endif}.  Each of these directives is written as one word, with no
+arguments.  Extra spaces are allowed and ignored at the beginning of the
+line, and spaces or tabs at the end.  A comment starting with @samp{#} may
+appear at the end of the line.
+
+Conditionals affect which lines of the makefile @code{make} uses.  If
+the condition is true, @code{make} reads the lines of the
+@var{text-if-true} as part of the makefile; if the condition is false,
+@code{make} ignores those lines completely.  It follows that syntactic
+units of the makefile, such as rules, may safely be split across the
+beginning or the end of the conditional.@refill
+
+@code{make} evaluates conditionals when it reads a makefile.
+Consequently, you cannot use automatic variables in the tests of
+conditionals because they are not defined until commands are run
+(@pxref{Automatic Variables}).
+
+To prevent intolerable confusion, it is not permitted to start a
+conditional in one makefile and end it in another.  However, you may
+write an @code{include} directive within a conditional, provided you do
+not attempt to terminate the conditional inside the included file.
+
+@node Testing Flags,  , Conditional Syntax, Conditionals
+@section Conditionals that Test Flags
+
+You can write a conditional that tests @code{make} command flags such as
+@samp{-t} by using the variable @code{MAKEFLAGS} together with the
+@code{findstring} function
+(@pxref{Text Functions, , Functions for String Substitution and Analysis}).
+This is useful when @code{touch} is not enough to make a file appear up
+to date.
+
+The @code{findstring} function determines whether one string appears as a
+substring of another.  If you want to test for the @samp{-t} flag,
+use @samp{t} as the first string and the value of @code{MAKEFLAGS} as
+the other.
+
+For example, here is how to arrange to use @samp{ranlib -t} to finish
+marking an archive file up to date:
+
+@example
+archive.a: @dots{}
+ifneq (,$(findstring t,$(MAKEFLAGS)))
+        +touch archive.a
+        +ranlib -t archive.a
+else
+        ranlib archive.a
+endif
+@end example
+
+@noindent
+The @samp{+} prefix marks those command lines as ``recursive'' so
+that they will be executed despite use of the @samp{-t} flag.

+
+A function call resembles a variable reference.  It looks like this:
+
+@example
+$(@var{function} @var{arguments})
+@end example
+
+@noindent
+or like this:
+
+@example
+$@{@var{function} @var{arguments}@}
+@end example
+
+Here @var{function} is a function name; one of a short list of names
+that are part of @code{make}.  You can also essentially create your own
+functions by using the @code{call} builtin function.
+
+The @var{arguments} are the arguments of the function.  They are
+separated from the function name by one or more spaces or tabs, and if
+there is more than one argument, then they are separated by commas.
+Such whitespace and commas are not part of an argument's value.  The
+delimiters which you use to surround the function call, whether
+parentheses or braces, can appear in an argument only in matching pairs;
+the other kind of delimiters may appear singly.  If the arguments
+themselves contain other function calls or variable references, it is
+wisest to use the same kind of delimiters for all the references; write
+@w{@samp{$(subst a,b,$(x))}}, not @w{@samp{$(subst a,b,$@{x@})}}.  This
+is because it is clearer, and because only one type of delimiter is
+matched to find the end of the reference.
+
+The text written for each argument is processed by substitution of
+variables and function calls to produce the argument value, which
+is the text on which the function acts.  The substitution is done in the
+order in which the arguments appear.
+
+Commas and unmatched parentheses or braces cannot appear in the text of an
+argument as written; leading spaces cannot appear in the text of the first
+argument as written.  These characters can be put into the argument value
+by variable substitution.  First define variables @code{comma} and
+@code{space} whose values are isolated comma and space characters, then
+substitute these variables where such characters are wanted, like this:
+
+@example
+@group
+comma:= ,
+empty:=
+space:= $(empty) $(empty)
+foo:= a b c
+bar:= $(subst $(space),$(comma),$(foo))
+# @r{bar is now `a,b,c'.}
+@end group
+@end example
+
+@noindent
+Here the @code{subst} function replaces each space with a comma, through
+the value of @code{foo}, and substitutes the result.

+@table @code
+@item $(subst @var{from},@var{to},@var{text})

+Performs a textual replacement on the text @var{text}: each occurrence
+of @var{from} is replaced by @var{to}.  The result is substituted for
+the function call.  For example,
+
+@example
+$(subst ee,EE,feet on the street)
+@end example
+
+substitutes the string @samp{fEEt on the strEEt}.
+
+@item $(patsubst @var{pattern},@var{replacement},@var{text})
+@findex patsubst
+Finds whitespace-separated words in @var{text} that match
+@var{pattern} and replaces them with @var{replacement}.  Here
+@var{pattern} may contain a @samp{%} which acts as a wildcard,
+matching any number of any characters within a word.  If
+@var{replacement} also contains a @samp{%}, the @samp{%} is replaced
+by the text that matched the @samp{%} in @var{pattern}.  Only the first
+@samp{%} in the @var{pattern} and @var{replacement} is treated this
+way; any subsequent @samp{%} is unchanged.@refill

+@samp{%} characters in @code{patsubst} function invocations can be
+quoted with preceding backslashes (@samp{\}).  Backslashes that would
+otherwise quote @samp{%} characters can be quoted with more backslashes.
+Backslashes that quote @samp{%} characters or other backslashes are
+removed from the pattern before it is compared file names or has a stem
+substituted into it.  Backslashes that are not in danger of quoting
+@samp{%} characters go unmolested.  For example, the pattern
+@file{the\%weird\\%pattern\\} has @samp{the%weird\} preceding the
+operative @samp{%} character, and @samp{pattern\\} following it.  The
+final two backslashes are left alone because they cannot affect any
+@samp{%} character.@refill
+
+Whitespace between words is folded into single space characters;
+leading and trailing whitespace is discarded.
+
+For example,
+
+@example
+$(patsubst %.c,%.o,x.c.c bar.c)
+@end example
+
+@noindent
+produces the value @samp{x.c.o bar.o}.
+
+Substitution references (@pxref{Substitution Refs, ,Substitution

+function:
+
+@example
+$(@var{var}:@var{pattern}=@var{replacement})
+@end example
+
+@noindent
+is equivalent to
+
+@example
+$(patsubst @var{pattern},@var{replacement},$(@var{var}))
+@end example
+
+The second shorthand simplifies one of the most common uses of
+@code{patsubst}: replacing the suffix at the end of file names.
+
+@example
+$(@var{var}:@var{suffix}=@var{replacement})
+@end example
+
+@noindent
+is equivalent to
+
+@example
+$(patsubst %@var{suffix},%@var{replacement},$(@var{var}))
+@end example
+
+@noindent
+For example, you might have a list of object files:
+
+@example
+objects = foo.o bar.o baz.o
+@end example
+
+@noindent
+To get the list of corresponding source files, you could simply write:
+
+@example
+$(objects:.o=.c)
+@end example
+

+instead of using the general form:

+@example

+Removes leading and trailing whitespace from @var{string} and replaces

+single space.  Thus, @samp{$(strip a b  c )} results in @w{@samp{a b c}}.
+
+The function @code{strip} can be very useful when used in conjunction
+with conditionals.  When comparing something with the empty string
+@samp{} using @code{ifeq} or @code{ifneq}, you usually want a string of

+(@pxref{General Search, , @code{VPATH} Search Path for All Prerequisites}).

+
+The value of @code{VPATH} is a list of directories separated by colons,

+@example
+$(subst :, ,$(VPATH))

+This produces @samp{src ../headers}.  Then @code{patsubst} is used to turn

+compiler, like this:
+
+@example
+override CFLAGS += $(patsubst %,-I%,$(subst :, ,$(VPATH)))
+@end example
+
+@noindent
+The effect is to append the text @samp{-Isrc -I../headers} to the

+@cindex functions, for file names
+@cindex file name functions
+
+Several of the built-in expansion functions relate specifically to
+taking apart file names or lists of file names.
+
+Each of the following functions performs a specific transformation on a
+file name.  The argument of the function is regarded as a series of file
+names, separated by whitespace.  (Leading and trailing whitespace is
+ignored.)  Each file name in the series is transformed in the same way and
+the results are concatenated with single spaces between them.
+
+@table @code
+@item $(dir @var{names}@dots{})
+@findex dir
+@cindex directory part
+@cindex file name, directory part
+Extracts the directory-part of each file name in @var{names}.  The
+directory-part of the file name is everything up through (and
+including) the last slash in it.  If the file name contains no slash,
+the directory part is the string @samp{./}.  For example,
+
+@example
+$(dir src/foo.c hacks)
+@end example
+
+@noindent
+produces the result @samp{src/ ./}.
+
+@item $(notdir @var{names}@dots{})
+@findex notdir
+@cindex file name, nondirectory part
+@cindex nondirectory part
+Extracts all but the directory-part of each file name in @var{names}.
+If the file name contains no slash, it is left unchanged.  Otherwise,
+everything through the last slash is removed from it.
+
+A file name that ends with a slash becomes an empty string.  This is
+unfortunate, because it means that the result does not always have the
+same number of whitespace-separated file names as the argument had;
+but we do not see any other valid alternative.
+
+For example,
+
+@example
+$(notdir src/foo.c hacks)
+@end example

+
+@item $(suffix @var{names}@dots{})
+@findex suffix
+@cindex suffix, function to find
+@cindex file name suffix
+Extracts the suffix of each file name in @var{names}.  If the file name
+contains a period, the suffix is everything starting with the last
+period.  Otherwise, the suffix is the empty string.  This frequently
+means that the result will be empty when @var{names} is not, and if
+@var{names} contains multiple file names, the result may contain fewer
+file names.
+
+For example,
+
+@example
+$(suffix src/foo.c src-1.0/bar.c hacks)

+For example,

+two second words form the second word of the result, and so on.  So the
+@var{n}th word of the result comes from the @var{n}th word of each
+argument.  If one argument has more words that the other, the extra
+words are copied unchanged into the result.
+
+For example, @samp{$(join a b,.c .o)} produces @samp{a.c b.o}.
+
+Whitespace between the words in the lists is not preserved; it is

+@section The @code{foreach} Function
+@findex foreach
+@cindex words, iterating over
+
+The @code{foreach} function is very different from other functions.  It
+causes one piece of text to be used repeatedly, each time with a different
+substitution performed on it.  It resembles the @code{for} command in the
+shell @code{sh} and the @code{foreach} command in the C-shell @code{csh}.
+
+The syntax of the @code{foreach} function is:
+
+@example
+$(foreach @var{var},@var{list},@var{text})
+@end example
+
+@noindent
+The first two arguments, @var{var} and @var{list}, are expanded before
+anything else is done; note that the last argument, @var{text}, is
+@strong{not} expanded at the same time.  Then for each word of the expanded
+value of @var{list}, the variable named by the expanded value of @var{var}
+is set to that word, and @var{text} is expanded.  Presumably @var{text}
+contains references to that variable, so its expansion will be different
+each time.
+
+The result is that @var{text} is expanded as many times as there are
+whitespace-separated words in @var{list}.  The multiple expansions of
+@var{text} are concatenated, with spaces between them, to make the result
+of @code{foreach}.
+
+This simple example sets the variable @samp{files} to the list of all files
+in the directories in the list @samp{dirs}:
+
+@example
+dirs := a b c d
+files := $(foreach dir,$(dirs),$(wildcard $(dir)/*))
+@end example
+
+Here @var{text} is @samp{$(wildcard $(dir)/*)}.  The first repetition
+finds the value @samp{a} for @code{dir}, so it produces the same result
+as @samp{$(wildcard a/*)}; the second repetition produces the result
+of @samp{$(wildcard b/*)}; and the third, that of @samp{$(wildcard c/*)}.
+
+This example has the same result (except for setting @samp{dirs}) as
+the following example:
+
+@example
+files := $(wildcard a/* b/* c/* d/*)
+@end example
+
+When @var{text} is complicated, you can improve readability by giving it
+a name, with an additional variable:
+
+@example
+find_files = $(wildcard $(dir)/*)
+dirs := a b c d
+files := $(foreach dir,$(dirs),$(find_files))
+@end example
+
+@noindent
+Here we use the variable @code{find_files} this way.  We use plain @samp{=}
+to define a recursively-expanding variable, so that its value contains an
+actual function call to be reexpanded under the control of @code{foreach};
+a simply-expanded variable would not do, since @code{wildcard} would be
+called only once at the time of defining @code{find_files}.
+
+The @code{foreach} function has no permanent effect on the variable
+@var{var}; its value and flavor after the @code{foreach} function call are
+the same as they were beforehand.  The other values which are taken from
+@var{list} are in effect only temporarily, during the execution of
+@code{foreach}.  The variable @var{var} is a simply-expanded variable
+during the execution of @code{foreach}.  If @var{var} was undefined
+before the @code{foreach} function call, it is undefined after the call.
+@xref{Flavors, ,The Two Flavors of Variables}.@refill
+
+You must take care when using complex variable expressions that result in
+variable names because many strange things are valid variable names, but
+are probably not what you intended.  For example,
+
+@smallexample
+files := $(foreach Esta escrito en espanol!,b c ch,$(find_files))
+@end smallexample
+
+@noindent
+might be useful if the value of @code{find_files} references the variable
+whose name is @samp{Esta escrito en espanol!} (es un nombre bastante largo,
+no?), but it is more likely to be a mistake.
+
+@node If Function, Call Function, Foreach Function, Functions
+@section The @code{if} Function
+@findex if
+@cindex conditional expansion
+
+The @code{if} function provides support for conditional expansion in a
+functional context (as opposed to the GNU @code{make} makefile
+conditionals such as @code{ifeq} (@pxref{Conditional Syntax, ,Syntax of
+Conditionals}).
+
+An @code{if} function call can contain either two or three arguments:
+
+@example
+$(if @var{condition},@var{then-part}[,@var{else-part}])
+@end example
+
+The first argument, @var{condition}, first has all preceding and
+trailing whitespace stripped, then is expanded.  If it expands to any
+non-empty string, then the condition is considered to be true.  If it
+expands to an empty string, the condition is considered to be false.
+
+If the condition is true then the second argument, @var{then-part}, is
+evaluated and this is used as the result of the evaluation of the entire
+@code{if} function.
+
+If the condition is false then the third argument, @var{else-part}, is
+evaluated and this is the result of the @code{if} function.  If there is
+no third argument, the @code{if} function evaluates to nothing (the
+empty string).
+
+Note that only one of the @var{then-part} or the @var{else-part} will be
+evaluated, never both.  Thus, either can contain side-effects (such as
+@code{shell} function calls, etc.)
+
+@node Call Function, Value Function, If Function, Functions
+@section The @code{call} Function
+@findex call
+@cindex functions, user defined
+@cindex user defined functions
+
+The @code{call} function is unique in that it can be used to create new
+parameterized functions.  You can write a complex expression as the
+value of a variable, then use @code{call} to expand it with different
+values.
+
+The syntax of the @code{call} function is:
+
+@example
+$(call @var{variable},@var{param},@var{param},@dots{})
+@end example
+
+When @code{make} expands this function, it assigns each @var{param} to
+temporary variables @code{$(1)}, @code{$(2)}, etc.  The variable
+@code{$(0)} will contain @var{variable}.  There is no maximum number of
+parameter arguments.  There is no minimum, either, but it doesn't make
+sense to use @code{call} with no parameters.
+
+Then @var{variable} is expanded as a @code{make} variable in the context
+of these temporary assignments.  Thus, any reference to @code{$(1)} in
+the value of @var{variable} will resolve to the first @var{param} in the
+invocation of @code{call}.
+
+Note that @var{variable} is the @emph{name} of a variable, not a
+@emph{reference} to that variable.  Therefore you would not normally use
+a @samp{$} or parentheses when writing it.  (You can, however, use a
+variable reference in the name if you want the name not to be a
+constant.)
+
+If @var{variable} is the name of a builtin function, the builtin function
+is always invoked (even if a @code{make} variable by that name also
+exists).
+
+The @code{call} function expands the @var{param} arguments before
+assigning them to temporary variables.  This means that @var{variable}
+values containing references to builtin functions that have special
+expansion rules, like @code{foreach} or @code{if}, may not work as you
+expect.
+
+Some examples may make this clearer.
+
+This macro simply reverses its arguments:
+
+@smallexample
+reverse = $(2) $(1)
+
+foo = $(call reverse,a,b)
+@end smallexample
+
+@noindent
+Here @var{foo} will contain @samp{b a}.
+
+This one is slightly more interesting: it defines a macro to search for
+the first instance of a program in @code{PATH}:
+
+@smallexample
+pathsearch = $(firstword $(wildcard $(addsuffix /$(1),$(subst :, ,$(PATH)))))
+
+LS := $(call pathsearch,ls)
+@end smallexample
+
+@noindent
+Now the variable LS contains @code{/bin/ls} or similar.
+
+The @code{call} function can be nested.  Each recursive invocation gets
+its own local values for @code{$(1)}, etc. that mask the values of
+higher-level @code{call}.  For example, here is an implementation of a
+@dfn{map} function:
+
+@smallexample
+map = $(foreach a,$(2),$(call $(1),$(a)))
+@end smallexample
+
+Now you can @var{map} a function that normally takes only one argument,
+such as @code{origin}, to multiple values in one step:
+
+@smallexample
+o = $(call map,origin,o map MAKE)
+@end smallexample
+
+and end up with @var{o} containing something like @samp{file file default}.
+
+A final caution: be careful when adding whitespace to the arguments to
+@code{call}.  As with other functions, any whitespace contained in the
+second and subsequent arguments is kept; this can cause strange
+effects.  It's generally safest to remove all extraneous whitespace when
+providing parameters to @code{call}.

+@section The @code{value} Function
+@findex value
+@cindex variables, unexpanded value
+
+The @code{value} function provides a way for you to use the value of a
+variable @emph{without} having it expanded.  Please note that this
+does not undo expansions which have already occurred; for example if
+you create a simply expanded variable its value is expanded during the
+definition; in that case the @code{value} function will return the
+same result as using the variable directly.
+
+The syntax of the @code{value} function is:
+
+@example
+$(value @var{variable})
+@end example
+
+Note that @var{variable} is the @emph{name} of a variable; not a
+@emph{reference} to that variable.  Therefore you would not normally
+use a @samp{$} or parentheses when writing it.  (You can, however, use
+a variable reference in the name if you want the name not to be a
+constant.)
+
+The result of this function is a string containing the value of
+@var{variable}, without any expansion occurring.  For example, in this
+makefile:
+
+@example
+@group
+FOO = $PATH
+

+        @@echo $(FOO)
+        @@echo $(value FOO)
+@end group
+@end example
+
+@noindent
+The first output line would be @code{ATH}, since the ``$P'' would be
+expanded as a @code{make} variable, while the second output line would
+be the current value of your @code{$PATH} environment variable, since
+the @code{value} function avoided the expansion.
+
+The @code{value} function is most often used in conjunction with the
+@code{eval} function (@pxref{Eval Function}).

+@section The @code{eval} Function
+@findex eval
+@cindex evaluating makefile syntax
+@cindex makefile syntax, evaluating
+
+The @code{eval} function is very special: it allows you to define new
+makefile constructs that are not constant; which are the result of
+evaluating other variables and functions.  The argument to the
+@code{eval} function is expanded, then the results of that expansion
+are parsed as makefile syntax.  The expanded results can define new
+@code{make} variables, targets, implicit or explicit rules, etc.
+
+The result of the @code{eval} function is always the empty string;
+thus, it can be placed virtually anywhere in a makefile without
+causing syntax errors.
+
+It's important to realize that the @code{eval} argument is expanded
+@emph{twice}; first by the @code{eval} function, then the results of
+that expansion are expanded again when they are parsed as makefile
+syntax.  This means you may need to provide extra levels of escaping
+for ``$'' characters when using @code{eval}.  The @code{value}
+function (@pxref{Value Function}) can sometimes be useful in these
+situations, to circumvent unwanted expansions.
+
+Here is an example of how @code{eval} can be used; this example
+combines a number of concepts and other functions.  Although it might
+seem overly complex to use @code{eval} in this example, rather than
+just writing out the rules, consider two things: first, the template
+definition (in @code{PROGRAM_template}) could need to be much more
+complex than it is here; and second, you might put the complex,
+``generic'' part of this example into another makefile, then include
+it in all the individual makefiles.  Now your individual makefiles are
+quite straightforward.

+The @code{shell} function is unlike any other function except the

+(@pxref{Wildcard Function, ,The Function @code{wildcard}}) in that it
+communicates with the world outside of @code{make}.
+
+The @code{shell} function performs the same function that backquotes
+(@samp{`}) perform in most shells: it does @dfn{command expansion}.  This
+means that it takes an argument that is a shell command and returns the
+output of the command.  The only processing @code{make} does on the result,
+before substituting it into the surrounding text, is to convert each
+newline or carriage-return / newline pair to a single space.  It also
+removes the trailing (carriage-return and) newline, if it's the last
+thing in the result.@refill
+
+The commands run by calls to the @code{shell} function are run when the
+function calls are expanded (@pxref{Reading Makefiles, , How
+@code{make} Reads a Makefile}).  Because this function involves
+spawning a new shell, you should carefully consider the performance
+implications of using the @code{shell} function within recursively
+expanded variables vs. simply expanded variables (@pxref{Flavors, ,The
+Two Flavors of Variables}).
+
+Here are some examples of the use of the @code{shell} function:
+
+@example
+contents := $(shell cat foo)

+sets @code{contents} to the contents of the file @file{foo}, with a space
+(rather than a newline) separating each line.
+
+@example
+files := $(shell echo *.c)
+@end example
+
+@noindent

+@chapter How to Run @code{make}
+
+A makefile that says how to recompile a program can be used in more
+than one way.  The simplest use is to recompile every file that is out
+of date.  Usually, makefiles are written so that if you run
+@code{make} with no arguments, it does just that.
+
+But you might want to update only some of the files; you might want to use
+a different compiler or different compiler options; you might want just to
+find out which files are out of date without changing them.
+
+By giving arguments when you run @code{make}, you can do any of these
+things and many others.
+
+The exit status of @code{make} is always one of three values:
+@table @code
+@item 0
+The exit status is zero if @code{make} is successful.
+@item 2
+The exit status is two if @code{make} encounters any errors.
+It will print messages describing the particular errors.
+@item 1
+The exit status is one if you use the @samp{-q} flag and @code{make}
+determines that some target is not already up to date.

+@section Arguments to Specify the Makefile
+@cindex @code{--file}
+@cindex @code{--makefile}
+@cindex @code{-f}
+
+The way to specify the name of the makefile is with the @samp{-f} or
+@samp{--file} option (@samp{--makefile} also works).  For example,
+@samp{-f altmake} says to use the file @file{altmake} as the makefile.
+
+If you use the @samp{-f} flag several times and follow each @samp{-f}
+with an argument, all the specified files are used jointly as
+makefiles.
+
+If you do not use the @samp{-f} or @samp{--file} flag, the default is
+to try @file{GNUmakefile}, @file{makefile}, and @file{Makefile}, in
+that order, and use the first of these three which exists or can be made
+(@pxref{Makefiles, ,Writing Makefiles}).@refill
+
+@node Goals, Instead of Execution, Makefile Arguments, Running
+@section Arguments to Specify the Goals
+@cindex goal, how to specify
+
+The @dfn{goals} are the targets that @code{make} should strive ultimately
+to update.  Other targets are updated as well if they appear as
+prerequisites of goals, or prerequisites of prerequisites of goals, etc.
+
+By default, the goal is the first target in the makefile (not counting
+targets that start with a period).  Therefore, makefiles are usually
+written so that the first target is for compiling the entire program or
+programs they describe.  If the first rule in the makefile has several
+targets, only the first target in the rule becomes the default goal, not
+the whole list.
+
+You can specify a different goal or goals with arguments to @code{make}.
+Use the name of the goal as an argument.  If you specify several goals,
+@code{make} processes each of them in turn, in the order you name them.
+
+Any target in the makefile may be specified as a goal (unless it
+starts with @samp{-} or contains an @samp{=}, in which case it will be
+parsed as a switch or variable definition, respectively).  Even
+targets not in the makefile may be specified, if @code{make} can find
+implicit rules that say how to make them.
+
+@cindex @code{MAKECMDGOALS}
+@vindex MAKECMDGOALS
+@code{Make} will set the special variable @code{MAKECMDGOALS} to the
+list of goals you specified on the command line.  If no goals were given
+on the command line, this variable is empty.  Note that this variable
+should be used only in special circumstances.
+
+An example of appropriate use is to avoid including @file{.d} files
+during @code{clean} rules (@pxref{Automatic Prerequisites}), so
+@code{make} won't create them only to immediately remove them
+again:@refill
+
+@example
+@group
+sources = foo.c bar.c
+
+ifneq ($(MAKECMDGOALS),clean)
+include $(sources:.c=.d)
+endif
+@end group
+@end example
+
+One use of specifying a goal is if you want to compile only a part of
+the program, or only one of several programs.  Specify as a goal each
+file that you wish to remake.  For example, consider a directory containing
+several programs, with a makefile that starts like this:
+
+@example
+.PHONY: all
+all: size nm ld ar as
+@end example
+
+If you are working on the program @code{size}, you might want to say
+@w{@samp{make size}} so that only the files of that program are recompiled.
+
+Another use of specifying a goal is to make files that are not normally
+made.  For example, there may be a file of debugging output, or a
+version of the program that is compiled specially for testing, which has
+a rule in the makefile but is not a prerequisite of the default goal.
+
+Another use of specifying a goal is to run the commands associated with
+a phony target (@pxref{Phony Targets}) or empty target (@pxref{Empty
+Targets, ,Empty Target Files to Record Events}).  Many makefiles contain
+a phony target named @file{clean} which deletes everything except source
+files.  Naturally, this is done only if you request it explicitly with
+@w{@samp{make clean}}.  Following is a list of typical phony and empty
+target names.  @xref{Standard Targets}, for a detailed list of all the
+standard target names which GNU software packages use.
+
+@table @file
+@item all
+@cindex @code{all} @r{(standard target)}
+Make all the top-level targets the makefile knows about.
+
+@item clean
+@cindex @code{clean} @r{(standard target)}
+Delete all files that are normally created by running @code{make}.
+
+@item mostlyclean
+@cindex @code{mostlyclean} @r{(standard target)}
+Like @samp{clean}, but may refrain from deleting a few files that people
+normally don't want to recompile.  For example, the @samp{mostlyclean}
+target for GCC does not delete @file{libgcc.a}, because recompiling it
+is rarely necessary and takes a lot of time.
+
+@item distclean
+@cindex @code{distclean} @r{(standard target)}
+@itemx realclean
+@cindex @code{realclean} @r{(standard target)}
+@itemx clobber
+@cindex @code{clobber} @r{(standard target)}
+Any of these targets might be defined to delete @emph{more} files than
+@samp{clean} does.  For example, this would delete configuration files
+or links that you would normally create as preparation for compilation,
+even if the makefile itself cannot create these files.
+
+@item install
+@cindex @code{install} @r{(standard target)}
+Copy the executable file into a directory that users typically search
+for commands; copy any auxiliary files that the executable uses into
+the directories where it will look for them.
+
+@item print
+@cindex @code{print} @r{(standard target)}
+Print listings of the source files that have changed.
+

+
+@item dist

+be a tar file, or a shar file, or a compressed version of one of the

+header file requires recompilation of all dependent files, but you know
+that they do not need to be recompiled and you would rather not waste
+the time waiting for them to compile.
+
+If you anticipate the problem before changing the header file, you can
+use the @samp{-t} flag.  This flag tells @code{make} not to run the

+@section Overriding Variables
+@cindex overriding variables with arguments
+@cindex variables, overriding with arguments
+@cindex command line variables
+@cindex variables, command line
+
+An argument that contains @samp{=} specifies the value of a variable:
+@samp{@var{v}=@var{x}} sets the value of the variable @var{v} to @var{x}.
+If you specify a value in this way, all ordinary assignments of the same
+variable in the makefile are ignored; we say they have been
+@dfn{overridden} by the command line argument.
+
+The most common way to use this facility is to pass extra flags to
+compilers.  For example, in a properly written makefile, the variable
+@code{CFLAGS} is included in each command that runs the C compiler, so a
+file @file{foo.c} would be compiled something like this:
+
+@example
+cc -c $(CFLAGS) foo.c
+@end example
+
+Thus, whatever value you set for @code{CFLAGS} affects each compilation
+that occurs.  The makefile probably specifies the usual value for
+@code{CFLAGS}, like this:
+
+@example
+CFLAGS=-g
+@end example
+
+Each time you run @code{make}, you can override this value if you
+wish.  For example, if you say @samp{make CFLAGS='-g -O'}, each C
+compilation will be done with @samp{cc -c -g -O}.  (This also
+illustrates how you can use quoting in the shell to enclose spaces and
+other special characters in the value of a variable when you override
+it.)
+
+The variable @code{CFLAGS} is only one of many standard variables that
+exist just so that you can change them this way.  @xref{Implicit
+Variables, , Variables Used by Implicit Rules}, for a complete list.
+
+You can also program the makefile to look at additional variables of your
+own, giving the user the ability to control other aspects of how the
+makefile works by changing the variables.
+
+When you override a variable with a command argument, you can define either
+a recursively-expanded variable or a simply-expanded variable.  The
+examples shown above make a recursively-expanded variable; to make a
+simply-expanded variable, write @samp{:=} instead of @samp{=}.  But, unless
+you want to include a variable reference or function call in the
+@emph{value} that you specify, it makes no difference which kind of
+variable you create.
+
+There is one way that the makefile can change a variable that you have
+overridden.  This is to use the @code{override} directive, which is a line
+that looks like this: @samp{override @var{variable} = @var{value}}
+(@pxref{Override Directive, ,The @code{override} Directive}).

+@node Testing, Options Summary, Overriding, Running
+@section Testing the Compilation of a Program
+@cindex testing compilation
+@cindex compilation, testing
+
+Normally, when an error happens in executing a shell command, @code{make}
+gives up immediately, returning a nonzero status.  No further commands are
+executed for any target.  The error implies that the goal cannot be
+correctly remade, and @code{make} reports this as soon as it knows.
+
+When you are compiling a program that you have just changed, this is not
+what you want.  Instead, you would rather that @code{make} try compiling
+every file that can be tried, to show you as many compilation errors
+as possible.
+
+@cindex @code{-k}
+@cindex @code{--keep-going}
+On these occasions, you should use the @samp{-k} or
+@samp{--keep-going} flag.  This tells @code{make} to continue to
+consider the other prerequisites of the pending targets, remaking them
+if necessary, before it gives up and returns nonzero status.  For
+example, after an error in compiling one object file, @samp{make -k}
+will continue compiling other object files even though it already
+knows that linking them will be impossible.  In addition to continuing
+after failed shell commands, @samp{make -k} will continue as much as
+possible after discovering that it does not know how to make a target
+or prerequisite file.  This will always cause an error message, but
+without @samp{-k}, it is a fatal error (@pxref{Options Summary,
+,Summary of Options}).@refill
+
+The usual behavior of @code{make} assumes that your purpose is to get the
+goals up to date; once @code{make} learns that this is impossible, it might
+as well report the failure immediately.  The @samp{-k} flag says that the
+real purpose is to test as much as possible of the changes made in the
+program, perhaps to find several independent problems so that you can
+correct them all before the next attempt to compile.  This is why Emacs'
+@kbd{M-x compile} command passes the @samp{-k} flag by default.

+@cindex rule, implicit
+
+Certain standard ways of remaking target files are used very often.  For
+example, one customary way to make an object file is from a C source file
+using the C compiler, @code{cc}.
+
+@dfn{Implicit rules} tell @code{make} how to use customary techniques so
+that you do not have to specify them in detail when you want to use
+them.  For example, there is an implicit rule for C compilation.  File
+names determine which implicit rules are run.  For example, C
+compilation typically takes a @file{.c} file and makes a @file{.o} file.
+So @code{make} applies the implicit rule for C compilation when it sees
+this combination of file name endings.@refill
+
+A chain of implicit rules can apply in sequence; for example, @code{make}
+will remake a @file{.o} file from a @file{.y} file by way of a @file{.c} file.
+@iftex
+@xref{Chained Rules, ,Chains of Implicit Rules}.
+@end iftex
+
+The built-in implicit rules use several variables in their commands so
+that, by changing the values of the variables, you can change the way the
+implicit rule works.  For example, the variable @code{CFLAGS} controls the
+flags given to the C compiler by the implicit rule for C compilation.
+@iftex
+@xref{Implicit Variables, ,Variables Used by Implicit Rules}.
+@end iftex
+
+You can define your own implicit rules by writing @dfn{pattern rules}.
+@iftex
+@xref{Pattern Rules, ,Defining and Redefining Pattern Rules}.

+@dfn{Suffix rules} are a more limited way to define implicit rules.

+@section Using Implicit Rules
+@cindex implicit rule, how to use
+@cindex rule, implicit, how to use
+
+To allow @code{make} to find a customary method for updating a target file,
+all you have to do is refrain from specifying commands yourself.  Either
+write a rule with no command lines, or don't write a rule at all.  Then
+@code{make} will figure out which implicit rule to use based on which
+kind of source file exists or can be made.
+
+For example, suppose the makefile looks like this:
+
+@example
+foo : foo.o bar.o
+        cc -o foo foo.o bar.o $(CFLAGS) $(LDFLAGS)
+@end example
+
+@noindent
+Because you mention @file{foo.o} but do not give a rule for it, @code{make}
+will automatically look for an implicit rule that tells how to update it.
+This happens whether or not the file @file{foo.o} currently exists.
+
+If an implicit rule is found, it can supply both commands and one or
+more prerequisites (the source files).  You would want to write a rule
+for @file{foo.o} with no command lines if you need to specify additional
+prerequisites, such as header files, that the implicit rule cannot
+supply.
+
+Each implicit rule has a target pattern and prerequisite patterns.  There may
+be many implicit rules with the same target pattern.  For example, numerous
+rules make @samp{.o} files: one, from a @samp{.c} file with the C compiler;
+another, from a @samp{.p} file with the Pascal compiler; and so on.  The rule
+that actually applies is the one whose prerequisites exist or can be made.
+So, if you have a file @file{foo.c}, @code{make} will run the C compiler;
+otherwise, if you have a file @file{foo.p}, @code{make} will run the Pascal
+compiler; and so on.
+
+Of course, when you write the makefile, you know which implicit rule you
+want @code{make} to use, and you know it will choose that one because you
+know which possible prerequisite files are supposed to exist.
+@xref{Catalogue of Rules, ,Catalogue of Implicit Rules},
+for a catalogue of all the predefined implicit rules.
+
+Above, we said an implicit rule applies if the required prerequisites ``exist
+or can be made''.  A file ``can be made'' if it is mentioned explicitly in
+the makefile as a target or a prerequisite, or if an implicit rule can be
+recursively found for how to make it.  When an implicit prerequisite is the
+result of another implicit rule, we say that @dfn{chaining} is occurring.
+@xref{Chained Rules, ,Chains of Implicit Rules}.
+
+In general, @code{make} searches for an implicit rule for each target, and
+for each double-colon rule, that has no commands.  A file that is mentioned
+only as a prerequisite is considered a target whose rule specifies nothing,
+so implicit rule search happens for it.  @xref{Implicit Rule Search, ,Implicit Rule Search Algorithm}, for the
+details of how the search is done.
+
+Note that explicit prerequisites do not influence implicit rule search.
+For example, consider this explicit rule:
+
+@example
+foo.o: foo.p
+@end example
+
+@noindent
+The prerequisite on @file{foo.p} does not necessarily mean that
+@code{make} will remake @file{foo.o} according to the implicit rule to
+make an object file, a @file{.o} file, from a Pascal source file, a
+@file{.p} file.  For example, if @file{foo.c} also exists, the implicit
+rule to make an object file from a C source file is used instead,
+because it appears before the Pascal rule in the list of predefined
+implicit rules (@pxref{Catalogue of Rules, , Catalogue of Implicit
+Rules}).
+
+If you do not want an implicit rule to be used for a target that has no
+commands, you can give that target empty commands by writing a semicolon
+(@pxref{Empty Commands, ,Defining Empty Commands}).
+
+@node Catalogue of Rules, Implicit Variables, Using Implicit, Implicit Rules
+@section Catalogue of Implicit Rules
+@cindex implicit rule, predefined
+@cindex rule, implicit, predefined
+
+Here is a catalogue of predefined implicit rules which are always
+available unless the makefile explicitly overrides or cancels them.
+@xref{Canceling Rules, ,Canceling Implicit Rules}, for information on
+canceling or overriding an implicit rule.  The @samp{-r} or
+@samp{--no-builtin-rules} option cancels all predefined rules.
+
+Not all of these rules will always be defined, even when the @samp{-r}
+option is not given.  Many of the predefined implicit rules are
+implemented in @code{make} as suffix rules, so which ones will be
+defined depends on the @dfn{suffix list} (the list of prerequisites of
+the special target @code{.SUFFIXES}).  The default suffix list is:
+@code{.out}, @code{.a}, @code{.ln}, @code{.o}, @code{.c}, @code{.cc},
+@code{.C}, @code{.p}, @code{.f}, @code{.F}, @code{.r}, @code{.y},

+command used is @w{@samp{$(CC) $(LDFLAGS) @var{n}.o $(LOADLIBES) $(LDLIBS)}}.
+
+This rule does the right thing for a simple program with only one
+source file.  It will also do the right thing if there are multiple
+object files (presumably coming from various other source files), one
+of which has a name matching that of the executable file.  Thus,
+
+@example
+x: y.o z.o
+@end example
+
+@noindent
+when @file{x.c}, @file{y.c} and @file{z.c} all exist will execute:
+
+@example
+@group
+cc -c x.c -o x.o
+cc -c y.c -o y.o
+cc -c z.c -o z.o
+cc x.o y.o z.o -o x
+rm -f x.o
+rm -f y.o
+rm -f z.o
+@end group
+@end example
+
+@noindent
+In more complicated cases, such as when there is no object file whose
+name derives from the executable file name, you must write an explicit
+command for linking.
+
+Each kind of file automatically made into @samp{.o} object files will
+be automatically linked by using the compiler (@samp{$(CC)},
+@samp{$(FC)} or @samp{$(PC)}; the C compiler @samp{$(CC)} is used to
+assemble @samp{.s} files) without the @samp{-c} option.  This could be
+done by using the @samp{.o} object files as intermediates, but it is
+faster to do the compiling and linking in one step, so that's how it's
+done.@refill

+@end table
+
+Usually, you want to change only the variables listed in the table
+above, which are documented in the following section.
+
+However, the commands in built-in implicit rules actually use
+variables such as @code{COMPILE.c}, @code{LINK.p}, and
+@code{PREPROCESS.S}, whose values contain the commands listed above.
+
+@code{make} follows the convention that the rule to compile a
+@file{.@var{x}} source file uses the variable @code{COMPILE.@var{x}}.
+Similarly, the rule to produce an executable from a @file{.@var{x}}
+file uses @code{LINK.@var{x}}; and the rule to preprocess a
+@file{.@var{x}} file uses @code{PREPROCESS.@var{x}}.
+
+@vindex OUTPUT_OPTION
+Every rule that produces an object file uses the variable
+@code{OUTPUT_OPTION}.  @code{make} defines this variable either to
+contain @samp{-o $@@}, or to be empty, depending on a compile-time
+option.  You need the @samp{-o} option to ensure that the output goes
+into the right file when the source file is in a different directory,
+as when using @code{VPATH} (@pxref{Directory Search}).  However,
+compilers on some systems do not accept a @samp{-o} switch for object
+files.  If you use such a system, and use @code{VPATH}, some
+compilations will put their output in the wrong place.
+A possible workaround for this problem is to give @code{OUTPUT_OPTION}
+the value @w{@samp{; mv $*.o $@@}}.

+@section Variables Used by Implicit Rules
+@cindex flags for compilers
+
+The commands in built-in implicit rules make liberal use of certain
+predefined variables.  You can alter these variables in the makefile,
+with arguments to @code{make}, or in the environment to alter how the
+implicit rules work without redefining the rules themselves.  You can
+cancel all variables used by implicit rules with the @samp{-R} or
+@samp{--no-builtin-variables} option.
+
+For example, the command used to compile a C source file actually says
+@samp{$(CC) -c $(CFLAGS) $(CPPFLAGS)}.  The default values of the variables
+used are @samp{cc} and nothing, resulting in the command @samp{cc -c}.  By
+redefining @samp{CC} to @samp{ncc}, you could cause @samp{ncc} to be
+used for all C compilations performed by the implicit rule.  By redefining
+@samp{CFLAGS} to be @samp{-g}, you could pass the @samp{-g} option to
+each compilation.  @emph{All} implicit rules that do C compilation use
+@samp{$(CC)} to get the program name for the compiler and @emph{all}
+include @samp{$(CFLAGS)} among the arguments given to the compiler.@refill
+
+The variables used in implicit rules fall into two classes: those that are
+names of programs (like @code{CC}) and those that contain arguments for the
+programs (like @code{CFLAGS}).  (The ``name of a program'' may also contain
+some command arguments, but it must start with an actual executable program
+name.)  If a variable value contains more than one argument, separate them
+with spaces.

+
+@cindex chains of rules
+@cindex rule, implicit, chains of
+Sometimes a file can be made by a sequence of implicit rules.  For example,
+a file @file{@var{n}.o} could be made from @file{@var{n}.y} by running
+first Yacc and then @code{cc}.  Such a sequence is called a @dfn{chain}.
+
+If the file @file{@var{n}.c} exists, or is mentioned in the makefile, no
+special searching is required: @code{make} finds that the object file can
+be made by C compilation from @file{@var{n}.c}; later on, when considering
+how to make @file{@var{n}.c}, the rule for running Yacc is
+used.  Ultimately both @file{@var{n}.c} and @file{@var{n}.o} are
+updated.@refill
+
+@cindex intermediate files
+@cindex files, intermediate
+However, even if @file{@var{n}.c} does not exist and is not mentioned,
+@code{make} knows how to envision it as the missing link between
+@file{@var{n}.o} and @file{@var{n}.y}!  In this case, @file{@var{n}.c} is
+called an @dfn{intermediate file}.  Once @code{make} has decided to use the
+intermediate file, it is entered in the data base as if it had been
+mentioned in the makefile, along with the implicit rule that says how to
+create it.@refill
+
+Intermediate files are remade using their rules just like all other
+files.  But intermediate files are treated differently in two ways.
+
+The first difference is what happens if the intermediate file does not
+exist.  If an ordinary file @var{b} does not exist, and @code{make}
+considers a target that depends on @var{b}, it invariably creates
+@var{b} and then updates the target from @var{b}.  But if @var{b} is an
+intermediate file, then @code{make} can leave well enough alone.  It
+won't bother updating @var{b}, or the ultimate target, unless some
+prerequisite of @var{b} is newer than that target or there is some other
+reason to update that target.
+
+The second difference is that if @code{make} @emph{does} create @var{b}
+in order to update something else, it deletes @var{b} later on after it
+is no longer needed.  Therefore, an intermediate file which did not
+exist before @code{make} also does not exist after @code{make}.
+@code{make} reports the deletion to you by printing a @samp{rm -f}
+command showing which file it is deleting.
+
+Ordinarily, a file cannot be intermediate if it is mentioned in the
+makefile as a target or prerequisite.  However, you can explicitly mark a
+file as intermediate by listing it as a prerequisite of the special target
+@code{.INTERMEDIATE}.  This takes effect even if the file is mentioned
+explicitly in some other way.
+
+@cindex intermediate files, preserving
+@cindex preserving intermediate files
+@cindex secondary files
+You can prevent automatic deletion of an intermediate file by marking it
+as a @dfn{secondary} file.  To do this, list it as a prerequisite of the
+special target @code{.SECONDARY}.  When a file is secondary, @code{make}
+will not create the file merely because it does not already exist, but
+@code{make} does not automatically delete the file.  Marking a file as
+secondary also marks it as intermediate.
+
+You can list the target pattern of an implicit rule (such as @samp{%.o})
+as a prerequisite of the special target @code{.PRECIOUS} to preserve
+intermediate files made by implicit rules whose target patterns match
+that file's name; see @ref{Interrupts}.@refill
+@cindex preserving with @code{.PRECIOUS}
+@cindex @code{.PRECIOUS} intermediate files
+
+A chain can involve more than two implicit rules.  For example, it is
+possible to make a file @file{foo} from @file{RCS/foo.y,v} by running RCS,
+Yacc and @code{cc}.  Then both @file{foo.y} and @file{foo.c} are
+intermediate files that are deleted at the end.@refill
+
+No single implicit rule can appear more than once in a chain.  This means
+that @code{make} will not even consider such a ridiculous thing as making
+@file{foo} from @file{foo.o.o} by running the linker twice.  This
+constraint has the added benefit of preventing any infinite loop in the
+search for an implicit rule chain.
+
+There are some special implicit rules to optimize certain cases that would
+otherwise be handled by rule chains.  For example, making @file{foo} from
+@file{foo.c} could be handled by compiling and linking with separate
+chained rules, using @file{foo.o} as an intermediate file.  But what
+actually happens is that a special rule for this case does the compilation
+and linking with a single @code{cc} command.  The optimized rule is used in
+preference to the step-by-step chain because it comes earlier in the
+ordering of rules.
+
+@node Pattern Rules, Last Resort, Chained Rules, Implicit Rules
+@section Defining and Redefining Pattern Rules
+
+You define an implicit rule by writing a @dfn{pattern rule}.  A pattern
+rule looks like an ordinary rule, except that its target contains the
+character @samp{%} (exactly one of them).  The target is considered a
+pattern for matching file names; the @samp{%} can match any nonempty
+substring, while other characters match only themselves.  The prerequisites
+likewise use @samp{%} to show how their names relate to the target name.
+
+Thus, a pattern rule @samp{%.o : %.c} says how to make any file
+@file{@var{stem}.o} from another file @file{@var{stem}.c}.@refill
+
+Note that expansion using @samp{%} in pattern rules occurs
+@strong{after} any variable or function expansions, which take place
+when the makefile is read.  @xref{Using Variables, , How to Use

+@subsection Introduction to Pattern Rules
+@cindex pattern rule
+@cindex rule, pattern
+
+A pattern rule contains the character @samp{%} (exactly one of them)
+in the target; otherwise, it looks exactly like an ordinary rule.  The
+target is a pattern for matching file names; the @samp{%} matches any
+nonempty substring, while other characters match only themselves.
+@cindex target pattern, implicit
+@cindex @code{%}, in pattern rules
+
+For example, @samp{%.c} as a pattern matches any file name that ends in
+@samp{.c}.  @samp{s.%.c} as a pattern matches any file name that starts
+with @samp{s.}, ends in @samp{.c} and is at least five characters long.
+(There must be at least one character to match the @samp{%}.)  The substring
+that the @samp{%} matches is called the @dfn{stem}.@refill
+
+@samp{%} in a prerequisite of a pattern rule stands for the same stem
+that was matched by the @samp{%} in the target.  In order for
+the pattern rule to apply, its target pattern must match the file name
+under consideration, and its prerequisite patterns must name files that
+exist or can be made.  These files become prerequisites of the target.
+@cindex prerequisite pattern, implicit
+
+Thus, a rule of the form
+
+@example
+%.o : %.c ; @var{command}@dots{}
+@end example
+
+@noindent
+specifies how to make a file @file{@var{n}.o}, with another file
+@file{@var{n}.c} as its prerequisite, provided that @file{@var{n}.c}
+exists or can be made.
+
+There may also be prerequisites that do not use @samp{%}; such a prerequisite
+attaches to every file made by this pattern rule.  These unvarying
+prerequisites are useful occasionally.
+
+A pattern rule need not have any prerequisites that contain @samp{%}, or
+in fact any prerequisites at all.  Such a rule is effectively a general
+wildcard.  It provides a way to make any file that matches the target
+pattern.  @xref{Last Resort}.
+
+@c !!! The end of of this paragraph should be rewritten.  --bob
+Pattern rules may have more than one target.  Unlike normal rules, this
+does not act as many different rules with the same prerequisites and
+commands.  If a pattern rule has multiple targets, @code{make} knows that
+the rule's commands are responsible for making all of the targets.  The
+commands are executed only once to make all the targets.  When searching
+for a pattern rule to match a target, the target patterns of a rule other
+than the one that matches the target in need of a rule are incidental:
+@code{make} worries only about giving commands and prerequisites to the file
+presently in question.  However, when this file's commands are run, the
+other targets are marked as having been updated themselves.
+@cindex multiple targets, in pattern rule
+@cindex target, multiple in pattern rule
+
+The order in which pattern rules appear in the makefile is important
+since this is the order in which they are considered.
+Of equally applicable
+rules, only the first one found is used.  The rules you write take precedence
+over those that are built in.  Note however, that a rule whose
+prerequisites actually exist or are mentioned always takes priority over a
+rule with prerequisites that must be made by chaining other implicit rules.

+@subsection Pattern Rule Examples
+
+Here are some examples of pattern rules actually predefined in
+@code{make}.  First, the rule that compiles @samp{.c} files into @samp{.o}
+files:@refill
+
+@example
+%.o : %.c
+        $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@@
+@end example
+
+@noindent
+defines a rule that can make any file @file{@var{x}.o} from
+@file{@var{x}.c}.  The command uses the automatic variables @samp{$@@} and
+@samp{$<} to substitute the names of the target file and the source file
+in each case where the rule applies (@pxref{Automatic Variables}).@refill
+
+Here is a second built-in rule:
+
+@example
+% :: RCS/%,v
+        $(CO) $(COFLAGS) $<
+@end example
+
+@noindent
+defines a rule that can make any file @file{@var{x}} whatsoever from a
+corresponding file @file{@var{x},v} in the subdirectory @file{RCS}.  Since
+the target is @samp{%}, this rule will apply to any file whatever, provided
+the appropriate prerequisite file exists.  The double colon makes the rule
+@dfn{terminal}, which means that its prerequisite may not be an intermediate
+file (@pxref{Match-Anything Rules, ,Match-Anything Pattern Rules}).@refill
+
+@need 500
+This pattern rule has two targets:
+
+@example
+@group
+%.tab.c %.tab.h: %.y
+        bison -d $<
+@end group
+@end example
+
+@noindent
+@c The following paragraph is rewritten to avoid overfull hboxes
+This tells @code{make} that the command @samp{bison -d @var{x}.y} will
+make both @file{@var{x}.tab.c} and @file{@var{x}.tab.h}.  If the file
+@file{foo} depends on the files @file{parse.tab.o} and @file{scan.o}
+and the file @file{scan.o} depends on the file @file{parse.tab.h},
+when @file{parse.y} is changed, the command @samp{bison -d parse.y}
+will be executed only once, and the prerequisites of both
+@file{parse.tab.o} and @file{scan.o} will be satisfied.  (Presumably
+the file @file{parse.tab.o} will be recompiled from @file{parse.tab.c}
+and the file @file{scan.o} from @file{scan.c}, while @file{foo} is
+linked from @file{parse.tab.o}, @file{scan.o}, and its other
+prerequisites, and it will execute happily ever after.)@refill

+@subsection Automatic Variables
+@cindex automatic variables
+@cindex variables, automatic
+@cindex variables, and implicit rule
+
+Suppose you are writing a pattern rule to compile a @samp{.c} file into a
+@samp{.o} file: how do you write the @samp{cc} command so that it operates
+on the right source file name?  You cannot write the name in the command,
+because the name is different each time the implicit rule is applied.
+
+What you do is use a special feature of @code{make}, the @dfn{automatic
+variables}.  These variables have values computed afresh for each rule that
+is executed, based on the target and prerequisites of the rule.  In this
+example, you would use @samp{$@@} for the object file name and @samp{$<}
+for the source file name.
+
+@cindex automatic variables in prerequisites
+@cindex prerequisites, and automatic variables
+It's very important that you recognize the limited scope in which
+automatic variable values are available: they only have values within
+the command script.  In particular, you cannot use them anywhere
+within the target or prerequisite lists of a rule; they have no value
+there and will expand to the empty string.  A common mistake is
+attempting to use @code{$@@} within the prerequisites list in a rule;
+this will not work.  However, see below for information on the
+SysV-style @code{$$@@} variables.
+
+Here is a table of automatic variables:
+
+@table @code
+@vindex $@@
+@vindex @@ @r{(automatic variable)}
+@item $@@
+The file name of the target of the rule.  If the target is an archive
+member, then @samp{$@@} is the name of the archive file.  In a pattern
+rule that has multiple targets (@pxref{Pattern Intro, ,Introduction to
+Pattern Rules}), @samp{$@@} is the name of whichever target caused the
+rule's commands to be run.
+
+@vindex $%
+@vindex % @r{(automatic variable)}
+@item $%
+The target member name, when the target is an archive member.
+@xref{Archives}.  For example, if the target is @file{foo.a(bar.o)} then
+@samp{$%} is @file{bar.o} and @samp{$@@} is @file{foo.a}.  @samp{$%} is
+empty when the target is not an archive member.
+
+@vindex $<
+@vindex < @r{(automatic variable)}
+@item $<
+The name of the first prerequisite.  If the target got its commands from
+an implicit rule, this will be the first prerequisite added by the
+implicit rule (@pxref{Implicit Rules}).
+
+@vindex $?
+@vindex ? @r{(automatic variable)}
+@item $?
+The names of all the prerequisites that are newer than the target, with
+spaces between them.  For prerequisites which are archive members, only
+the member named is used (@pxref{Archives}).
+@cindex prerequisites, list of changed
+@cindex list of changed prerequisites
+
+@vindex $^
+@vindex ^ @r{(automatic variable)}
+@item $^
+The names of all the prerequisites, with spaces between them.  For
+prerequisites which are archive members, only the member named is used
+(@pxref{Archives}).  A target has only one prerequisite on each other file
+it depends on, no matter how many times each file is listed as a
+prerequisite.  So if you list a prerequisite more than once for a target,
+the value of @code{$^} contains just one copy of the name.
+@cindex prerequisites, list of all
+@cindex list of all prerequisites
+
+@vindex $+

+This is like @samp{$^}, but prerequisites listed more than once are

+(@pxref{Suffix Rules, ,Old-Fashioned Suffix Rules}), @samp{$*} is set to
+the target name minus the suffix.  For example, if the target name is
+@samp{foo.c}, then @samp{$*} is set to @samp{foo}, since @samp{.c} is a
+suffix.  GNU @code{make} does this bizarre thing only for compatibility
+with other implementations of @code{make}.  You should generally avoid

+@samp{$?} is useful even in explicit rules when you wish to operate on only
+the prerequisites that have changed.  For example, suppose that an archive

+have variants that get just the file's directory name or just the file
+name within the directory.  The variant variables' names are formed by
+appending @samp{D} or @samp{F}, respectively.  These variants are
+semi-obsolete in GNU @code{make} since the functions @code{dir} and

+@subsection How Patterns Match
+
+@cindex stem
+A target pattern is composed of a @samp{%} between a prefix and a suffix,
+either or both of which may be empty.  The pattern matches a file name only
+if the file name starts with the prefix and ends with the suffix, without
+overlap.  The text between the prefix and the suffix is called the
+@dfn{stem}.  Thus, when the pattern @samp{%.o} matches the file name
+@file{test.o}, the stem is @samp{test}.  The pattern rule prerequisites are
+turned into actual file names by substituting the stem for the character
+@samp{%}.  Thus, if in the same example one of the prerequisites is written
+as @samp{%.c}, it expands to @samp{test.c}.@refill
+
+When the target pattern does not contain a slash (and it usually does
+not), directory names in the file names are removed from the file name
+before it is compared with the target prefix and suffix.  After the
+comparison of the file name to the target pattern, the directory
+names, along with the slash that ends them, are added on to the
+prerequisite file names generated from the pattern rule's prerequisite
+patterns and the file name. The directories are ignored only for the
+purpose of finding an implicit rule to use, not in the application of
+that rule.  Thus, @samp{e%t} matches the file name @file{src/eat},
+with @samp{src/a} as the stem.  When prerequisites are turned into file
+names, the directories from the stem are added at the front, while the
+rest of the stem is substituted for the @samp{%}.  The stem
+@samp{src/a} with a prerequisite pattern @samp{c%r} gives the file name
+@file{src/car}.@refill

+@node Match-Anything Rules, Canceling Rules, Pattern Match, Pattern Rules
+@subsection Match-Anything Pattern Rules
+
+@cindex match-anything rule
+@cindex terminal rule
+When a pattern rule's target is just @samp{%}, it matches any file name
+whatever.  We call these rules @dfn{match-anything} rules.  They are very
+useful, but it can take a lot of time for @code{make} to think about them,
+because it must consider every such rule for each file name listed either
+as a target or as a prerequisite.
+
+Suppose the makefile mentions @file{foo.c}.  For this target, @code{make}
+would have to consider making it by linking an object file @file{foo.c.o},
+or by C compilation-and-linking in one step from @file{foo.c.c}, or by
+Pascal compilation-and-linking from @file{foo.c.p}, and many other
+possibilities.
+
+We know these possibilities are ridiculous since @file{foo.c} is a C source
+file, not an executable.  If @code{make} did consider these possibilities,
+it would ultimately reject them, because files such as @file{foo.c.o} and
+@file{foo.c.p} would not exist.  But these possibilities are so
+numerous that @code{make} would run very slowly if it had to consider
+them.@refill
+
+To gain speed, we have put various constraints on the way @code{make}
+considers match-anything rules.  There are two different constraints that
+can be applied, and each time you define a match-anything rule you must
+choose one or the other for that rule.
+
+One choice is to mark the match-anything rule as @dfn{terminal} by defining
+it with a double colon.  When a rule is terminal, it does not apply unless
+its prerequisites actually exist.  Prerequisites that could be made with
+other implicit rules are not good enough.  In other words, no further
+chaining is allowed beyond a terminal rule.
+
+For example, the built-in implicit rules for extracting sources from RCS
+and SCCS files are terminal; as a result, if the file @file{foo.c,v} does
+not exist, @code{make} will not even consider trying to make it as an
+intermediate file from @file{foo.c,v.o} or from @file{RCS/SCCS/s.foo.c,v}.
+RCS and SCCS files are generally ultimate source files, which should not be
+remade from any other files; therefore, @code{make} can save time by not
+looking for ways to remake them.@refill
+
+If you do not mark the match-anything rule as terminal, then it is
+nonterminal.  A nonterminal match-anything rule cannot apply to a file name
+that indicates a specific type of data.  A file name indicates a specific
+type of data if some non-match-anything implicit rule target matches it.
+
+For example, the file name @file{foo.c} matches the target for the pattern
+rule @samp{%.c : %.y} (the rule to run Yacc).  Regardless of whether this
+rule is actually applicable (which happens only if there is a file
+@file{foo.y}), the fact that its target matches is enough to prevent
+consideration of any nonterminal match-anything rules for the file
+@file{foo.c}.  Thus, @code{make} will not even consider trying to make
+@file{foo.c} as an executable file from @file{foo.c.o}, @file{foo.c.c},
+@file{foo.c.p}, etc.@refill
+
+The motivation for this constraint is that nonterminal match-anything
+rules are used for making files containing specific types of data (such as
+executable files) and a file name with a recognized suffix indicates some
+other specific type of data (such as a C source file).
+
+Special built-in dummy pattern rules are provided solely to recognize
+certain file names so that nonterminal match-anything rules will not be
+considered.  These dummy rules have no prerequisites and no commands, and
+they are ignored for all other purposes.  For example, the built-in
+implicit rule
+
+@example
+%.p :
+@end example
+
+@noindent
+exists to make sure that Pascal source files such as @file{foo.p} match a
+specific target pattern and thereby prevent time from being wasted looking
+for @file{foo.p.o} or @file{foo.p.c}.
+
+Dummy pattern rules such as the one for @samp{%.p} are made for every
+suffix listed as valid for use in suffix rules (@pxref{Suffix Rules, ,Old-Fashioned Suffix Rules}).

+
+You can override a built-in implicit rule (or one you have defined
+yourself) by defining a new pattern rule with the same target and
+prerequisites, but different commands.  When the new rule is defined, the
+built-in one is replaced.  The new rule's position in the sequence of
+implicit rules is determined by where you write the new rule.
+
+You can cancel a built-in implicit rule by defining a pattern rule with the
+same target and prerequisites, but no commands.  For example, the following

+You can define a last-resort implicit rule by writing a terminal
+match-anything pattern rule with no prerequisites (@pxref{Match-Anything
+Rules}).  This is just like any other pattern rule; the only thing
+special about it is that it will match any target.  So such a rule's
+commands are used for all targets and prerequisites that have no commands
+of their own and for which no other implicit rule applies.
+
+For example, when testing a makefile, you might not care if the source
+files contain real data, only that they exist.  Then you might do this:
+
+@example
+%::
+        touch $@@
+@end example
+
+@noindent
+to cause all the source files needed (as prerequisites) to be created
+automatically.
+
+@findex .DEFAULT
+You can instead define commands to be used for targets for which there
+are no rules at all, even ones which don't specify commands.  You do
+this by writing a rule for the target @code{.DEFAULT}.  Such a rule's
+commands are used for all prerequisites which do not appear as targets in
+any explicit rule, and for which no implicit rule applies.  Naturally,
+there is no @code{.DEFAULT} rule unless you write one.
+
+If you use @code{.DEFAULT} with no commands or prerequisites:

+@example
+.DEFAULT:
+@end example
+
+@noindent
+the commands previously stored for @code{.DEFAULT} are cleared.
+Then @code{make} acts as if you had never defined @code{.DEFAULT} at all.

+to be run for the target, you can give it empty commands (@pxref{Empty

+@node Suffix Rules, Implicit Rule Search, Last Resort, Implicit Rules
+@section Old-Fashioned Suffix Rules
+@cindex old-fashioned suffix rules
+@cindex suffix rule
+
+@dfn{Suffix rules} are the old-fashioned way of defining implicit rules for
+@code{make}.  Suffix rules are obsolete because pattern rules are more
+general and clearer.  They are supported in GNU @code{make} for
+compatibility with old makefiles.  They come in two kinds:
+@dfn{double-suffix} and @dfn{single-suffix}.@refill
+
+A double-suffix rule is defined by a pair of suffixes: the target suffix
+and the source suffix.  It matches any file whose name ends with the
+target suffix.  The corresponding implicit prerequisite is made by
+replacing the target suffix with the source suffix in the file name.  A
+two-suffix rule whose target and source suffixes are @samp{.o} and
+@samp{.c} is equivalent to the pattern rule @samp{%.o : %.c}.
+
+A single-suffix rule is defined by a single suffix, which is the source
+suffix.  It matches any file name, and the corresponding implicit
+prerequisite name is made by appending the source suffix.  A single-suffix
+rule whose source suffix is @samp{.c} is equivalent to the pattern rule
+@samp{% : %.c}.
+
+Suffix rule definitions are recognized by comparing each rule's target
+against a defined list of known suffixes.  When @code{make} sees a rule
+whose target is a known suffix, this rule is considered a single-suffix
+rule.  When @code{make} sees a rule whose target is two known suffixes
+concatenated, this rule is taken as a double-suffix rule.
+
+For example, @samp{.c} and @samp{.o} are both on the default list of
+known suffixes.  Therefore, if you define a rule whose target is
+@samp{.c.o}, @code{make} takes it to be a double-suffix rule with source
+suffix @samp{.c} and target suffix @samp{.o}.  Here is the old-fashioned
+way to define the rule for compiling a C source file:@refill
+
+@example
+.c.o:
+        $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@@ $<
+@end example
+
+Suffix rules cannot have any prerequisites of their own.  If they have any,
+they are treated as normal files with funny names, not as suffix rules.
+Thus, the rule:
+
+@example
+.c.o: foo.h
+        $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@@ $<
+@end example
+
+@noindent
+tells how to make the file @file{.c.o} from the prerequisite file
+@file{foo.h}, and is not at all like the pattern rule:
+
+@example
+%.o: %.c foo.h
+        $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@@ $<
+@end example
+
+@noindent
+which tells how to make @samp{.o} files from @samp{.c} files, and makes all
+@samp{.o} files using this pattern rule also depend on @file{foo.h}.
+
+Suffix rules with no commands are also meaningless.  They do not remove
+previous rules as do pattern rules with no commands (@pxref{Canceling
+Rules, , Canceling Implicit Rules}).  They simply enter the suffix or pair of suffixes concatenated as
+a target in the data base.@refill
+
+@findex .SUFFIXES
+The known suffixes are simply the names of the prerequisites of the special
+target @code{.SUFFIXES}.  You can add your own suffixes by writing a rule
+for @code{.SUFFIXES} that adds more prerequisites, as in:
+
+@example
+.SUFFIXES: .hack .win
+@end example
+
+@noindent
+which adds @samp{.hack} and @samp{.win} to the end of the list of suffixes.
+
+If you wish to eliminate the default known suffixes instead of just adding
+to them, write a rule for @code{.SUFFIXES} with no prerequisites.  By
+special dispensation, this eliminates all existing prerequisites of
+@code{.SUFFIXES}.  You can then write another rule to add the suffixes you
+want.  For example,
+
+@example
+@group
+.SUFFIXES:            # @r{Delete the default suffixes}
+.SUFFIXES: .c .o .h   # @r{Define our suffix list}
+@end group
+@end example
+
+The @samp{-r} or @samp{--no-builtin-rules} flag causes the default
+list of suffixes to be empty.
+
+@vindex SUFFIXES
+The variable @code{SUFFIXES} is defined to the default list of suffixes
+before @code{make} reads any makefiles.  You can change the list of suffixes
+with a rule for the special target @code{.SUFFIXES}, but that does not alter
+this variable.

+@section Archive Members as Targets
+@cindex archive member targets
+
+An individual member of an archive file can be used as a target or
+prerequisite in @code{make}.  You specify the member named @var{member} in
+archive file @var{archive} as follows:
+
+@example
+@var{archive}(@var{member})
+@end example
+
+@noindent
+This construct is available only in targets and prerequisites, not in
+commands!  Most programs that you might use in commands do not support this
+syntax and cannot act directly on archive members.  Only @code{ar} and
+other programs specifically designed to operate on archives can do so.
+Therefore, valid commands to update an archive member target probably must
+use @code{ar}.  For example, this rule says to create a member
+@file{hack.o} in archive @file{foolib} by copying the file @file{hack.o}:
+
+@example
+foolib(hack.o) : hack.o
+        ar cr foolib hack.o
+@end example
+
+In fact, nearly all archive member targets are updated in just this way
+and there is an implicit rule to do it for you.  @strong{Note:} The
+@samp{c} flag to @code{ar} is required if the archive file does not
+already exist.
+
+To specify several members in the same archive, you can write all the
+member names together between the parentheses.  For example:
+
+@example
+foolib(hack.o kludge.o)
+@end example
+
+@noindent
+is equivalent to:
+
+@example
+foolib(hack.o) foolib(kludge.o)
+@end example

+@cindex wildcard, in archive member
+You can also use shell-style wildcards in an archive member reference.

+@section Implicit Rule for Archive Member Targets
+
+Recall that a target that looks like @file{@var{a}(@var{m})} stands for the
+member named @var{m} in the archive file @var{a}.
+
+When @code{make} looks for an implicit rule for such a target, as a special
+feature it considers implicit rules that match @file{(@var{m})}, as well as
+those that match the actual target @file{@var{a}(@var{m})}.
+
+This causes one special rule whose target is @file{(%)} to match.  This
+rule updates the target @file{@var{a}(@var{m})} by copying the file @var{m}
+into the archive.  For example, it will update the archive member target
+@file{foo.a(bar.o)} by copying the @emph{file} @file{bar.o} into the
+archive @file{foo.a} as a @emph{member} named @file{bar.o}.
+
+When this rule is chained with others, the result is very powerful.
+Thus, @samp{make "foo.a(bar.o)"} (the quotes are needed to protect the
+@samp{(} and @samp{)} from being interpreted specially by the shell) in
+the presence of a file @file{bar.c} is enough to cause the following
+commands to be run, even without a makefile:
+
+@example
+cc -c bar.c -o bar.o
+ar r foo.a bar.o
+rm -f bar.o
+@end example
+
+@noindent
+Here @code{make} has envisioned the file @file{bar.o} as an intermediate
+file.  @xref{Chained Rules, ,Chains of Implicit Rules}.
+
+Implicit rules such as this one are written using the automatic variable
+@samp{$%}.  @xref{Automatic Variables}.
+
+An archive member name in an archive cannot contain a directory name, but
+it may be useful in a makefile to pretend that it does.  If you write an
+archive member target @file{foo.a(dir/file.o)}, @code{make} will perform
+automatic updating with this command:
+
+@example
+ar r foo.a dir/file.o
+@end example
+
+@noindent
+which has the effect of copying the file @file{dir/file.o} into a member
+named @file{file.o}.  In connection with such usage, the automatic variables
+@code{%D} and @code{%F} may be useful.

+@cindex directories, updating archive symbol
+
+An archive file that is used as a library usually contains a special member
+named @file{__.SYMDEF} that contains a directory of the external symbol
+names defined by all the other members.  After you update any other
+members, you need to update @file{__.SYMDEF} so that it will summarize the
+other members properly.  This is done by running the @code{ranlib} program:
+
+@example
+ranlib @var{archivefile}
+@end example
+
+Normally you would put this command in the rule for the archive file,
+and make all the members of the archive file prerequisites of that rule.
+For example,
+
+@example
+libfoo.a: libfoo.a(x.o) libfoo.a(y.o) @dots{}
+        ranlib libfoo.a
+@end example
+
+@noindent
+The effect of this is to update archive members @file{x.o}, @file{y.o},
+etc., and then update the symbol directory member @file{__.SYMDEF} by
+running @code{ranlib}.  The rules for updating the members are not shown
+here; most likely you can omit them and use the implicit rule which copies
+files into the archive, as described in the preceding section.
+
+This is not necessary when using the GNU @code{ar} program, which
+updates the @file{__.SYMDEF} member automatically.

+@cindex @code{-j}, and archive update
+
+It is important to be careful when using parallel execution (the
+@code{-j} switch; @pxref{Parallel, ,Parallel Execution}) and archives.
+If multiple @code{ar} commands run at the same time on the same archive
+file, they will not know about each other and can corrupt the file.
+
+Possibly a future version of @code{make} will provide a mechanism to
+circumvent this problem by serializing all commands that operate on the
+same archive file.  But for the time being, you must either write your
+makefiles to avoid this problem in some other way, or not use @code{-j}.
+
+@node Archive Suffix Rules,  , Archive Pitfalls, Archives
+@section Suffix Rules for Archive Files
+@cindex suffix rule, for archive
+@cindex archive, suffix rule for
+@cindex library archive, suffix rule for
+@cindex @code{.a} (archives)
+
+You can write a special kind of suffix rule for dealing with archive
+files.  @xref{Suffix Rules}, for a full explanation of suffix rules.
+Archive suffix rules are obsolete in GNU @code{make}, because pattern
+rules for archives are a more general mechanism (@pxref{Archive
+Update}).  But they are retained for compatibility with other
+@code{make}s.
+
+To write a suffix rule for archives, you simply write a suffix rule
+using the target suffix @samp{.a} (the usual suffix for archive files).
+For example, here is the old-fashioned suffix rule to update a library
+archive from C source files:
+
+@example
+@group
+.c.a:
+        $(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $*.o
+        $(AR) r $@@ $*.o
+        $(RM) $*.o
+@end group
+@end example
+
+@noindent
+This works just as if you had written the pattern rule:
+
+@example
+@group
+(%.o): %.c
+        $(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $*.o
+        $(AR) r $@@ $*.o
+        $(RM) $*.o
+@end group
+@end example
+
+In fact, this is just what @code{make} does when it sees a suffix rule
+with @samp{.a} as the target suffix.  Any double-suffix rule
+@w{@samp{.@var{x}.a}} is converted to a pattern rule with the target
+pattern @samp{(%.o)} and a prerequisite pattern of @samp{%.@var{x}}.
+
+Since you might want to use @samp{.a} as the suffix for some other kind
+of file, @code{make} also converts archive suffix rules to pattern rules
+in the normal way (@pxref{Suffix Rules}).  Thus a double-suffix rule
+@w{@samp{.@var{x}.a}} produces two pattern rules: @samp{@w{(%.o):}
+@w{%.@var{x}}} and @samp{@w{%.a}: @w{%.@var{x}}}.@refill

+@cindex portability
+@cindex compatibility
+
+Here is a summary of the features of GNU @code{make}, for comparison
+with and credit to other versions of @code{make}.  We consider the
+features of @code{make} in 4.2 BSD systems as a baseline.  If you are
+concerned with writing portable makefiles, you should not use the
+features of @code{make} listed here, nor the ones in @ref{Missing}.
+
+Many features come from the version of @code{make} in System V.
+
+@itemize @bullet
+@item
+The @code{VPATH} variable and its special meaning.
+@xref{Directory Search, , Searching Directories for Prerequisites}.
+This feature exists in System V @code{make}, but is undocumented.
+It is documented in 4.3 BSD @code{make} (which says it mimics System V's
+@code{VPATH} feature).@refill
+
+@item
+Included makefiles.  @xref{Include, ,Including Other Makefiles}.
+Allowing multiple files to be included with a single directive is a GNU
+extension.
+
+@item
+Variables are read from and communicated via the environment.
+@xref{Environment, ,Variables from the Environment}.
+
+@item
+Options passed through the variable @code{MAKEFLAGS} to recursive
+invocations of @code{make}.
+@xref{Options/Recursion, ,Communicating Options to a Sub-@code{make}}.
+
+@item
+The automatic variable @code{$%} is set to the member name
+in an archive reference.  @xref{Automatic Variables}.
+
+@item
+The automatic variables @code{$@@}, @code{$*}, @code{$<}, @code{$%},
+and @code{$?} have corresponding forms like @code{$(@@F)} and
+@code{$(@@D)}.  We have generalized this to @code{$^} as an obvious
+extension.  @xref{Automatic Variables}.@refill
+
+@item
+Substitution variable references.
+@xref{Reference, ,Basics of Variable References}.
+
+@item
+The command-line options @samp{-b} and @samp{-m}, accepted and
+ignored.  In System V @code{make}, these options actually do something.
+
+@item
+Execution of recursive commands to run @code{make} via the variable
+@code{MAKE} even if @samp{-n}, @samp{-q} or @samp{-t} is specified.
+@xref{Recursion, ,Recursive Use of @code{make}}.
+
+@item
+Support for suffix @samp{.a} in suffix rules.  @xref{Archive Suffix
+Rules}.  This feature is obsolete in GNU @code{make}, because the
+general feature of rule chaining (@pxref{Chained Rules, ,Chains of
+Implicit Rules}) allows one pattern rule for installing members in an
+archive (@pxref{Archive Update}) to be sufficient.
+
+@item
+The arrangement of lines and backslash-newline combinations in
+commands is retained when the commands are printed, so they appear as
+they do in the makefile, except for the stripping of initial
+whitespace.
+@end itemize
+
+The following features were inspired by various other versions of
+@code{make}.  In some cases it is unclear exactly which versions inspired
+which others.
+
+@itemize @bullet
+@item
+Pattern rules using @samp{%}.
+This has been implemented in several versions of @code{make}.
+We're not sure who invented it first, but it's been spread around a bit.
+@xref{Pattern Rules, ,Defining and Redefining Pattern Rules}.@refill
+
+@item
+Rule chaining and implicit intermediate files.
+This was implemented by Stu Feldman in his version of @code{make}
+for AT&T Eighth Edition Research Unix, and later by Andrew Hume of
+AT&T Bell Labs in his @code{mk} program (where he terms it
+``transitive closure'').  We do not really know if
+we got this from either of them or thought it up ourselves at the
+same time.  @xref{Chained Rules, ,Chains of Implicit Rules}.
+
+@item
+The automatic variable @code{$^} containing a list of all prerequisites
+of the current target.  We did not invent this, but we have no idea who
+did.  @xref{Automatic Variables}.  The automatic variable
+@code{$+} is a simple extension of @code{$^}.
+
+@item
+The ``what if'' flag (@samp{-W} in GNU @code{make}) was (as far as we know)
+invented by Andrew Hume in @code{mk}.
+@xref{Instead of Execution, ,Instead of Executing the Commands}.
+
+@item
+The concept of doing several things at once (parallelism) exists in
+many incarnations of @code{make} and similar programs, though not in the
+System V or BSD implementations.  @xref{Execution, ,Command Execution}.
+
+@item
+Modified variable references using pattern substitution come from
+SunOS 4.  @xref{Reference, ,Basics of Variable References}.
+This functionality was provided in GNU @code{make} by the
+@code{patsubst} function before the alternate syntax was implemented
+for compatibility with SunOS 4.  It is not altogether clear who
+inspired whom, since GNU @code{make} had @code{patsubst} before SunOS
+4 was released.@refill
+
+@item
+The special significance of @samp{+} characters preceding command lines
+(@pxref{Instead of Execution, ,Instead of Executing the Commands}) is
+mandated by
+@cite{IEEE Standard 1003.2-1992} (POSIX.2).
+
+@item
+The @samp{+=} syntax to append to the value of a variable comes from SunOS
+4 @code{make}.  @xref{Appending, , Appending More Text to Variables}.
+
+@item
+The syntax @w{@samp{@var{archive}(@var{mem1} @var{mem2}@dots{})}} to list
+multiple members in a single archive file comes from SunOS 4 @code{make}.
+@xref{Archive Members}.
+
+@item
+The @code{-include} directive to include makefiles with no error for a
+nonexistent file comes from SunOS 4 @code{make}.  (But note that SunOS 4
+@code{make} does not allow multiple makefiles to be specified in one
+@code{-include} directive.)  The same feature appears with the name
+@code{sinclude} in SGI @code{make} and perhaps others.
+@end itemize
+
+The remaining features are inventions new in GNU @code{make}:
+
+@itemize @bullet
+@item
+Use the @samp{-v} or @samp{--version} option to print version and
+copyright information.
+
+@item
+Use the @samp{-h} or @samp{--help} option to summarize the options to
+@code{make}.
+
+@item
+Simply-expanded variables.  @xref{Flavors, ,The Two Flavors of Variables}.

+@item
+Pass command-line variable assignments automatically through the
+variable @code{MAKE} to recursive @code{make} invocations.
+@xref{Recursion, ,Recursive Use of @code{make}}.

+
+@item
+Make verbatim variable definitions with @code{define}.
+@xref{Defining, ,Defining Variables Verbatim}.
+
+@item
+Declare phony targets with the special target @code{.PHONY}.
+
+Andrew Hume of AT&T Bell Labs implemented a similar feature with a
+different syntax in his @code{mk} program.  This seems to be a case of
+parallel discovery.  @xref{Phony Targets, ,Phony Targets}.
+
+@item
+Manipulate text by calling functions.

+Use the @samp{-o} or @samp{--old-file}
+option to pretend a file's modification-time is old.
+@xref{Avoiding Compilation, ,Avoiding Recompilation of Some Files}.
+
+@item
+Conditional execution.
+
+This feature has been implemented numerous times in various versions

+of the C preprocessor and similar macro languages and is not a
+revolutionary concept.  @xref{Conditionals, ,Conditional Parts of Makefiles}.

+A target of the form @samp{@var{file}((@var{entry}))} stands for a member

+
+This feature was not put into GNU @code{make} because of the
+nonmodularity of putting knowledge into @code{make} of the internal
+format of archive file symbol tables.
+@xref{Archive Symbols, ,Updating Archive Symbol Directories}.
+
+@item
+Suffixes (used in suffix rules) that end with the character @samp{~}
+have a special meaning to System V @code{make};
+they refer to the SCCS file that corresponds
+to the file one would get without the @samp{~}.  For example, the
+suffix rule @samp{.c~.o} would make the file @file{@var{n}.o} from
+the SCCS file @file{s.@var{n}.c}.  For complete coverage, a whole
+series of such suffix rules is required.
+@xref{Suffix Rules, ,Old-Fashioned Suffix Rules}.
+
+In GNU @code{make}, this entire series of cases is handled by two
+pattern rules for extraction from SCCS, in combination with the
+general feature of rule chaining.
+@xref{Chained Rules, ,Chains of Implicit Rules}.
+
+@item
+In System V and 4.3 BSD @code{make}, files found by @code{VPATH} search
+(@pxref{Directory Search, ,Searching Directories for Prerequisites}) have their names changed inside command
+strings.  We feel it is much cleaner to always use automatic variables
+and thus make this feature obsolete.@refill
+
+@item
+In some Unix @code{make}s, the automatic variable @code{$*} appearing in
+the prerequisites of a rule has the amazingly strange ``feature'' of
+expanding to the full name of the @emph{target of that rule}.  We cannot
+imagine what went on in the minds of Unix @code{make} developers to do
+this; it is utterly inconsistent with the normal definition of @code{$*}.
+@vindex * @r{(automatic variable), unsupported bizarre usage}
+
+@item
+In some Unix @code{make}s, implicit rule search
+(@pxref{Implicit Rules, ,Using Implicit Rules}) is apparently done for
+@emph{all} targets, not just those without commands.  This means you can
+do:@refill
+
+@example
+@group
+foo.o:
+        cc -c foo.c
+@end group
+@end example
+
+@noindent
+and Unix @code{make} will intuit that @file{foo.o} depends on
+@file{foo.c}.@refill
+
+We feel that such usage is broken.  The prerequisite properties of
+@code{make} are well-defined (for GNU @code{make}, at least),
+and doing such a thing simply does not fit the model.@refill
+
+@item
+GNU @code{make} does not include any built-in implicit rules for
+compiling or preprocessing EFL programs.  If we hear of anyone who is
+using EFL, we will gladly add them.
+
+@item
+It appears that in SVR4 @code{make}, a suffix rule can be specified with
+no commands, and it is treated as if it had empty commands
+(@pxref{Empty Commands}).  For example:
+
+@example
+.c.a:
+@end example
+
+@noindent
+will override the built-in @file{.c.a} suffix rule.
+
+We feel that it is cleaner for a rule without commands to always simply
+add to the prerequisite list for the target.  The above example can be
+easily rewritten to get the desired behavior in GNU @code{make}:
+
+@example
+.c.a: ;
+@end example
+
+@item
+Some versions of @code{make} invoke the shell with the @samp{-e} flag,
+except under @samp{-k} (@pxref{Testing, ,Testing the Compilation of a
+Program}).  The @samp{-e} flag tells the shell to exit as soon as any
+program it runs returns a nonzero status.  We feel it is cleaner to
+write each shell command line to stand on its own and not require this
+special treatment.

+@appendix Errors Generated by Make
+
+Here is a list of the more common errors you might see generated by
+@code{make}, and some information about what they mean and how to fix
+them.
+
+Sometimes @code{make} errors are not fatal, especially in the presence
+of a @code{-} prefix on a command script line, or the @code{-k} command
+line option.  Errors that are fatal are prefixed with the string
+@code{***}.
+
+Error messages are all either prefixed with the name of the program
+(usually @samp{make}), or, if the error is found in a makefile, the name
+of the file and linenumber containing the problem.
+
+In the table below, these common prefixes are left off.
+
+@table @samp
+
+@item [@var{foo}] Error @var{NN}
+@itemx [@var{foo}] @var{signal description}
+These errors are not really @code{make} errors at all.  They mean that a
+program that @code{make} invoked as part of a command script returned a
+non-0 error code (@samp{Error @var{NN}}), which @code{make} interprets
+as failure, or it exited in some other abnormal fashion (with a
+signal of some type).  @xref{Errors, ,Errors in Commands}.
+
+If no @code{***} is attached to the message, then the subprocess failed
+but the rule in the makefile was prefixed with the @code{-} special
+character, so @code{make} ignored the error.
+
+@item missing separator.  Stop.
+@itemx missing separator (did you mean TAB instead of 8 spaces?).  Stop.
+This means that @code{make} could not understand much of anything about
+the command line it just read.  GNU @code{make} looks for various kinds
+of separators (@code{:}, @code{=}, TAB characters, etc.) to help it
+decide what kind of commandline it's seeing.  This means it couldn't
+find a valid one.
+
+One of the most common reasons for this message is that you (or perhaps
+your oh-so-helpful editor, as is the case with many MS-Windows editors)
+have attempted to indent your command scripts with spaces instead of a
+TAB character.  In this case, @code{make} will use the second form of
+the error above.  Remember that every line in the command script must
+begin with a TAB character.  Eight spaces do not count.  @xref{Rule
+Syntax}.
+
+@item commands commence before first target.  Stop.
+@itemx missing rule before commands.  Stop.
+This means the first thing in the makefile seems to be part of a command
+script: it begins with a TAB character and doesn't appear to be a legal
+@code{make} command (such as a variable assignment).  Command scripts
+must always be associated with a target.
+
+The second form is generated if the line has a semicolon as the first
+non-whitespace character; @code{make} interprets this to mean you left
+out the "target: prerequisite" section of a rule.  @xref{Rule Syntax}.
+
+@item No rule to make target `@var{xxx}'.
+@itemx No rule to make target `@var{xxx}', needed by `@var{yyy}'.
+This means that @code{make} decided it needed to build a target, but
+then couldn't find any instructions in the makefile on how to do that,
+either explicit or implicit (including in the default rules database).
+
+If you want that file to be built, you will need to add a rule to your
+makefile describing how that target can be built.  Other possible
+sources of this problem are typos in the makefile (if that filename is
+wrong) or a corrupted source tree (if that file is not supposed to be
+built, but rather only a prerequisite).
+
+@item No targets specified and no makefile found.  Stop.
+@itemx No targets.  Stop.
+The former means that you didn't provide any targets to be built on the
+command line, and @code{make} couldn't find any makefiles to read in.
+The latter means that some makefile was found, but it didn't contain any
+default target and none was given on the command line.  GNU @code{make}
+has nothing to do in these situations.
+@xref{Makefile Arguments, ,Arguments to Specify the Makefile}.@refill
+
+@item Makefile `@var{xxx}' was not found.
+@itemx Included makefile `@var{xxx}' was not found.
+A makefile specified on the command line (first form) or included
+(second form) was not found.
+
+@item warning: overriding commands for target `@var{xxx}'
+@itemx warning: ignoring old commands for target `@var{xxx}'
+GNU @code{make} allows commands to be specified only once per target
+(except for double-colon rules).  If you give commands for a target
+which already has been defined to have commands, this warning is issued
+and the second set of commands will overwrite the first set.
+@xref{Multiple Rules, ,Multiple Rules for One Target}.
+
+@item Circular @var{xxx} <- @var{yyy} dependency dropped.
+This means that @code{make} detected a loop in the dependency graph:
+after tracing the prerequisite @var{yyy} of target @var{xxx}, and its
+prerequisites, etc., one of them depended on @var{xxx} again.
+
+@item Recursive variable `@var{xxx}' references itself (eventually).  Stop.
+This means you've defined a normal (recursive) @code{make} variable
+@var{xxx} that, when it's expanded, will refer to itself (@var{xxx}).
+This is not allowed; either use simply-expanded variables (@code{:=}) or
+use the append operator (@code{+=}).  @xref{Using Variables, ,How to Use
+Variables}.
+
+@item Unterminated variable reference.  Stop.
+This means you forgot to provide the proper closing parenthesis
+or brace in your variable or function reference.
+
+@item insufficient arguments to function `@var{xxx}'.  Stop.
+This means you haven't provided the requisite number of arguments for
+this function.  See the documentation of the function for a description
+of its arguments.  @xref{Functions, ,Functions for Transforming Text}.
+
+@item missing target pattern.  Stop.
+@itemx multiple target patterns.  Stop.
+@itemx target pattern contains no `%'.  Stop.
+@itemx mixed implicit and static pattern rules.  Stop.
+These are generated for malformed static pattern rules.  The first means
+there's no pattern in the target section of the rule; the second means
+there are multiple patterns in the target section; the third means
+the target doesn't contain a pattern character (@code{%}); and the
+fourth means that all three parts of the static pattern rule contain
+pattern characters (@code{%})--only the first two parts should.
+@xref{Static Usage, ,Syntax of Static Pattern Rules}.
+
+@item warning: -jN forced in submake: disabling jobserver mode.
+This warning and the next are generated if @code{make} detects error
+conditions related to parallel processing on systems where
+sub-@code{make}s can communicate (@pxref{Options/Recursion,
+,Communicating Options to a Sub-@code{make}}).  This warning is
+generated if a recursive invocation of a @code{make} process is forced
+to have @samp{-j@var{N}} in its argument list (where @var{N} is greater
+than one).  This could happen, for example, if you set the @code{MAKE}
+environment variable to @samp{make -j2}.  In this case, the
+sub-@code{make} doesn't communicate with other @code{make} processes and
+will simply pretend it has two jobs of its own.
+
+@item warning: jobserver unavailable: using -j1.  Add `+' to parent make rule.
+In order for @code{make} processes to communicate, the parent will pass
+information to the child.  Since this could result in problems if the
+child process isn't actually a @code{make}, the parent will only do this
+if it thinks the child is a @code{make}.  The parent uses the normal
+algorithms to determine this (@pxref{MAKE Variable, ,How the @code{MAKE}
+Variable Works}).  If the makefile is constructed such that the parent
+doesn't know the child is a @code{make} process, then the child will
+receive only part of the information necessary.  In this case, the child
+will generate this warning message and proceed with its build in a
+sequential manner.

+@node Complex Makefile, GNU Free Documentation License, Error Messages, Top
+@appendix Complex Makefile Example
+
+Here is the makefile for the GNU @code{tar} program.  This is a
+moderately complex makefile.
+
+Because it is the first target, the default goal is @samp{all}.  An
+interesting feature of this makefile is that @file{testpad.h} is a
+source file automatically created by the @code{testpad} program,
+itself compiled from @file{testpad.c}.
+
+If you type @samp{make} or @samp{make all}, then @code{make} creates
+the @file{tar} executable, the @file{rmt} daemon that provides
+remote tape access, and the @file{tar.info} Info file.
+
+If you type @samp{make install}, then @code{make} not only creates
+@file{tar}, @file{rmt}, and @file{tar.info}, but also installs
+them.
+
+If you type @samp{make clean}, then @code{make} removes the @samp{.o}
+files, and the @file{tar}, @file{rmt}, @file{testpad},
+@file{testpad.h}, and @file{core} files.
+
+If you type @samp{make distclean}, then @code{make} not only removes
+the same files as does @samp{make clean} but also the
+@file{TAGS}, @file{Makefile}, and @file{config.status} files.
+(Although it is not evident, this makefile (and
+@file{config.status}) is generated by the user with the
+@code{configure} program, which is provided in the @code{tar}
+distribution, but is not shown here.)
+
+If you type @samp{make realclean}, then @code{make} removes the same
+files as does @samp{make distclean} and also removes the Info files
+generated from @file{tar.texinfo}.
+
+In addition, there are targets @code{shar} and @code{dist} that create
+distribution kits.

+   KERNEL_FILE			Pathname of the kernel to nlist.
+   LDAV_CVT()			Scale the load average from the kernel.
+				Returns a double.
+   LDAV_SYMBOL			Name of kernel symbol giving load average.

+				Must be defined unless one of
+				apollo, DGUX, NeXT, or UMAX is defined;
+                                or we have libkstat;

+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If `getopt' finds another option character, it returns that character,
+   updating `optind' and `nextchar' so that the next call to `getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, `getopt' returns -1.
+   Then `optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set `opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in `optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in `optarg', otherwise `optarg' is set to zero.
+
+   If OPTSTRING starts with `-' or `+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with `--' instead of `-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a `=', or else the in next ARGV-element.
+   When `getopt' finds a long-named option, it returns 0 if that option's
+   `flag' field is nonzero, the value of the option's `val' field
+   if the `flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of `struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */

+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+                    675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!

+2003-01-30  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.h: Patch for FreeBSD by Mike Barcroft <mike@freebsd.org>
+	Reported by Gerald Pfeifer <pfeifer@dbai.tuwien.ac.at>.  On
+	FreeBSD, declare __size_t to simply size_t.
+
+2002-04-22  Paul D. Smith  <psmith@gnu.org>
+
+	* Makefile.am: Use automake 1.6.
+	Use new automake condition USE_LOCAL_GLOB to decide whether or not
+	to build the local GNU glob library or use the system one.
+
+1999-09-12  Paul D. Smith  <psmith@gnu.org>
+
+	* fnmatch.c: Last GLIBC version wouldn't compile outside of GLIBC
+	(undefined reference to internal_function).  Update to the latest
+	version
+
+1999-09-11  Paul Eggert  <eggert@twinsun.com>
+
+	* glob.h (glob): If #defining to glob64, do this before
+	declaring it, so that all declarations and uses match, and
+	do not declare glob64, to avoid a declaration clash.
+	(globfree): Likewise with globfree64.
+
+1999-09-08  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* glob.c (prefix_array) [__MSDOS__,WINDOWS32]: Keep the trailing
+	slash unless DIRNAME is just "x:/".
+
+1999-09-06  Paul D. Smith  <psmith@gnu.org>
+
+	* fnmatch.c: Update to latest version from GLIBC.
+
+1999-07-21  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.c, glob.h, fnmatch.c, fnmatch.h: Update to latest version
+	from GLIBC.
+
+	* fnmatch.c (internal_fnmatch): Use K&R definition syntax, not ANSI.
+	(__strchrnul): This won't exist outside GLIBC, so create one.
+
+	* glob.c: Move getlogin{,_r} prototypes below glob.h to get __P()
+	macro.
+
+1998-08-05  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Remove; configuration for glob is handled by the
+	make configure.in.
+
+1998-07-29  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.c, fnmatch.c: New versions from the GLIBC folks (Ulrich
+	Drepper).  Fixes a bug reported by Eli Zaretski.  Integrates
+	DOS/Windows32 support.
+
+1998-07-27  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>
+
+	* glob.c (glob): Cast away const on assignment of pattern to dirname.
+	Cast the return type of __alloca() for traditional C compilers.
+
+1998-07-23  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.c, fnmatch.c: New versions of these files from the GLIBC
+	folks (Ulrich Drepper).  Had to re-integrate some DOS/Windows
+	code.
+
+1998-07-10  Paul D. Smith  <psmith@gnu.org>
+
+	* glob.c (glob_in_dir): If no meta chars exist in PATTERN and
+	GLOB_NOCHECK is present, don't look for the file--whether it's
+	found or not, we'll always return it, so why bother searching?
+
+	Also, if we are searching and there are no meta chars, don't
+	bother trying fnmatch() if the strcmp() fails.
+
+1998-05-30  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* glob.c (glob) [__MSDOS__, WINDOWS32]: Compute the directory and
+	filename parts of the pattern correctly when it includes a drive
+	spec.  Disallow wildcards in the drive spec.  Prevent recursion
+	when dirname is of the form "d:/" or "d:".
+	(prefix_array) [__MSDOS__, WINDOWS32]: Don't append a slash to
+	"d:/" and "d:".
+
+1998-05-13  Paul D. Smith  <psmith@gnu.org>
+
+	* SMakefile, Makefile.ami, glob.c, glob.h, fnmatch.c: Updated from
+	the latest glibc version.
+
+1998-04-17  Paul D. Smith  <psmith@gnu.org>
+
+	* configure.in: Create a config.h file instead of setting things
+	on the compile line.  This is because when build.sh runs it merely
+	passes -DHAVE_CONFIG_H to the glob files, just as it does to the
+	make files.
+	* config.h.in: Created by autoheader.
+
+Tue Aug 12 10:52:34 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* configure.in: Require autoconf 2.12.
+
+	* glob: Updates from latest GNU libc glob code.
+
+	* glob.c,glob.h,fnmatch.h: Change all WIN32 references to WINDOWS32.
+
+	* glob.h: OSF4 defines macros in such a way that GLOB_ALTDIRFUNC
+	is not defined.  Added a test to the #if which defines it if
+	_GNU_SOURCE is defined; that's set by both glob.c and GNU make.
+
+	* glob.c: SunOS4 w/ cc needs #include <stdio.h>, since assert.h
+	requires stderr but doesn't include stdio.h :-/.
+	(next_brace_sub): De-protoize function definition.
+	(glob): Cast __alloca(); on SunOS4 it uses the default return type
+	of int.
+	(glob): Irix defines getlogin_r() to return a char*; move the
+	extern for that into the _LIBC area since it isn't used except in
+	LIBC anyway.  Likewise, move extern getlogin() into the "else".
+
+Sat Jul 20 21:55:31 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	Win32 hacks from <Rob_Tulloh@tivoli.com>.
+	* posix/glob.c [WIN32]: Don't include <pwd.h>; don't use d_ino;
+	use void * for my_realloc; include <malloc.h> for alloca.
+	(glob) [WIN32]: Use "c:/users/default" for ~ if no HOME variable.
+	* posix/fnmatch.h [WIN32]: Use prototypes even if [!__STDC__].
+	* posix/glob.h: Likewise.
+
+Fri Jul 19 16:56:41 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	* posix/glob.h [!_AMIGA && !VMS]: Check this instead of just [!_AMIGA]
+	for `struct stat;' forward decl.
+
+Sat Jun 22 10:44:09 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	* posix/glob.c: Include <alloca.h> only [HAVE_ALLOCA_H], not [sparc].
+
+Fri Jun 21 00:27:51 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>
+
+	* posix/fnmatch.c (fnmatch): Fix \*[*?]+ case to increment name ptr
+ 	only for ?s, not for *s.  Fix from Chet Ramey.

+           dup(2) the read FD on the jobserver pipe.  The read(2) call below
+           uses that new FD.  In the signal handler, we close that FD.  That

+ *	Code to make ctrl+c and ctrl+y working.
+ *	The problem starts with the synchronous case where after lib$spawn is
+ *	called any input will go to the child. But with input re-directed,
+ *	both control characters won't make it to any of the programs, neither
+ *	the spawning nor to the spawned one. Hence the caller needs to spawn
+ *	with CLI$M_NOWAIT to NOT give up the input focus. A sys$waitfr
+ *	has to follow to simulate the wanted synchronous behaviour.
+ *	The next problem is ctrl+y which isn't caught by the crtl and
+ *	therefore isn't converted to SIGQUIT (for a signal handler which is
+ *	already established). The only way to catch ctrl+y, is an AST
+ *	assigned to the input channel. But ctrl+y handling of DCL needs to be
+ *	disabled, otherwise it will handle it. Not to mention the previous
+ *	ctrl+y handling of DCL needs to be re-established before make exits.
+ *	One more: At the time of LIB$SPAWN signals are blocked. SIGQUIT will
+ *	make it to the signal handler after the child "normally" terminates.
+ *	This isn't enough. It seems reasonable for simple command lines like
+ *	a 'cc foobar.c' spawned in a subprocess but it is unacceptable for
+ *	spawning make. Therefore we need to abort the process in the AST.
+ *
+ *	Prior to the spawn it is checked if an AST is already set up for
+ *	ctrl+y, if not one is set up for a channel to SYS$COMMAND. In general
+ *	this will work except if make is run in a batch environment, but there
+ *	nobody can press ctrl+y. During the setup the DCL handling of ctrl+y
+ *	is disabled and an exit handler is established to re-enable it.
+ *	If the user interrupts with ctrl+y, the assigned AST will fire, force
+ *	an abort to the subprocess and signal SIGQUIT, which will be caught by
+ *	the already established handler and will bring us back to common code.
+ *	After the spawn (now /nowait) a sys$waitfr simulates the /wait and
+ *	enables the ctrl+y be delivered to this code. And the ctrl+c too,
+ *	which the crtl converts to SIGINT and which is caught by the common
+ *	signal handler. Because signals were blocked before entering this code
+ *	sys$waitfr will always complete and the SIGQUIT will be processed after
+ *	it (after termination of the current block, somewhere in common code).
+ *	And SIGINT too will be delayed. That is ctrl+c can only abort when the
+ *	current command completes. Anyway it's better than nothing :-)

+.TH MAKE 1L "22 August 1989" "GNU" "LOCAL USER COMMANDS"
+.SH NAME
+make \- GNU make utility to maintain groups of programs
+.SH SYNOPSIS
+.B "make "
+[
+.B \-f
+.I makefile
+] [ option ] ...
+target ...
+.SH WARNING
+This man page is an extract of the documentation of
+.I GNU make .
+It is updated only occasionally, because the GNU project does not use nroff.
+For complete, current documentation, refer to the Info file
+.B make.info
+which is made from the Texinfo source file
+.BR make.texinfo .
+.SH DESCRIPTION
+.LP
+The purpose of the
+.I make
+utility is to determine automatically which
+pieces of a large program need to be recompiled, and issue the commands to
+recompile them.
+The manual describes the GNU implementation of
+.IR make ,
+which was written by Richard Stallman and Roland McGrath.
+Our examples show C programs, since they are most common, but you can use
+.I make
+with any programming language whose compiler can be run with a
+shell command.
+In fact,
+.I make
+is not limited to programs.
+You can use it to describe any task where some files must be
+updated automatically from others whenever the others change.
+.LP
+To prepare to use
+.IR make ,
+you must write a file called the
+.I makefile
+that describes the relationships among files in your program, and the
+states the commands for updating each file.
+In a program, typically the executable file is updated from object
+files, which are in turn made by compiling source files.
+.LP
+Once a suitable makefile exists, each time you change some source files,
+this simple shell command:
+.sp 1
+.RS
+.B make
+.RE
+.sp 1
+suffices to perform all necessary recompilations.
+The
+.I make
+program uses the makefile data base and the last-modification times
+of the files to decide which of the files need to be updated.
+For each of those files, it issues the commands recorded in the data base.
+.LP
+.I make
+executes commands in the
+.I makefile
+to update
+one or more target
+.IR names ,
+where
+.I name
+is typically a program.
+If no
+.B \-f
+option is present,
+.I make
+will look for the makefiles
+.IR GNUmakefile ,
+.IR makefile ,
+and
+.IR Makefile ,
+in that order.
+.LP
+Normally you should call your makefile either
+.I makefile
+or
+.IR Makefile .
+(We recommend
+.I Makefile
+because it appears prominently near the beginning of a directory
+listing, right near other important files such as
+.IR  README .)
+The first name checked,
+.IR GNUmakefile ,
+is not recommended for most makefiles.
+You should use this name if you have a makefile that is specific to GNU
+.IR make ,
+and will not be understood by other versions of
+.IR make .
+If
+.I makefile
+is `\-', the standard input is read.
+.LP
+.I make
+updates a target if it depends on prerequisite files
+that have been modified since the target was last modified,
+or if the target does not exist.
+.SH OPTIONS
+.sp 1
+.TP 0.5i
+.B \-b
+.TP 0.5i
+.B \-m
+These options are ignored for compatibility with other versions of
+.IR make .
+.TP 0.5i
+.BI "\-C " dir
+Change to directory
+.I dir
+before reading the makefiles or doing anything else.
+If multiple
+.B \-C
+options are specified, each is interpreted relative to the
+previous one:
+.BR "\-C " /
+.BR "\-C " etc
+is equivalent to
+.BR "\-C " /etc.
+This is typically used with recursive invocations of
+.IR make .
+.TP 0.5i
+.B \-d
+Print debugging information in addition to normal processing.
+The debugging information says which files are being considered for
+remaking, which file-times are being compared and with what results,
+which files actually need to be remade, which implicit rules are
+considered and which are applied---everything interesting about how
+.I make
+decides what to do.
+.TP 0.5i
+.B \-e
+Give variables taken from the environment precedence
+over variables from makefiles.
+.TP 0.5i
+.BI "\-f " file
+Use
+.I file
+as a makefile.
+.TP 0.5i
+.B \-i
+Ignore all errors in commands executed to remake files.
+.TP 0.5i
+.BI "\-I " dir
+Specifies a directory
+.I dir
+to search for included makefiles.
+If several
+.B \-I
+options are used to specify several directories, the directories are
+searched in the order specified.
+Unlike the arguments to other flags of
+.IR make ,
+directories given with
+.B \-I
+flags may come directly after the flag:
+.BI \-I dir
+is allowed, as well as
+.BI "\-I " dir.
+This syntax is allowed for compatibility with the C
+preprocessor's
+.B \-I
+flag.
+.TP 0.5i
+.BI "\-j " jobs
+Specifies the number of jobs (commands) to run simultaneously.
+If there is more than one
+.B \-j
+option, the last one is effective.
+If the
+.B \-j
+option is given without an argument,
+.IR make
+will not limit the number of jobs that can run simultaneously.
+.TP 0.5i
+.B \-k
+Continue as much as possible after an error.
+While the target that failed, and those that depend on it, cannot
+be remade, the other dependencies of these targets can be processed
+all the same.
+.TP 0.5i
+.B \-l
+.TP 0.5i
+.BI "\-l " load
+Specifies that no new jobs (commands) should be started if there are
+others jobs running and the load average is at least
+.I load
+(a floating-point number).
+With no argument, removes a previous load limit.
+.TP 0.5i
+.B \-n
+Print the commands that would be executed, but do not execute them.
+.TP 0.5i
+.BI "\-o " file
+Do not remake the file
+.I file
+even if it is older than its dependencies, and do not remake anything
+on account of changes in
+.IR file .
+Essentially the file is treated as very old and its rules are ignored.
+.TP 0.5i
+.B \-p
+Print the data base (rules and variable values) that results from
+reading the makefiles; then execute as usual or as otherwise
+specified.
+This also prints the version information given by the
+.B \-v
+switch (see below).
+To print the data base without trying to remake any files, use
+.B make
+.B \-p
+.BI \-f /dev/null.
+.TP 0.5i
+.B \-q
+``Question mode''.
+Do not run any commands, or print anything; just return an exit status
+that is zero if the specified targets are already up to date, nonzero
+otherwise.
+.TP 0.5i
+.B \-r
+Eliminate use of the built-in implicit rules.
+Also clear out the default list of suffixes for suffix rules.
+.TP 0.5i
+.B \-s
+Silent operation; do not print the commands as they are executed.
+.TP 0.5i
+.B \-S
+Cancel the effect of the
+.B \-k
+option.
+This is never necessary except in a recursive
+.I make
+where
+.B \-k
+might be inherited from the top-level
+.I make
+via MAKEFLAGS or if you set
+.B \-k
+in MAKEFLAGS in your environment.
+.TP 0.5i
+.B \-t
+Touch files (mark them up to date without really changing them)
+instead of running their commands.
+This is used to pretend that the commands were done, in order to fool
+future invocations of
+.IR make .
+.TP 0.5i
+.B \-v
+Print the version of the
+.I make
+program plus a copyright, a list of authors and a notice that there
+is no warranty.
+.TP 0.5i
+.B \-w
+Print a message containing the working directory
+before and after other processing.
+This may be useful for tracking down errors from complicated nests of
+recursive
+.I make
+commands.
+.TP 0.5i
+.BI "\-W " file
+Pretend that the target
+.I file
+has just been modified.
+When used with the
+.B \-n
+flag, this shows you what would happen if you were to modify that file.
+Without
+.BR \-n ,
+it is almost the same as running a
+.I touch
+command on the given file before running
+.IR make ,
+except that the modification time is changed only in the imagination of
+.IR make .

+This is the VMS port of GNU Make done by Hartmut.Becker@compaq.com.
+
+It is based on the specific version 3.77k and on 3.78.1. 3.77k was done
+by Klaus Kämpf <kkaempf@rmi.de>, the code was based on the VMS port of
+GNU Make 3.60 by Mike Moretti.
+
+It was ported on OpenVMS/Alpha V7.1, DECC V5.7-006. It was re-build and
+tested on OpenVMS/Alpha V7.2, OpenVMS/VAX 7.1 and 5.5-2. Different
+versions of DECC were used. VAXC was tried: it fails; but it doesn't
+seem worth to get it working. There are still some PTRMISMATCH warnings
+during the compile. Although perl is working on VMS the test scripts
+don't work. The function $shell is still missing.
+
+There is a known bug in some of the VMS CRTLs. It is in the shipped
+versions of VMS V7.2 and V7.2-1 and in the currently (October 1999)
+available ECOs for VMS V7.1 and newer versions. It is fixed in versions
+shipped with newer VMS versions and all ECO kits after October 1999. It
+only shows up during the daylight saving time period (DST): stat()
+returns a modification time 1 hour ahead. This results in GNU make
+warning messages. For a just created source you will see:
+
+ $ gmake x.exe
+ gmake.exe;1: *** Warning: File `x.c' has modification time in the future (940582863 > 940579269)
+ cc    /obj=x.obj x.c
+ link  x.obj    /exe=x.exe
+ gmake.exe;1: *** Warning:  Clock skew detected.  Your build may be incomplete.
+
+
+New in 3.78.1:
+
+Fix a problem with automatically remaking makefiles. GNU make uses an
+execve to restart itself after a successful remake of the makefile. On
+UNIX systems execve replaces the running program with a new one and
+resets all signal handling to the default. On VMS execve creates a child
+process, signal and exit handlers of the parent are still active, and,
+unfortunately, corrupt the exit code from the child. Fix in job.c:
+ignore SIGCHLD.
+
+Added some switches to reflect latest features of DECC. Modifications in
+makefile.vms.
+
+Set some definitions to reflect latest features of DECC. Modifications in
+config.h-vms (which is copied to config.h).
+
+Added extern strcmpi declaration to avoid 'implicitly declared' messages.
+Modification in make.h.
+
+Default rule for C++, conditionals for gcc (GCC_IS_NATIVE) or DEC/Digital/
+Compaq c/c++ compilers. Modifications in default.c.
+
+Usage of opendir() and friends, suppress file version. Modifications in dir.c.
+
+Added VMS specific code to handle ctrl+c and ctrl+y to abort make.
+Modifications in job.c.
+
+Added support to have case sensitive targets and dependencies but to
+still use case blind file names. This is especially useful for Java
+makefiles on VMS:
+
+	.SUFFIXES :
+	.SUFFIXES :	.class .java
+	.java.class :
+		javac "$<
+	HelloWorld.class :      HelloWorld.java
+
+A new macro WANT_CASE_SENSITIVE_TARGETS in config.h-vms was introduced.
+It needs to be enabled to get this feature; default is disabled.  The
+macro HAVE_CASE_INSENSITIVE_FS must not be touched: it is still enabled.
+Modifications in file.c and config.h-vms.
+
+Bootstrap make to start building make is still makefile.com, but make
+needs to be re-made with a make to make a correct version: ignore all
+possible warnings, delete all objects, rename make.exe to a different
+name and run it.
+
+Made some minor modifications to the bootstrap build makefile.com.
+
+
+This is the VMS port of GNU Make.
+
+It is based on the VMS port of GNU Make 3.60 by Mike Moretti.
+
+This port was done by Klaus Kämpf <kkaempf@rmi.de>
+
+There is first-level support available from proGIS Software, Germany.
+Visit their web-site at http://www.progis.de to get information
+about other vms software and forthcoming updates to gnu make.
+
+New for 3.77:
+
+/bin/sh style I/O redirection is supported. You can now write lines like
+	mcr sys$disk:[]program.exe < input.txt > output.txt &> error.txt
+
+Makefile variables are looked up in the current environment. You can set
+symbols or logicals in DCL and evaluate them in the Makefile via
+$(<name-of-symbol-or-logical>).  Variables defined in the Makefile
+override VMS symbols/logicals !
+
+Functions for file names are working now. See the GNU Make manual for
+$(dir ...)  and $(wildcard ...).  Unix-style and VMS-style names are
+supported as arguments.
+
+The default rules are set up for GNU C. Building an executable from a
+single source file is as easy as 'make file.exe'.
+
+The variable $(ARCH) is predefined as ALPHA or VAX resp. Makefiles for
+different VMS systems can now be written by checking $(ARCH) as in
+  ifeq ($(ARCH),ALPHA)
+    $(ECHO) "On the Alpha"
+  else
+    $(ECHO) "On the VAX"
+  endif
+
+Command lines of excessive length are correctly broken and written to a
+batch file in sys$scratch for later execution. There's no limit to the
+lengths of commands (and no need for .opt files :-) any more.
+
+Empty commands are handled correctly and don't end in a new DCL process.
+
+
+New for 3.76:
+
+John W. Eaton has updated the VMS port to support libraries and VPATH.
+
+
+To build Make, simply type @makefile.  This should compile all the
+necessary files and link Make.  There is also a file called
+makefile.vms.  If you already have GNU Make built you can just use
+Make with this makefile to rebuild.
+
+Here are some notes about GNU Make for VMS:
+
+The cd command is supported if it's called as $(CD). This invokes
+the 'builtin_cd' command which changes the directory.
+Calling 'set def' doesn't do the trick, since a sub-shell is
+spawned for this command, the directory is changed *in this sub-shell*
+and the sub-shell ends.
+
+Libraries are not supported. They were in GNU Make 3.60 but somehow I
+didn't care porting the code. If there is enough interest, I'll do it at
+some later time.
+
+The variable $^ separates files with commas instead of spaces (It's the
+natural thing to do for VMS).
+
+See defaults.c for VMS default suffixes and my definitions for default
+rules and variables.
+
+The shell function is not implemented yet.
+
+Load average routines haven't been implemented for VMS yet.
+
+The default include directory for including other makefiles is
+SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use
+SYS$LIBRARY: instead; maybe it wouldn't work that way).
+
+The default makefiles make looks for are: makefile.vms, gnumakefile,
+makefile., and gnumakefile. .
+
+The stat() function and handling of time stamps in VMS is broken, so I
+replaced it with a hack in vmsfunctions.c. I will provide a full rewrite
+somewhere in the future. Be warned, the time resolution inside make is
+less than what vms provides. This might be a problem on the faster Alphas.
+
+You can use a : in a filename only if you preceed it with a backslash ('\').
+E.g.- hobbes\:[bogas.files]
+
+Make ignores success, informational, or warning errors (-S-, -I-, or
+-W-).  But it will stop on -E- and -F- errors. (unless you do something
+to override this in your makefile, or whatever).
+
+Remote stuff isn't implemented yet.
+
+Multiple line DCL commands, such as "if" statements, must be put inside
+command files.  You can run a command file by using \@.
+
+
+VMS changes made for 3.74.3
+
+Lots of default settings are adapted for VMS. See default.c.
+
+Long command lines are now converted to command files.
+
+Comma (',') as a separator is now allowed. See makefile.vms for an example.

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+2000-06-15  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* scripts/options/general: Don't try -jN with N != 1 if parallel

+2000-04-11  Paul D. Smith  <psmith@gnu.org>
+
+	* scripts/functions/strip: Test empty value to strip (PR/1689).
+
+2000-04-08  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* scripts/features/reinvoke: Sleep before updating the target
+	files in the first test, to ensure its time stamp really gets
+	newer; otherwise Make might re-exec more than once.
+
+2000-04-07  Eli Zaretskii  <eliz@is.elta.co.il>
+
+	* scripts/features/double_colon: Don't run the parallel tests if
+	parallel jobs aren't supported.
+
+2000-04-04  Paul D. Smith  <psmith@gnu.org>
+
+	* scripts/functions/word: wordlist doesn't swap arguments anymore.
+
+2000-03-27  Paul D. Smith  <psmith@gnu.org>
+
+	* scripts/features/statipattrules: Test that static pattern rules
+	whose prerequisite patterns resolve to empty strings throw an
+	error (instead of dumping core).  Fixes PR/1670.
+
+	* scripts/features/reinvoke: Make more robust by touching "b"
+	first, to ensure it's not newer than "a".
+	Reported by Marco Franzen <Marco.Franzen@Thyron.com>.
+	* scripts/options/dash-n: Ditto.
+
+	* scripts/functions/call: Whoops.  The fix to PR/1527 caused
+	recursive invocations of $(call ...) to break.  I can't come up
+	with any way to get both working at the same time, so I backed out
+	the fix to 1527 and added a test case for recursive calls.  This
+	also tests the fix for PR/1610.
+
+	* scripts/features/double_colon: Test that circular dependencies
+	in double-colon rule sets are detected correctly (PR/1671).
+

+
+	* scripts/features/reinvoke: Remove invocations of "touch" in
+	makefiles.  See the comments on the touch function rewrite below.
+	Note that UNIX touch behaves the same way if the file already
+	exists: it sets the time to the _local_ time.  We don't want

+	general, actually... where practical.
+	* scripts/options/dash-l: Ditto.
+	* scripts/options/dash-n: Ditto.
+
+	* test_driver.pl (run_each_test): In retrospect, I don't like the
+	.lN/.bN/.dN postfix required by DOS.  So, for non-DOS systems I
+	changed it back to use .log, .base, and .diff.
+
+	* run_make_tests.pl (set_more_defaults): Move the check for the
+	make pathname to here from set_defaults (that's too early since it
+	happens before the command line processing).
+	Create a new variable $port_type, calculated from $osname, to
+	specify what kind of system we're running on.  We should integrate
+	the VOS stuff here, too.
+	(valid_option): Comment out the workdir/-work stuff so people
+	won't be fooled into thinking it works... someone needs to fix
+	this, though!
+
+	* scripts/functions/origin: Use $port_type instead of $osname.
+	* scripts/functions/foreach: Ditto.
+	* scripts/features/default_names: Ditto.
+
+1999-09-15  Paul D. Smith  <psmith@gnu.org>
+
+	* test_driver.pl (touch): Rewrite this function.  Previously it
+	used to use utime() to hard-set the time based on the current
+	local clock, or, if the file didn't exist, it merely created it.
+	This mirrors exactly what real UNIX touch does, but it fails badly
+	on networked filesystems where the FS server clock is skewed from
+	the local clock: normally modifying a file causes it to get a mod
+	time based on the _server's_ clock.  Hard-setting it based on the
+	_local_ clock causes gratuitous errors and makes the tests
+	unreliable except on local filesystems.  The new function will
+	simply modify the file, allowing the filesystem to set the mod
+	time as it sees fit.
+
+	* scripts/features/parallelism: The second test output could
+	change depending on how fast some scripts completed; use "sleep"
+	to force the order we want.
+
+	* test_driver.pl (toplevel): A bug in Perl 5.000 to Perl 5.004
+	means that "%ENV = ();" doesn't do the right thing.  This worked
+	in Perl 4 and was fixed in Perl 5.004_01, but use a loop to delete
+	the environment rather than require specific versions.
+
+	* run_make_tests.pl (set_more_defaults): Don't use Perl 5 s///
+	modifier "s", so the tests will run with Perl 4.
+	(set_more_defaults): Set $pure_log to empty if there's no -logfile
+	option in PURIFYOPTIONS.
+	(setup_for_test): Don't remove any logs unless $pure_log is set.
+

+Changes from 0.4.9 to 3.78 (Sep 6, 1999):
+
+    Lots of new tests.  Renamed to follow the GNU make scheme.  Also
+    added some support for using Purify with make.
+
+    Rob Tulloh contributed some changes to get the test suite running on
+    NT; I tweaked them a bit (hopefully I didn't break anything!)  Note
+    that NT doesn't grok the self-exec funkiness that Unix shells use,
+    so instead I broke that out into a separate shell script
+    "run_make_tests" that invokes perl with the (renamed) script
+    run_make_tests.pl.
+
+    Eli Zaretski contributed changes to get the test suite running on
+    DOS with DJGPP.  I also meddled in these somewhat.
+
+    If you're on DOS or NT you should run "perl.exe run_make_tests.pl ..."
+    If you're on Unix, you can continue to run "./run_make_tests ..." as
+    before.
+
+Changes from 0.4.8 to 0.4.9 (May 14, 1998):
+
+    Release by Paul D. Smith <psmith@baynetworks.com>; I'm the one to
+    blame for problems in this version :).
+
+    Add some perl to test_driver.pl to strip out GNU make clock skew
+    warning messages from the output before comparing it to the
+    known-good output.
+
+    A new test for escaped :'s in filenames (someone on VMS found this
+    didn't work anymore in 3.77): scripts/features/escape.
+
+Changes from 0.4.7 to 0.4.8 (May 14, 1998):
+
+    Release by Paul D. Smith <psmith@baynetworks.com>; I'm the one to
+    blame for problems in this version :).
+
+    New tests for features to be included in GNU make 3.77.
+
+Changes from 0.4.6 to 0.4.7 (August 18, 1997):
+
+    Release by Paul D. Smith <psmith@baynetworks.com>; I'm the one to
+    blame for problems in this version :).
+
+    Reworked some tests to make sure they all work with both perl4 and perl5.
+
+    Work around a bug in perl 5.004 which doesn't clean the environment
+    correctly in all cases (fixed in at least 5.004_02).
+
+    Updated functions/strip to test for newline stripping.
+
+    Keep a $PURIFYOPTIONS env variable if present.
+
+Changes from 0.4.5 to 0.4.6 (April 07, 1997):
+
+    Release by Paul D. Smith <psmith@baynetworks.com>; I'm the one to
+    blame for problems in this version :).
+
+    Updated to work with GNU make 3.76 (and pretests).
+
+    Added new tests and updated existing ones.  Note that the new tests
+    weren't tested with perl 4, however I think they should work.
+
+    Ignore any tests whose filenames end in "~", so that Emacs backup
+    files aren't run.
+
+Changes from 0.4.4 to 0.4.5 (April 29, 1995):
+
+    Updated to be compatible with perl 5.001 as well as 4.036.
+
+    Note: the test suite still won't work on 14-char filesystems
+    (sorry, Kaveh), but I will get to it.
+
+    Also, some tests and stuff still haven't made it in because I
+    haven't had time to write the test scripts for them.  But they,
+    too, will get in eventually.  Contributions of scripts (ie, tests
+    that I can just drop in) are particularly welcome and will be
+    incorporated immediately.
+
+Changes from 0.4.3 to 0.4.4 (March 1995):
+
+    Updated for changes in make 3.72.12, and to ignore CVS directories
+    (thanks go to Jim Meyering for the patches for this).
+
+    Fixed uname call to not make a mess on BSD/OS 2.0 (whose uname -a
+    is very verbose).  Let me know if this doesn't work correctly on
+    your system.
+
+    Changed to display test name while it is running, not just when it
+    finishes.
+
+    Note: the test suite still won't work on 14-char filesystems
+    (sorry, Kaveh), but I will get to it.
+
+    Also, some tests and stuff still haven't made it in because I
+    haven't had time to write the test scripts for them.  But they,
+    too, will get in eventually.
+
+Changes from 0.4 to 0.4.3 (October 1994):
+
+    Fixed bugs (like dependencies on environment variables).
+
+    Caught up with changes in make.
+
+    The load_limit test should now silently ignore a failure due to
+    make not being able to read /dev/kmem.
+
+    Reorganized tests into subdirs and renamed lots of things so that
+    those poor souls who still have to deal with 14-char filename
+    limits won't hate me any more.  Thanks very much to Kaveh R. Ghazi
+    <ghazi@noc.rutgers.edu> for helping me with the implementation and
+    testing of these changes, and for putting up with all my whining
+    about it...
+
+    Added a $| = 1 so that systems that don't seem to automatically
+    flush their output for some reason will still print all the
+    output.  I'd hate for someone to miss out on the smiley that
+    you're supposed to get when all the tests pass... :-)
+
+Changes from 0.3 to 0.4 (August 1993):
+
+    Lost in the mists of time (and my hurry to get it out before I
+    left my job).
+
+Changes from 0.2 to 0.3 (9-30-92):
+
+    Several tests fixed to match the fact that MAKELEVEL > 0 or -C now
+    imply -w.
+
+    parallel_execution test fixed to not use double colon rules any
+    more since their behavior has changed.
+
+    errors_in_commands test fixed to handle different error messages
+    and return codes from rm.
+
+    Several tests fixed to handle -make_path with a relative path
+    and/or a name other than "make" for make.
+
+    dash-e-option test fixed to use $PATH instead of $USER (since the
+    latter does not exist on some System V systems).  This also
+    removes the dependency on getlogin (which fails under certain
+    weird conditions).
+
+    test_driver_core changed so that you can give a test name like
+    scripts/errors_in_commands and it will be handled correctly (handy
+    if you have a shell with filename completion).
+
+Changes from 0.1 to 0.2 (5-4-92):
+
+    README corrected to require perl 4.019, not 4.010.
+
+    -make_path replaces -old.
+
+    errors_in_commands test updated for change in format introduced in
+    make 3.62.6.
+
+    test_driver_core now uses a better way of figuring what OS it is
+    running on (thanks to meyering@cs.utexas.edu (Jim Meyering) for
+    suggesting this, as well as discovering the hard way that the old
+    way (testing for /mnt) fails on his machine).
+
+    Some new tests were added.

+This is release 3.78 (September 6, 1999) of the GNU make test
+suite.  See the file NEWS for some of the changes since the last
+release.
+
+This release is made by psmith@gnu.org to correspond to GNU make 3.78.
+It won't work correctly for versions before that.  In addition to some
+infrastructure changes I've added a number of new tests.
+
+Rob Tulloh has contributed changes to get the suite running on NT.
+
+Eli Zaretskii and Esa A E Peuha <peuha@cc.helsinki.fi> have contributed
+changes to get the suite running on DJGPP/DOS.
+
+This package has a number of problems which preclude me from
+distributing it with make as a default "make check" test suite.  The
+most serious of these is that it's not parallelizable: it scribbles all
+over its installation directory and so can only test one make at a
+time.  I simply don't have time to do more with this than I am so far;
+I'm very actively interested in finding someone willing to overhaul the
+test suite infrastructure.  If you're interested, contact me (see below)!
+
+The test suite thus far has been written by Steve McGee, Chris Arthur,
+and Paul D. Smith.  It is covered by the GNU General Public License
+(Version 2), described in the file COPYING.
+
+The test suite requires Perl and is known to work with Perl 4.036 and
+Perl 5.004 (available from ftp.gnu.org, and portable to many machines).
+Earlier or later versions may work; I don't know.  It assumes that the
+first "diff" it finds is GNU diff, but that only matters if a test
+fails.
+
+To run the test suite on a UNIX system, use "perl ./run_make_tests"
+(or just "./run_make_tests" if you have a perl on your PATH).
+
+To run the test suite on Windows NT or DOS systems, use
+"perl.exe ./run_make-tests.pl".
+
+By default, the test engine picks up the first executable called "make"
+that it finds in your path.  You may use the -make_path option (ie,
+"perl run_make_tests -make_path /usr/local/src/make-3.78/make") if
+you want to run a particular copy.  This now works correctly with
+relative paths and when make is called something other than "make" (like
+"gmake").
+
+Tests cannot end with a "~" character, as the test suite will ignore any
+that do (I was tired of having it run my Emacs backup files as test :)
+
+If you want to run the tests in parallel, you should use the mkshadow
+script included here to create temporary "copies" (via symbolic links)
+of the test suite, one for each parallel job.  This is a pain and one
+day maybe the test suite will be rewritten so it's no longer
+necessary--volunteers welcome!
+
+Also, sometimes the tests may behave strangely on networked
+filesystems.  You can use mkshadow to create a copy of the test suite in
+/tmp or similar, and try again.  If the error disappears, it's an issue
+with your network or file server, not GNU make (I believe).
+
+The options/dash-l test will not really test anything if the copy of
+make you are using can't obtain the system load.  Some systems require
+make to be setgid sys or kmem for this; if you don't want to install
+make just to test it, make it setgid to kmem or whatever group /dev/kmem
+is (ie, "chgrp kmem make;chmod g+s make" as root).  In any case, the
+options/dash-l test should no longer *fail* because make can't read
+/dev/kmem.
+
+A directory named "work" will be created when the tests are run which
+will contain any makefiles and "diff" files of tests that fail so that
+you may look at them afterward to see the output of make and the
+expected result.
+
+There is a -help option which will give you more information about the
+other possible options for the test suite.
+
+Any complaints/suggestions/bugs/etc. for the test suite itself (as
+opposed to problems in make that the suite finds) should be sent to
+psmith@gnu.org.  Enjoy!
+                                                Paul D. Smith
