# The logic here is partly dictated by the desire to keep the lib?77
# subdirs for compatibility with the Netlib version and because libU77
# has a different copyright; then the libe77 bit (EXTERNALly-callable
# versions) is funny.  Given that, as well as keeping things as simple
# as possible we want (at least) the following:
#  * Allow make to be run at the top level (all-target-libf2c), at this
#    level, or the subdirs of this level.  In the latter case we only
#    compile, rather than updating libg2c.a;
#  * A robust set of dependencies, so that we rebuild (as little as
#    possible) if a configuration file, g2c.h or any lib?77/*.c file
#    changes;
#  * Avoid unnecessary running of ar and ranlib;
#  * Expose parallelism where reasonable, but not as a priority.

# The intended top-level target here does a non-multilib build (via
# the dependency) and then (perhaps) builds multilibs.

# `all-unilib' is the overall target in the absence of multilibs,
# meant to be invoked via multi-do for multilibs.

# Its dependencies can be satisfied in parallel.  The [fiu]77 targets
# update stamp files (object file lists, actually, see the subdir
# makefiles) on which the $(LIBG2C) depends.  The stamp files
# s-lib[fiu]77 are intentionally not targets, since we're only meant
# to come in at the level of this target.  The [fiu]77 targets always
# invoke sub makes to check dependencies in the subdirs, else we'd
# have to maintain them at this level; we live with the overhead of
# some recursive makes which may do nothing.
