41	# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
42	# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
43	# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
44	#
45	# Of course, Automake must honor this variable whenever it calls a
46	# tool from the auxiliary directory. The problem is that $srcdir (and
47	# therefore $ac_aux_dir as well) can be either absolute or relative,
48	# depending on how configure is run. This is pretty annoying, since
49	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
50	# source directory, any form will work fine, but in subdirectories a
51	# relative path needs to be adjusted first.
52	#
53	# $ac_aux_dir/missing
54	# fails when called from a subdirectory if $ac_aux_dir is relative
55	# $top_srcdir/$ac_aux_dir/missing
56	# fails if $ac_aux_dir is absolute,
57	# fails when called from a subdirectory in a VPATH build with
58	# a relative $ac_aux_dir
59	#
60	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
61	# are both prefixed by $srcdir. In an in-source build this is usually
62	# harmless because $srcdir is `.', but things will broke when you
63	# start a VPATH build or use an absolute $srcdir.
64	#
65	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
66	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
67	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//$.$"`
68	# and then we would define $MISSING as
69	# MISSING="\${SHELL} $am_aux_dir/missing"
70	# This will work as long as MISSING is not called from configure, because
71	# unfortunately $(top_srcdir) has no meaning in configure.
72	# However there are other variables, like CC, which are often used in
73	# configure, and could therefore not use this "fixed" $ac_aux_dir.
74	#
75	# Another solution, used here, is to always expand $ac_aux_dir to an
76	# absolute PATH. The drawback is that using absolute paths prevent a
77	# configured tree to be moved without reconfiguration.
