	70	# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
	71	# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
	72	# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
	73	#
	74	# Of course, Automake must honor this variable whenever it calls a
	75	# tool from the auxiliary directory. The problem is that $srcdir (and
	76	# therefore $ac_aux_dir as well) can be either absolute or relative,
	77	# depending on how configure is run. This is pretty annoying, since
	78	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
	79	# source directory, any form will work fine, but in subdirectories a
	80	# relative path needs to be adjusted first.
	81	#
	82	# $ac_aux_dir/missing
	83	# fails when called from a subdirectory if $ac_aux_dir is relative
	84	# $top_srcdir/$ac_aux_dir/missing
	85	# fails if $ac_aux_dir is absolute,
	86	# fails when called from a subdirectory in a VPATH build with
	87	# a relative $ac_aux_dir
	88	#
	89	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
	90	# are both prefixed by $srcdir. In an in-source build this is usually
	91	# harmless because $srcdir is '.', but things will broke when you
	92	# start a VPATH build or use an absolute $srcdir.
	93	#
	94	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
	95	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
	96	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//$.$"`
	97	# and then we would define $MISSING as
	98	# MISSING="\${SHELL} $am_aux_dir/missing"
	99	# This will work as long as MISSING is not called from configure, because
	100	# unfortunately $(top_srcdir) has no meaning in configure.
	101	# However there are other variables, like CC, which are often used in
	102	# configure, and could therefore not use this "fixed" $ac_aux_dir.
	103	#
	104	# Another solution, used here, is to always expand $ac_aux_dir to an
	105	# absolute PATH. The drawback is that using absolute paths prevent a
	106	# configured tree to be moved without reconfiguration.
