d7639a	230	#
SP	231	# Of course, Automake must honor this variable whenever it calls a
	232	# tool from the auxiliary directory. The problem is that $srcdir (and
	233	# therefore $ac_aux_dir as well) can be either absolute or relative,
	234	# depending on how configure is run. This is pretty annoying, since
	235	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
	236	# source directory, any form will work fine, but in subdirectories a
	237	# relative path needs to be adjusted first.

	241	# $top_srcdir/$ac_aux_dir/missing

	243	# fails when called from a subdirectory in a VPATH build with
	244	# a relative $ac_aux_dir
	245	#
	246	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
	247	# are both prefixed by $srcdir. In an in-source build this is usually
a00f10	248	# harmless because $srcdir is '.', but things will broke when you
d7639a	249	# start a VPATH build or use an absolute $srcdir.
SP	250	#
	251	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
	252	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
	253	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//$.$"`
	254	# and then we would define $MISSING as
	255	# MISSING="\${SHELL} $am_aux_dir/missing"

	258	# However there are other variables, like CC, which are often used in
	259	# configure, and could therefore not use this "fixed" $ac_aux_dir.
	260	#
	261	# Another solution, used here, is to always expand $ac_aux_dir to an
