283	# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
284	# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
285	#
286	# Of course, Automake must honor this variable whenever it calls a
287	# tool from the auxiliary directory. The problem is that $srcdir (and
288	# therefore $ac_aux_dir as well) can be either absolute or relative,
289	# depending on how configure is run. This is pretty annoying, since
290	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
291	# source directory, any form will work fine, but in subdirectories a
292	# relative path needs to be adjusted first.
293	#
294	# $ac_aux_dir/missing
295	# fails when called from a subdirectory if $ac_aux_dir is relative
296	# $top_srcdir/$ac_aux_dir/missing
297	# fails if $ac_aux_dir is absolute,
298	# fails when called from a subdirectory in a VPATH build with
299	# a relative $ac_aux_dir
300	#
301	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
302	# are both prefixed by $srcdir. In an in-source build this is usually
303	# harmless because $srcdir is '.', but things will broke when you
304	# start a VPATH build or use an absolute $srcdir.
305	#
306	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
307	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
308	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//$.$"`
309	# and then we would define $MISSING as
310	# MISSING="\${SHELL} $am_aux_dir/missing"
311	# This will work as long as MISSING is not called from configure, because
312	# unfortunately $(top_srcdir) has no meaning in configure.
313	# However there are other variables, like CC, which are often used in
314	# configure, and could therefore not use this "fixed" $ac_aux_dir.
315	#
316	# Another solution, used here, is to always expand $ac_aux_dir to an
