6465	# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6466	# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
6467	# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6468	#
6469	# Of course, Automake must honor this variable whenever it calls a
6470	# tool from the auxiliary directory. The problem is that $srcdir (and
6471	# therefore $ac_aux_dir as well) can be either absolute or relative,
6472	# depending on how configure is run. This is pretty annoying, since
6473	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
6474	# source directory, any form will work fine, but in subdirectories a
6475	# relative path needs to be adjusted first.
6476	#
6477	# $ac_aux_dir/missing
6478	# fails when called from a subdirectory if $ac_aux_dir is relative
6479	# $top_srcdir/$ac_aux_dir/missing
6480	# fails if $ac_aux_dir is absolute,
6481	# fails when called from a subdirectory in a VPATH build with
6482	# a relative $ac_aux_dir
6483	#
6484	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6485	# are both prefixed by $srcdir. In an in-source build this is usually
6486	# harmless because $srcdir is `.', but things will broke when you
6487	# start a VPATH build or use an absolute $srcdir.
6488	#
6489	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6490	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
6491	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//$.$"`
6492	# and then we would define $MISSING as
6493	# MISSING="\${SHELL} $am_aux_dir/missing"
6494	# This will work as long as MISSING is not called from configure, because
6495	# unfortunately $(top_srcdir) has no meaning in configure.
6496	# However there are other variables, like CC, which are often used in
6497	# configure, and could therefore not use this "fixed" $ac_aux_dir.
6498	#
6499	# Another solution, used here, is to always expand $ac_aux_dir to an
