871	# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

873	# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
874	#
875	# Of course, Automake must honor this variable whenever it calls a
876	# tool from the auxiliary directory. The problem is that $srcdir (and
877	# therefore $ac_aux_dir as well) can be either absolute or relative,
878	# depending on how configure is run. This is pretty annoying, since
879	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
880	# source directory, any form will work fine, but in subdirectories a
881	# relative path needs to be adjusted first.
882	#
883	# $ac_aux_dir/missing
884	# fails when called from a subdirectory if $ac_aux_dir is relative
885	# $top_srcdir/$ac_aux_dir/missing
886	# fails if $ac_aux_dir is absolute,
887	# fails when called from a subdirectory in a VPATH build with
888	# a relative $ac_aux_dir
889	#
890	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
891	# are both prefixed by $srcdir. In an in-source build this is usually
892	# harmless because $srcdir is `.', but things will broke when you
893	# start a VPATH build or use an absolute $srcdir.
894	#
895	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
896	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
897	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//$.$"`
898	# and then we would define $MISSING as
899	# MISSING="\${SHELL} $am_aux_dir/missing"
900	# This will work as long as MISSING is not called from configure, because
901	# unfortunately $(top_srcdir) has no meaning in configure.
902	# However there are other variables, like CC, which are often used in
903	# configure, and could therefore not use this "fixed" $ac_aux_dir.
904	#
905	# Another solution, used here, is to always expand $ac_aux_dir to an
906	# absolute PATH. The drawback is that using absolute paths prevent a
