1195	# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
1196	#
1197	# Of course, Automake must honor this variable whenever it calls a
1198	# tool from the auxiliary directory. The problem is that $srcdir (and
1199	# therefore $ac_aux_dir as well) can be either absolute or relative,
1200	# depending on how configure is run. This is pretty annoying, since
1201	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
1202	# source directory, any form will work fine, but in subdirectories a
1203	# relative path needs to be adjusted first.
1204	#
1205	# $ac_aux_dir/missing
1206	# fails when called from a subdirectory if $ac_aux_dir is relative
1207	# $top_srcdir/$ac_aux_dir/missing
1208	# fails if $ac_aux_dir is absolute,
1209	# fails when called from a subdirectory in a VPATH build with
1210	# a relative $ac_aux_dir
1211	#
1212	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1213	# are both prefixed by $srcdir. In an in-source build this is usually
1214	# harmless because $srcdir is `.', but things will broke when you
1215	# start a VPATH build or use an absolute $srcdir.
1216	#
1217	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1218	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
1219	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//\(.\)"`
1220	# and then we would define $MISSING as
1221	# MISSING="\${SHELL} $am_aux_dir/missing"
1222	# This will work as long as MISSING is not called from configure, because
1223	# unfortunately $(top_srcdir) has no meaning in configure.
1224	# However there are other variables, like CC, which are often used in
1225	# configure, and could therefore not use this "fixed" $ac_aux_dir.
1226	#
1227	# Another solution, used here, is to always expand $ac_aux_dir to an
1228	# absolute PATH. The drawback is that using absolute paths prevent a
