6645	# fails when called from a subdirectory in a VPATH build with

6647	#
6648	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6649	# are both prefixed by $srcdir. In an in-source build this is usually
6650	# harmless because $srcdir is `.', but things will broke when you
6651	# start a VPATH build or use an absolute $srcdir.
6652	#
6653	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6654	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
6655	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//$.$"`
6656	# and then we would define $MISSING as
6657	# MISSING="\${SHELL} $am_aux_dir/missing"

6659	# unfortunately $(top_srcdir) has no meaning in configure.
6660	# However there are other variables, like CC, which are often used in
6661	# configure, and could therefore not use this "fixed" $ac_aux_dir.
6662	#
6663	# Another solution, used here, is to always expand $ac_aux_dir to an
6664	# absolute PATH. The drawback is that using absolute paths prevent a
