6336	# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
6337	# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
6338	# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
6339	#
6340	# Of course, Automake must honor this variable whenever it calls a
6341	# tool from the auxiliary directory. The problem is that $srcdir (and
6342	# therefore $ac_aux_dir as well) can be either absolute or relative,
6343	# depending on how configure is run. This is pretty annoying, since
6344	# it makes $ac_aux_dir quite unusable in subdirectories: in the top
6345	# source directory, any form will work fine, but in subdirectories a
6346	# relative path needs to be adjusted first.
6347	#
6348	# $ac_aux_dir/missing
6349	# fails when called from a subdirectory if $ac_aux_dir is relative
6350	# $top_srcdir/$ac_aux_dir/missing
6351	# fails if $ac_aux_dir is absolute,
6352	# fails when called from a subdirectory in a VPATH build with
6353	# a relative $ac_aux_dir
6354	#
6355	# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
6356	# are both prefixed by $srcdir. In an in-source build this is usually
6357	# harmless because $srcdir is `.', but things will broke when you
6358	# start a VPATH build or use an absolute $srcdir.
6359	#
6360	# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
6361	# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
6362	# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//\(.\)"`
6363	# and then we would define $MISSING as
6364	# MISSING="\${SHELL} $am_aux_dir/missing"
6365	# This will work as long as MISSING is not called from configure, because
6366	# unfortunately $(top_srcdir) has no meaning in configure.
6367	# However there are other variables, like CC, which are often used in
6368	# configure, and could therefore not use this "fixed" $ac_aux_dir.
6369	#
6370	# Another solution, used here, is to always expand $ac_aux_dir to an
6371	# absolute PATH. The drawback is that using absolute paths prevent a
6372	# configured tree to be moved without reconfiguration.
