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