808# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
809# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
810# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
811#
812# Of course, Automake must honor this variable whenever it calls a
813# tool from the auxiliary directory.  The problem is that $srcdir (and
814# therefore $ac_aux_dir as well) can be either absolute or relative,
815# depending on how configure is run.  This is pretty annoying, since
816# it makes $ac_aux_dir quite unusable in subdirectories: in the top
817# source directory, any form will work fine, but in subdirectories a
818# relative path needs to be adjusted first.
819#
820# $ac_aux_dir/missing
821#    fails when called from a subdirectory if $ac_aux_dir is relative
822# $top_srcdir/$ac_aux_dir/missing
823#    fails if $ac_aux_dir is absolute,
824#    fails when called from a subdirectory in a VPATH build with
825#          a relative $ac_aux_dir
826#
827# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
828# are both prefixed by $srcdir.  In an in-source build this is usually
829# harmless because $srcdir is '.', but things will broke when you
830# start a VPATH build or use an absolute $srcdir.
831#
832# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
833# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
834#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
835# and then we would define $MISSING as
836#   MISSING="\${SHELL} $am_aux_dir/missing"
837# This will work as long as MISSING is not called from configure, because
838# unfortunately $(top_srcdir) has no meaning in configure.
839# However there are other variables, like CC, which are often used in
840# configure, and could therefore not use this "fixed" $ac_aux_dir.
841#
842# Another solution, used here, is to always expand $ac_aux_dir to an
843# absolute PATH.  The drawback is that using absolute paths prevent a
844# configured tree to be moved without reconfiguration.
