8658 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
8659 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
8660 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
8661 #
8662 # Of course, Automake must honor this variable whenever it calls a
8663 # tool from the auxiliary directory.  The problem is that $srcdir (and
8664 # therefore $ac_aux_dir as well) can be either absolute or relative,
8665 # depending on how configure is run.  This is pretty annoying, since
8666 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
8667 # source directory, any form will work fine, but in subdirectories a
8668 # relative path needs to be adjusted first.
8669 #
8670 # $ac_aux_dir/missing
8671 #    fails when called from a subdirectory if $ac_aux_dir is relative
8672 # $top_srcdir/$ac_aux_dir/missing
8673 #    fails if $ac_aux_dir is absolute,
8674 #    fails when called from a subdirectory in a VPATH build with
8675 #          a relative $ac_aux_dir
8676 #
8677 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
8678 # are both prefixed by $srcdir.  In an in-source build this is usually
8679 # harmless because $srcdir is '.', but things will broke when you
8680 # start a VPATH build or use an absolute $srcdir.
8681 #
8682 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
8683 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
8684 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
8685 # and then we would define $MISSING as
8686 #   MISSING="\${SHELL} $am_aux_dir/missing"
8687 # This will work as long as MISSING is not called from configure, because
8688 # unfortunately $(top_srcdir) has no meaning in configure.
8689 # However there are other variables, like CC, which are often used in
8690 # configure, and could therefore not use this "fixed" $ac_aux_dir.
8691 #
8692 # Another solution, used here, is to always expand $ac_aux_dir to an
8693 # absolute PATH.  The drawback is that using absolute paths prevent a
8694 # configured tree to be moved without reconfiguration.
