663 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
665 # Of course, Automake must honor this variable whenever it calls a
666 # tool from the auxiliary directory. The problem is that $srcdir (and
667 # therefore $ac_aux_dir as well) can be either absolute or relative,
668 # depending on how configure is run. This is pretty annoying, since
669 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
670 # source directory, any form will work fine, but in subdirectories a
671 # relative path needs to be adjusted first.
673 # $ac_aux_dir/missing
674 # fails when called from a subdirectory if $ac_aux_dir is relative
675 # $top_srcdir/$ac_aux_dir/missing
676 # fails if $ac_aux_dir is absolute,
677 # fails when called from a subdirectory in a VPATH build with
678 # a relative $ac_aux_dir
680 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
681 # are both prefixed by $srcdir. In an in-source build this is usually
682 # harmless because $srcdir is `.', but things will broke when you
683 # start a VPATH build or use an absolute $srcdir.
685 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
686 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
687 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
688 # and then we would define $MISSING as
689 # MISSING="\${SHELL} $am_aux_dir/missing"
690 # This will work as long as MISSING is not called from configure, because
691 # unfortunately $(top_srcdir) has no meaning in configure.
692 # However there are other variables, like CC, which are often used in
693 # configure, and could therefore not use this "fixed" $ac_aux_dir.
