   678 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
   679 #
   680 # Of course, Automake must honor this variable whenever it calls a
   681 # tool from the auxiliary directory.  The problem is that $srcdir (and
   682 # therefore $ac_aux_dir as well) can be either absolute or relative,
   683 # depending on how configure is run.  This is pretty annoying, since
   684 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
   685 # source directory, any form will work fine, but in subdirectories a
   686 # relative path needs to be adjusted first.
   687 #
   688 # $ac_aux_dir/missing

   690 # $top_srcdir/$ac_aux_dir/missing
   691 #    fails if $ac_aux_dir is absolute,
   692 #    fails when called from a subdirectory in a VPATH build with
   693 #          a relative $ac_aux_dir
   694 #
   695 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
   696 # are both prefixed by $srcdir.  In an in-source build this is usually
   697 # harmless because $srcdir is `.', but things will broke when you
   698 # start a VPATH build or use an absolute $srcdir.
   699 #
   700 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
   701 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
   702 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
   703 # and then we would define $MISSING as
   704 #   MISSING="\${SHELL} $am_aux_dir/missing"
   705 # This will work as long as MISSING is not called from configure, because
   706 # unfortunately $(top_srcdir) has no meaning in configure.
   707 # However there are other variables, like CC, which are often used in
   708 # configure, and could therefore not use this "fixed" $ac_aux_dir.
   709 #
   710 # Another solution, used here, is to always expand $ac_aux_dir to an
