   # 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.
