This turns out not to be so easy. That patch is intertwined with a lot
of changes to the build system that were made only in the trunk, so
there's no way to quickly test whether that patch is relevant to the
present bug. Since the bug is gone in the trunk, I don't think it's
worth putting a lot of effort into fixing it in the emacs-23 branch.
