This turns out not to be so easy. That patch is intertwined with a lot=20 of changes to the build system that were made only in the trunk, so=20 there's no way to quickly test whether that patch is relevant to the=20 present bug. Since the bug is gone in the trunk, I don't think it's=20 worth putting a lot of effort into fixing it in the emacs-23 branch. Ken
