I don't see that the branch updated nt/epaths.nt (and in top-level
Makefile.in), without which nothing useful can happen with
PATH_REL_LOADSEARCH.

And if PATH_REL_LOADSEARCH is defined on MS-Windows like I think it
should, you will probably have problems using it in a regex, because
it will include the unexpanded %emacs_dir% part?
