When the first XEmacs 21 is out, the site-lisp directory will be mostly obsolete and people urged to use the package directories instead. This should be enough to distinguish both elcs. IMHO, application maintainers should then consider GNU Emacs and XEmacs as 2 different Emacsen, which means installing elisp files in 2 different places and compiling them differently. Obviously, this doesn't solve the problem of using both Emacsen with an XEmacs prior to 21, but still, the problem is solved (in 21) by using a different directory structure. For the same reason, it don't think changing the extension would be usefull, while I'm not against it. I agree with Kyle that if someone has to change, it's us. -- / / _ _ Didier Verna http://www.inf.enst.fr/~verna/ - / / - / / /_/ / E.N.S.T.
