GNU Emacs users should not share .emacs between XEmacs and GNU Emacs unless they really know what they're doing. I recommend moving to the .xemacs/init.el model because it separates init.el from custom.el. The best way to do this is to just cp .emacs .xemacs/init.el, then copy the custom-set-* forms to .xemacs/custom.el and remove them from init.el. After that XEmacs should ignore .emacs (but it's there as a backup, or for GNU Emacs!) If you have significant custom-izations migration can be dangerous (I think Mike has fixed the most recent problem, and most problems I can imagine, but I'm not sure the risk of losing custom-izations is zero yet). .xemacs is a reasonable place to keep shared init code, eg in shared-init.el. Then put (load-library "shared-init") in your .emacs and init.el. custom.el may be sharable, but there are a number of tricks you can do with faces in GNU Emacs that don't work in XEmacs yet. It's probably preferable to keep those separate, too. (And I don't know if GNU Emacs will write customizations to a file other than .emacs.) Sorry.
