GNU Emacs 19 certainly had X support, and there was a Win port of it
as well.  XEmacs works well in both of those environments, too.
(Unfortunately, it doesn't in Max OS X, yet.)

There don't seem to be all that many differences unless you're doing
hairy UI stuff, where things become utterly different.  I have a major
mode (for APL) that is absolutely XEmacs-only; I don't think it's even
possible to do what it does in GNU Emacs, and certainly it if's
possible it would be very different.
