Before you actually commit that, once the CVS repository works, this:

 > +(defmacro ad-xemacs-p ()
 > +  ;;Expands into Non-nil constant if we run XEmacs.
 > +  ;;Unselected conditional code will be optimized away during compilation.
 > +  (or (featurep 'xemacs) (string-match "XEmacs" emacs-version)))

isn’t necessary, I had previously removed it intentionally.
