The form `(if (featurep 'xemacs) ...)' is special for Emacs 22
and greater, and XEmacs 21.5.  This makes the byte-compiler
completely ignore XEmacs code when compiling under Emacs (and
Emacs code when compiling under XEmacs).  So do `when', `cond',
etc.   So, I think we can remove those `defalias-maybe's.  I'll
work on this, later.  Thanks.
