As SXEmacs also has these macros and uses them extensively throughout
its core lisp, how about adding a form like...

(when (and (fboundp #'with-fboundp)
	   (equal (file-name-nondirectory
		   (describe-symbol-find-file 'with-fboundp))
		  "bytecomp-runtime.elc"))
  (error "bytedecl not loaded: already implemented in your emacs"))

...to the top of bytedecl.el.  That way if any SXEmacs or XEmacs 21.5
user tries to load bytedecl they'll quickly see the error of their
ways.:-)

It might pay to encourage package authors (via bytedecl's commentary)
to use...

(unless (fboundp #'with-fboundp)
  (require 'bytedecl))

...as a further safeguard for 21.5 and SXEmacs users.

They work fine in SXEmacs, so I doubt there'll be any problems for
XEmacs 21.4.
