Mmm... that doesn't look good. ;-)

Well, it seems that a fear I had is now becoming reality... I suspect the
problem is with the macro add-to-listq. In Emacs 22, add-to-list allows an
optional argument that XEmacs doesn't allow. I defined add-to-listq to work
around this. Now it seems that Emacs 21 also doesn't know about this
argument...

A quick fix would be to replace the definition of add-to-listq in the
source file with the following (it appears at the top of the file, directly
after the license and copyright notice):

(defmacro add-to-listq (listvar element &optional append fn)
  (if (or (featurep 'xemacs)
	  (string< emacs-version "22"))
      `(add-to-list (quote ,listvar) ,element ,append)
    `(add-to-list (quote ,listvar) ,element ,append ,fn)))

Not sure if this is the best way to test for the version of Emacs, but it
should work for you.
