All you are using very new Emacsen, but Emacs 20 users always
need to employ cl for it.

  remove is a compiled Lisp function in `cl-seq'.
  (remove X Y)
  not documented

I think we should put the compiler macro as follows in
dgnushack.el, or we should use the expanded version of the
macro.

(unless (featurep 'xemacs)
  (define-compiler-macro remove (&whole form item seq)
    (if (>= emacs-major-version 21)
	form
      `(delete ,item (copy-sequence ,seq)))))

(compiler-macroexpand '(remove ITEM SEQ))
 => (delete ITEM (copy-sequence SEQ))

By the way, in this particular case, we have no need to use
`delete' but `delq'. :-)
