;; Compatibility layer betwean XEmacs and GNU Emacs.  However xwem
;; still can't run on GNU Emacs.

;;; Code:

(defvar xwem-gnuemacs-p (string-match "GNU Emacs" emacs-version)
  "Non-nil when running under GNU Emacs.")

(defun xwem-define-prefix-command (name &optional mapvar)
  "Compat version for `define-prefix-command'."
  (if xwem-gnuemacs-p
      (define-prefix-command name)
    (define-prefix-command name t)))

(unless (fboundp 'set-keymap-default-binding)
  (fset 'set-keymap-default-binding
	#'(lambda (keym cmd) (define-key keym [t] cmd))))

(unless (fboundp 'events-to-keys)
  (defalias 'events-to-keys 'identity))
