+       * org-compat.el (org-get-x-clipboard-compat): Add a compat
+       function for fetching the X clipboard on XEmacs and GNU Emacs 21.

+       * org-remember.el (org-get-x-clipboard): Use the compat
+       function to get clipboard values when x-selection-value is

+       value.

        * lisp/org-clock.el (org-update-mode-line): Support limiting the
        modeline clock string, and display the full todo value in the
        tooltip. Set a local keymap so mouse-3 on the clock string goes to
