(defmacro dh-when-xemacs (&rest forms) ;; (declare (indent 0))
  (when (featurep 'xemacs) (cons 'progn forms)))

(defmacro dh-when-gnu-emacs (&rest forms) ;; (declare (indent 0))
  (unless (featurep 'xemacs) (cons 'progn forms)))

(defvar dh-elisp-dir
  (concat "~/.elisp/"
          (dh-when-xemacs "xemacs/")
          (dh-when-gnu-emacs "emacs/")
          "/"))

(dolist (path (list dh-elisp-dir
                    (concat dh-elisp-dir "maxima/")
