It is partly a version problem. With 'GNU Emacs 22.3.1 (i586-suse-
linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2008-12-03 on build19' it works with a few modifications.
With:
    (defun buffer-count-words()
      (interactive)
      (how-many "\\w+" (point-min) (point-max))
      )
and
    (defun buffer-update-word-count()
      (interactive)
      (setq buffer-count-words
            (number-to-string (buffer-count-words))
            )
      (force-mode-line-update)
      )
it works.

The systems I can update, I am going to update. For the system I can
not update I have to copy how-many out of replace.el.
