That's no problem because first, as mentioned before, we have an
alternative implementation in place and second, a fix in CVS Emacs
won't help us with Emacs 21 in case there are the same problems.

We discussed this quite extensively on the AUCTeX mailing list and
that's my opinion as well.  Besides, the implementation lead to
strange effects on Emacs 21 (Xaw toolkit). I got a "Minibuf" menu with
menu entries from the LaTeX menu because the minibuffer was activated
for the master file question while the LaTeX menu was open.
Alternatively Emacs simply segfaulted.
