OK. Then I didn't understand you right. Sorry.

That's actually what I have at the moment.

(if (fboundp 'completing-read-multiple)
    (defalias 'TeX-completing-read-multiple 'completing-read-multiple)
  (defun TeX-completing-read-multiple
    (prompt table &optional predicate require-match initial-input
           hist def inherit-input-method)
    "Poor mans implementation of Emacs' `completing-read-multiple' for XEmacs."
    (require 'multi-prompt)
    (multi-prompt "," nil prompt table predicate require-match initial-input 
hist)))


I just dicovered a difference in `multi-prompt' and `crm'.  If the
second argument of `multi-prompt' is non-nil the values you are
completing on are supposed to be unique and there is no way to specify
that in `completing-read-multiple' so we cannot replace the two
occurences of `multi-prompt' in latex.el with
`completing-read-multiple' without loosing that.

Indeed.

Agreed.
