Problem with font-lock-add-keywords

[remi . ricard]

Hi,

I was using emacs 21.3 and then switched to emacs 22.3 (on Windows)
GNU Emacs 22.3.1
Copyright (C) 2008 Free Software Foundation, Inc.

The following lines were working in 21.3
(font-lock-add-keywords
 'c++-mode
 '(
   ("\\<[0-9]+\\.[0-9f]+\\>" 0 font-lock-floatnumber-face)
   ("[^_]\\<\\([0-9]+\\)\\>" (1 font-lock-number-face))
   ("\\<0x[0-9a-fA-F]+\\>" (0 font-lock-hexnumber-face))
   ("[{}()<>=;:+\\*\\/\\[]\\|\\]\\|\\-" (0 font-lock-keys-face))
   ("\\<TRUE+\\>" (0 font-lock-constant-face))
   ("\\<FALSE+\\>" (0 font-lock-constant-face))
   ))

Now in 22.3 I'm getting the follwing error message
Error during redisplay: (invalid-function (\<[0-9]+\.[0-9f]+\> 0 font-
lock-floatnumber-face)) [3 times]

Since my lisp is not that good. I'm asking for help after searching
the web and finding nothing about this
problem.
