Here is a patch that fixes the below problem for cvs emacs.
The patch prevents the re-fontification of the "case" keyword as a constant.
I also toyed with some code that fontifies the case constants as constants,
as Emacs 19-21 tries to do, but it doesn't (can't) work in all cases. Also,
I think that's probably over the top, so I have left the additional code in
but commented it out.

* progmodes/cc-fonts.el (c-font-lock-declarations): Don't overwrite
fontification for "case" and "default" keywords.
