You may well be right, but looking at the code, I don't really see why.
There's one single consumer of
`c-standard-font-lock-fontify-region-function'?  There's one single
place it's set?  If it isn't set, the function breaks unconditionally?

Or is it set to something else under XEmacs (in code that's not in the
Emacs 24 tree)?
