Re: CC Mode, labels not fontified

Hi, Simon, Chong!

I've got this problem nailed, I think.

I'm not sure I believe this.  I can't reproduce it.

I'm coding up a fix at the moment.  The idea is to get `c-forward-label'
to indicate in its return code what sort of "label" it's moved over.
"label" here means just about anything with a colon in it apart from a
bitfield specifier in a struct (something like int foo : 2, meaning foo
is -2 .. 1).  It can also be things like "@private" in Objective-C.

`c-font-lock-declarations' will then only fontify a goto-label or a
case-label.

Give me a day or two!
