Bug #15211 seems to be a duplicate of this bug.  It's amazing how a bug
like this can remain undetected for over a decade, then suddenly two
people report it within a few hours of eachother.

Would you please try out the patch from #15211, and let me know whether
it fixes the bug, doesn't quite fix it, or there are unwanted side
effects.  Here it is again:

          (save-excursion
            (goto-char type-start)


I'll just repeat what I said in #15211: the code in CC Mode took trouble
to _exclude_ "type2" from being fontified, and I don't understand why.
There may be side effects from this patch.

Thanks for reporting this bug, and thanks for making it a high quality
bug report.
