But CC Mode fontification has never been intended to flag invalid
syntax: instead of not being fontified at all, invalid syntax is simply
fontified every which way.  This is not a problem one option can solve;
it will require large scale redesign of CC Mode, and detecting invalid
syntax is more the forte of c-ts-mode anyway.

Thanks.
