That's purely evil. So have to put your non standard builtin all over
standards compliant code just to shut off a warning that is likely
common. And you're not even supporting the classic lint style comment either.
I think it's ok to make this a separate option, but even putting it in
-Wall would annoy far too many people (including me) for good reasons.
Making it default is just totally wrong.
