Hmm, isn't _Bool in the implemenation keyword space anyways? Subject: Re: -ansi -pedantic accepts _Bool without diagnostic

It is, so is _Complex, and that is diagnosed. I'm not saying it's
a conformance problem, just that it's probably a bug.
So? Is this a bug or not? I'd say it's a quality-of-implementation issue, but it probably would be best to diagnose this. I've added such diagnostics for C11 keywords such as _Noreturn and _Static_assert outside C11 mode when adding support for those keywords, for example. So confirmed.
