If __int128 were a typedef, then no diagnostic would be required for
code that uses it. But in fact it's a gcc implementation-defined
keyword. I *think* a diagnostic is required for any use of it.
(Of course that requirement doesn't apply to non-conforming
compilers, such as gcc in its default mode.)

Yes.
