--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think at least in the past glibc used to add attributes to builtins through
typeof (__builtin_whatever) __builtin_whatever __attribute__((...));
so not sure if we can completely forbid it, but we certainly should forbid when
it has incompatible type or what one defines the body for it.
