--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think even with _BitInt support they won't be useful for C++.
The reason they exist is that in C just using __builtin_{clz,ctz,popcount,...}g
would result in macro arguments of type generic macros being used multiple
times, which is a bad idea when one deeply nests these macros.
In C++, <stdbit.h> doesn't provide macros, but function templates.
And function templates don't suffer from the same problem, they name the
function arguments and can use them as many times as they want.
