--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. This is a minor documentation but it would be nice to have this
documented.

Also related it would be nice to have _Bool as an extension for C++ so it might
be easier to compile some C99/C17 code with the C++ front-end too.
