--- Comment #11 from Peter Bergner <bergner at gcc dot gnu.org> --- I have a patch I'm testing for the second problem. Basically, it verifies that the builtin we are overloading has already been defined or not. If it hasn't (ie, it wasn't supported for some reason, like dfp being disabled), then we skip defining this builtin too.
