> Does gcc have any `using_if_exists` attribute?

Nope, it doesn't. The idea is that if folks want to use GCC, they need to provide a compliant C Standard Library, or else we have to jump through a bunch of hoops (basically the world as it were before `using_if_exists`).

So if you update libc++ and Clang in lockstep, I don't think this is going to cause you any trouble.
