I agree that it doesn't make a ton of sense to guard this on the version, since the GCC folks make it very clear that they don't intend to support the use of the builtin directly. But I also don't think that we should pessimize the Clang version here. We should simply resolve the `__remove_pointer_t` alias to either `remove_pointer<>::type` for GCC or `__remove_pointer()` for Clang.
