I would have appreciated a heads-up here, since libc++ no longer builds
with warnings-as-errors.

include/memory:

namespace __has_pointer_type_imp
{
    template <class _Up> static __two __test(...);
    template <class _Up> static char __test(typename _Up::pointer* = 0);
}

template <class _Tp>
struct __has_pointer_type
    : public integral_constant<bool,
sizeof(__has_pointer_type_imp::__test<_Tp>(0)) == 1>
{
};

That first function is not really "unused" (though clang now claims that it
is)
