C++11 compatibility.
* Fix string literal concatenation to not be interpreted as UD
literals.
* Add constexpr compatibility for non-integral static members.
* Use __typeof__ instead of typeof (should become decltype once this
actually becomes C++11).
* Add an appropriate cast for atomic_uintptr_t, since moving to C++11
means moving from <stdatomic.h> to <atomic>, which has better
typechecking (hooray for not macros!).
