kenjiArai 1:9db0e321a9f4 25 * - - adds missing std::nullptr_t
kenjiArai 1:9db0e321a9f4 26 * - For all toolchains:
kenjiArai 1:9db0e321a9f4 27 * - - MSTD_CONSTEXPR_XX_14 macros that can be used to mark
kenjiArai 1:9db0e321a9f4 28 * things that are valid as constexpr only for C++14 or later,
kenjiArai 1:9db0e321a9f4 29 * permitting constexpr use where ARM C 5 would reject it.
