* libc/include/stdint.h (INT32_MIN, INT32_MAX, UINT32_MAX,
        INT_LEAST32_MIN, INT_LEAST32_MAX, UINT_LEAST32_MAX): Define to
        constants with "long" types where appropriate.
        (INT_FAST8_MIN, INT_FAST8_MAX, UINT_FAST8_MAX, INT_FAST16_MIN,
        INT_FAST16_MAX, UINT_FAST16_MAX, INT_FAST32_MIN, INT_FAST32_MAX,
        UINT_FAST32_MAX, INT_FAST64_MIN, INT_FAST64_MAX, UINT_FAST64_MAX):
        Correct to match logic for defining corresponding types.
        (INTMAX_MAX, INTMAX_MIN, UINTMAX_MAX): Define.
        (SIZE_MAX): Define using __SIZE_MAX__ if available.
        (PTRDIFF_MAX): Define using __PTRDIFF_MAX__ if available.
        (PTRDIFF_MIN): Define in terms of PTRDIFF_MAX.
        (WCHAR_MAX, WCHAR_MIN, WINT_MAX, WINT_MIN): Define.
        (UINT8_C, UINT16_C): Define to give signed values if corresponding
        types would promote to int.
