1413 * U<TYPE>_MAX: for types >= int: ~(unsigned TYPE)0

1415 * The argument to ~ must be unsigned so that later signed->unsigned

1417 * and it must not be smaller than int because ~ does integral promotion.

1419 * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.

1421 * does *not* catch any random system, or things like integer types
1422 * with NaN if that is possible.
