2109 * for types < int: (unsigned TYPE)~(unsigned)0
2110 * The argument to ~ must be unsigned so that later signed->unsigned
2111 * conversion can't modify the value's bit pattern (e.g. -0 -> +0),
2112 * and it must not be smaller than int because ~ does integral promotion.
2113 * <type>_MAX: (<type>) (U<type>_MAX >> 1)
2114 * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.
2115 * The latter is a hack which happens to work on some machines but
2116 * does *not* catch any random system, or things like integer types
2117 * with NaN if that is possible.
2118 *
2119 * All of the types are explicitly cast to prevent accidental loss of
2120 * numeric range, and in the hope that they will be less likely to confuse
2121 * over-eager optimizers.
