2099 * Try to figure out max and min values for the integral types. THE CORRECT

2101 * following hacks are used if neither limits.h or values.h provide them:
2102 * U<TYPE>_MAX: for types >= int: ~(unsigned TYPE)0
2103 * for types < int: (unsigned TYPE)~(unsigned)0
2104 * The argument to ~ must be unsigned so that later signed->unsigned
2105 * conversion can't modify the value's bit pattern (e.g. -0 -> +0),
2106 * and it must not be smaller than int because ~ does integral promotion.
2107 * <type>_MAX: (<type>) (U<type>_MAX >> 1)
2108 * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.
2109 * The latter is a hack which happens to work on some machines but
2110 * does *not* catch any random system, or things like integer types
2111 * with NaN if that is possible.
2112 *
2113 * All of the types are explicitly cast to prevent accidental loss of
2114 * numeric range, and in the hope that they will be less likely to confuse
2115 * over-eager optimizers.
