- * Try to figure out max and min values for the integral types. THE CORRECT
- * SOLUTION TO THIS MESS: ADAPT enquire.c FROM GCC INTO CONFIGURE. The
- * following hacks are used if neither limits.h or values.h provide them:
- * U<TYPE>_MAX: for types >= int: ~(unsigned TYPE)0
- * for types < int: (unsigned TYPE)~(unsigned)0
- * The argument to ~ must be unsigned so that later signed->unsigned
- * conversion can't modify the value's bit pattern (e.g. -0 -> +0),
- * and it must not be smaller than int because ~ does integral promotion.
- * <type>_MAX: (<type>) (U<type>_MAX >> 1)
- * <type>_MIN: -<type>_MAX - <is_twos_complement_architecture: (3 & -1) == 3>.
- * The latter is a hack which happens to work on some machines but
- * does *not* catch any random system, or things like integer types
- * with NaN if that is possible.
- *
- * All of the types are explicitly cast to prevent accidental loss of
- * numeric range, and in the hope that they will be less likely to confuse
- * over-eager optimizers.
