+/*
+ * 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.
