    37  * According to ANSI (section 2.2.4.2), the values below must be usable by
    38  * #if preprocessing directives.  Additionally, the expression must have the
    39  * same type as would an expression that is an object of the corresponding
    40  * type converted according to the integral promotions.  The subtraction for
    41  * INT_MIN, etc., is so the value is not unsigned; e.g., 0x80000000 is an
    42  * unsigned int for 32-bit two's complement ANSI compilers (section 3.1.3.2).
    43  * These numbers are for the default configuration of gcc.  They work for
    44  * some other compilers as well, but this should not be depended on.
