  39  * According to ANSI (section 2.2.4.2), the values below must be usable by
  40  * #if preprocessing directives.  Additionally, the expression must have the
  41  * same type as would an expression that is an object of the corresponding
  42  * type converted according to the integral promotions.  The subtraction for
  43  * INT_MIN and LONG_MIN is so the value is not unsigned; 2147483648 is an
  44  * unsigned int for 32-bit two's complement ANSI compilers (section 3.1.3.2).
  45  * These numbers work for pcc as well.  The UINT_MAX and ULONG_MAX values
  46  * are written as hex so that GCC will be quiet about large integer constants.
