* #if preprocessing directives. Additionally, the expression must have the

* same type as would an expression that is an object of the corresponding
|
|
* type converted according to the integral promotions. The subtraction for
|
|
* INT_MIN and LONG_MIN is so the value is not unsigned; 2147483648 is an
|

* unsigned int for 32-bit two's complement ANSI compilers (section 3.1.3.2).
|
|
* These numbers work for pcc as well. The UINT_MAX and ULONG_MAX values
