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.
