Additionally, the expression must have the 41249508Sivoras * same type as would an expression that is an object of the corresponding 42249508Sivoras * type converted according to the integral promotions. The subtraction for 43249564Sivoras * INT_MIN, etc., is so the value is not unsigned; e.g., 0x80000000 is an 44249564Sivoras * unsigned int for 32-bit two's complement ANSI compilers (section 3.1.3.2). 45249508Sivoras * These numbers are for the default configuration of gcc. They work for 46249508Sivoras * some other compilers as well, but this should not be depended on. 47249508Sivoras */ 48249508Sivoras 49249508Sivoras#define __CHAR_BIT 8 /* number of bits in a char */ 50249508Sivoras 51249564Sivoras#define __SCHAR_MAX 0x7f /* max value for a signed char */ 52249508Sivoras#define __SCHAR_MIN (-0x7f-1) /* min value for a signed char */ 53249508Sivoras 54249508Sivoras#define __UCHAR_MAX 0xffU /* max value for an unsigned char */ 55249508Sivoras 56249508Sivoras#define __USHRT_MAX 0xffffU /* max value for an unsigned short */ 57249508Sivoras#define __SHRT_MAX 0x7fff /* max value for a short */ 58249564Sivoras#define __SHRT_MIN (-0x7fff-1) /* min value for a short */ 59249564Sivoras 60249564Sivoras#define __UINT_MAX 0xffffffffU /* max value for an unsigned int */ 61249564Sivoras#define __INT_MAX 0x7fffffff /* max value for an int */ 62249564Sivoras#define __INT_MIN (-0x7fffffff-1) /* min value for an int */ 63249508Sivoras 64249508Sivoras#define __ULONG_MAX 0xffffffffffffffffUL /* max for an unsigned long */ 65249508Sivoras#define __LONG_MAX 0x7fffffffffffffffL /* max for a long */ 66249564Sivoras#define __LONG_MIN (-0x7fffffffffffffffL-1) /* min for a long */ 67249564Sivoras 68249508Sivoras/* Long longs and longs are the same size on the IA-64. */ 69249564Sivoras /* max for an unsigned long long */ 70249564Sivoras#define __ULLONG_MAX 0xffffffffffffffffULL 71249508Sivoras#define __LLONG_MAX 0x7fffffffffffffffLL /* max for a long long */ 72249508Sivoras#define __LLONG_MIN (-0x7fffffffffffffffLL-1) /* min for a long long */ 73249564Sivoras 74249564Sivoras#define __SSIZE_MAX __LONG_MAX /* max value for a ssize_t */ 75249564Sivoras 76249564Sivoras#define __SIZE_T_MAX __ULONG_MAX /* max value for a size_t */ 77249564Sivoras 78249508Sivoras#define __OFF_MAX __LONG_MAX /* max value for an off_t */ 79249508Sivoras#define __OFF_MIN __LONG_MIN /* min value for an off_t */ 80249508Sivoras 81249508Sivoras/* Quads and longs are the same.
