For example, `uint8' should 28be the most convenient type that can hold unsigned integers of as many as 298 bits. The `flag' type must be able to hold either a 0 or 1. For most 30implementations of C, `flag', `uint8', and `int8' should all be `typedef'ed 31to the same as `int'. 32------------------------------------------------------------------------------- 33*/ 34typedef int flag; 35typedef int uint8; 36typedef int int8; 37typedef int uint16; 38typedef int int16; 39typedef unsigned int uint32; 40typedef signed int int32; 41#ifdef BITS64 42typedef unsigned long long int uint64; 43typedef signed long long int int64; 44#endif 45 46/* 47------------------------------------------------------------------------------- 48Each of the following `typedef's defines a type that holds integers 49of _exactly_ the number of bits specified.
