For example, `uint8' should 36be the most convenient type that can hold unsigned integers of as many as 378 bits. The `flag' type must be able to hold either a 0 or 1. For most 38implementations of C, `flag', `uint8', and `int8' should all be `typedef'ed 39to the same as `int'. 40------------------------------------------------------------------------------- 41*/ 42typedef int flag; 43typedef int uint8; 44typedef int int8; 45typedef int uint16; 46typedef int int16; 47typedef unsigned int uint32; 48typedef signed int int32; 49#ifdef BITS64 50typedef unsigned long long int uint64; 51typedef signed long long int int64; 52#endif 53 54/* 55------------------------------------------------------------------------------- 56Each of the following `typedef's defines a type that holds integers 57of _exactly_ the number of bits specified.
