代码_便于移植的数据类型定义

typedef char INT8;  
typedef short INT16;    
typedef int INT32;    
typedef unsigned char UCHAR;    
typedef signed char CHAR;    
typedef unsigned short UINT16;  
typedef unsigned int UINT32;
typedef signed long long INT64;
typedef unsigned long long UINT64;
typedef int BOOL;

规范相应数据类型长度，便于移植。
