有哪位老兄认识CY啊？？？？？？？？？？

上面弄错了，是这样的：
typedef struct  tagCY
    {
    LONGLONG int64;
    } CY;#else /* 0 */
/* real definition that makes the C++ compiler happy */
typedef union tagCY {
    struct {
#ifdef _MAC
        long      Hi;
        long Lo;
#else
        unsigned long Lo;
        long      Hi;
#endif
    };
    LONGLONG int64;
} CY;
