00疼啊！windows下的 pthread_t竟然是个结构体，
linux下边，却是 typedef unsigned long int pthread_t;
无聊。。。！！！

/*
 * Generic handle type - intended to extend uniqueness beyond
 * that available with a simple pointer. It should scale for either
 * IA-32 or IA-64.
 */
typedef struct {
    void * p;                   /* Pointer to actual object */
    unsigned int x;             /* Extra information - reuse count etc */
} ptw32_handle_t;
