Good job, Changyong.


Regarding R_OK, I 

	#include <sys/unistd.h>.

Here is what has been included in unistd.h:

/* Symbolic constants for the "access" routine: */
#define R_OK    4       /* Test for Read permission */
#define W_OK    2       /* Test for Write permission */
#define X_OK    1       /* Test for eXecute permission */
#define F_OK    0       /* Test for existence of File */


--Xin
