If anyone knows where F_OK and R_OK (manifest constants needed when calling
"access") can be found when using the above compiler, I'd appreciate hearing
from you by electronic mail.  Note that it isn't any of...

		#include "sys/types.h"  /* for time_t */
		#include "stdio.h"
		#include "ctype.h"
		#include "errno.h"
		#include "string.h"
		#include "limits.h"     /* for CHAR_BIT */
		#include "time.h"
		#include "stdlib.h"
		#include "unistd.h"     /* for F_OK and R_OK */
