Hmm...  There's also

#define __IGNORE_alarm
#define __IGNORE_creat
#define __IGNORE_getegid
#define __IGNORE_geteuid
#define __IGNORE_getgid
#define __IGNORE_getpid
#define __IGNORE_getppid
#define __IGNORE_getuid
#define __IGNORE_pause
#define __IGNORE_time
#define __IGNORE_utime
#define __IGNORE_umount2

in there...
