What we have for IRIX is

#if defined(__sgi)
/*
* SGI IRIX 5
* slock_t is defined as a unsigned long. We use the standard SGI
* mutex API.
*
* The following comment is left for historical reasons, but is probably
* not a good idea since the mutex ABI is supported.
*
* This stuff may be supplemented in the future with Masato Kataoka's MIPS-II
* assembly from his NECEWS SVR4 port, but we probably ought to retain this
* for the R3000 chips out there.
*/
#include "mutex.h"
#define TAS(lock) (test_and_set(lock,1))
#define S_UNLOCK(lock) (test_then_and(lock,0))
#define S_INIT_LOCK(lock) (test_then_and(lock,0))
#define S_LOCK_FREE(lock) (test_then_add(lock,0) == 0)
#endif /* __sgi */

Doesn't look to me like it's likely to work on anything but IRIX ...
