Oh, I see now --- sorry.

Wow, I looked in hpux.h and saw:#if defined(__hppa)#define HAS_TEST_AND_SETtypedef struct{    int         sema[4];}
slock_t;#ifndef        BYTE_ORDER#define         BYTE_ORDER      BIG_ENDIAN#endif
 

and I see in s_lock.h:#if defined(__hppa)/* * HP's PA-RISC * * Note that slock_t on PA-RISC is a structure instead of
char* (see include/port/hpux.h). * * a "set" slock_t has a single word cleared.  a "clear" slock_t has * all words set
tonon-zero. tas() is in tas.s */#define S_UNLOCK(lock) \    do { \        volatile slock_t *lock_ = (volatile slock_t
*)(lock); \        lock_->sema[0] = -1; \        lock_->sema[1] = -1; \        lock_->sema[2] = -1; \
lock_->sema[3]= -1; \    } while (0)#define S_LOCK_FREE(lock)   ( *(int *) (((long) (lock) + 15) & ~15) != 0)#endif
/*__hppa */
 

Can Linux handle this?  Can you copy the stuff from hpux.h and see if
that works for Linux?

We can't mark this port as working unless we have spinlocks.
