Oh, I see now --- sorry.

Wow, I looked in hpux.h and saw:

#if defined(__hppa)

#define HAS_TEST_AND_SET
typedef 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 to non-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.
