Subject RE: [PATCH] Regarding semun definition in proc_mutex.h

Yep - with HP-UX running on 64-bit Itanium, and using the 64-bit data model.
The side effect of having the "long val" in the union definition is that
it'll have corrupted the mutex/semaphore while creating the proc_mutex
itself (proc_mutex_sysv_create). On HP-UX, the symptom was that the
listener_thread hangs while doing a SAFE_ACCEPT.

Thanks,

So I guess sizeof(long) is 8 bytes on 64-bit HP-UX?  sizeof(long) is
still 4 on 64-bit AIX.
