More problems compiling PostgreSQL 6.4 on Digital Unix 4.0d - Mailing list pgsql-admin

I am still having problems compiling PostgreSQL 6.4 on Digital Unix 4.0d
(DEC Alpha platform).  The problems now are with the macro:

  S_INIT_LOCK( )

I can't figure out how this macro is supposed to work and what data type
it is asking for.  Here are the error messages and code snippets of
interest.  Can someone help me out?

Thanks,
Carl


From:

  src/include/storage/s_lock.h:

#if defined(__alpha)

 * OSF/1 (Alpha AXP)

 * (see storage/ipc.h).

#define TAS(lock)    (msem_lock((lock), MSEM_IF_NOWAIT) < 0)
#define S_UNLOCK(lock)    msem_unlock((lock), 0)
