[omniORB] precompiled omnithread.so causes problem with IRIX6.5

[Bruce Visscher]

Vijay,

I remember one of the problems I encountered in early attempts to port
omniORB to OpenVMS was that the pthread_setprio returns the old priority
value on success, rather than 0 for some versions of OpenVMS.

So you will find:

#ifdef __VMS
// pthread_setprio returns old priority on success (draft version 4:
// OpenVms version < 7)
#define THROW_ERRORS(x) { if ((x) == -1) throw omni_thread_fatal(errno);
}
#else
#define THROW_ERRORS(x) { if ((x) != 0) throw omni_thread_fatal(errno);
}
#endif

in src/lib/omnithread/posix.cc

You might want to check if this logic helps your platform as well.  I
don't know of a case where a posix thread function will return anything
other than -1 as the result of an error so I think this is safe in any
case.

HTH,

Bruce Visscher
