Real-Time signals & GDB

I downloaded gdb 5.0, and successfully compiled it for Solaris 7/SPARC.
However, the same problem persists as was present under 4.18.

When I send a real-time signal from one thread to another thread, gdb halts
with the following message:

"Program received signal ?, Unknown signal.
[Switching to LWP 7]
0xfef93224 in _libc_sigtimedwait () from /usr/lib/"

I had initally issued a "handle all", so when I continue, I expect the
signal to get passed on to my process.  I do have a thread in a
sigwaitinfo() for the RT signal I just sent.  Why won't gdb pass this signal
to my process?

   I am using gdb 4.18 on Solaris 7/SPARC UltraIII.

Try 5.0 (if you can get it to compile).
