I've been mucking about in top-of-trunk but not compiling under Windows 
so would like to see the errors so I might fix things up.

More generally, that email talks about the netserver side being asked to 
run a test it does not know about.  Changing versions is how one got 
netserver to know about the test.

Unless you (know to) disable the WANT_MIGRATION from config.h, the Linux 
version will compile things to "migrate" several of the classic tests to 
the "omni" code and so will have asked the Windows side to run an omni 
test.  Since the Windows side was compiled without omni support, it did 
not know about the test, and so returned the 998. I suspect if you tried 
from Windows to Linux it would be OK at least as far as running goes.

happy benchmarking,
