XP Home or Pro? What version of Cygwin?

FWIW, I saw warnings I never saw before when compiling Python under
Cygwin gcc 3.3.1 yesterday. I presume gcc 3.3.1 is pickier or more
"chatty" than it was before. Anyway, Python still passed its full
regression test.

Are you getting hangs or connection refused errors. The Cygwin
PostgreSQL README documents the following issue:

1. make check can generate spurious regression test failures due to
overflowing the the listen() backlog queue which generates
connection refused errors. Note that make installcheck does not
have this problem since it runs all tests sequentially instead of in
large concurrent groups.

The above will not have any affects under Cygwin. IIRC, the listen()
backlog is 200 under server versions of Windows (e.g., 2000 Advanced
Server) and 5 on all other versions (e.g., XP Pro).

Can you try make installcheck instead?

Thanks,
Jason
