building postgresql 7.4.2 on 5.0.7: setsockopt(TCP_NODELAY) failed

Has anyone successfully built postgresql 7.4.2 on 5.0.7?

Was using postgresql 7.3.4 that came with Update Pack 2 for 5.0.7, but
wanted to sync versions with a 7.4.x Cygwin build being used for
development.

It wouldn't configure and compile until a gcc option (-b elf) was removed,
but unix socket connections fail with the following logged error:

setsockopt(TCP_NODELAY) failed: Protocol not available

Connection to the server therefore only works with a local tcp connection,
i.e.
    psql -h localhost template1.

One post in the postgresql archives mentions the problem, with a different
syntactical approach to removing the -b elf compiler option, but doesn't
provide details of a fix for the rest.

Anyone from SCO with a fix? I didn't try and compile 7.3.4 from source, but
the same problem may have occurred with the earlier version.

Thanks,

David P. Lurie
