On Windows, this code did not handle error conditions correctly at all, since it looked at "errno" which is not used for socket-related errors on that platform. This resulted, for example, in failure to connect to a PostgreSQL server with GSSAPI enabled. We have a convention for dealing with this within libpq, which is to use SOCK_ERRNO and SOCK_ERRNO_SET rather than touching errno directly; but the GSSAPI code is a relative latecomer and did not get that memo. (The equivalent backend code continues to use errno, because the backend does this differently. Maybe libpq's approach should be rethought someday.) Apparently nobody tries to build libpq with GSSAPI support on Windows, or we'd have heard about this before, because it's been broken all along. Back-patch to all supported branches.
