It's not targeted for the unix platform, all of these function calls are
Winsock.dll calls (Microsoft's BSD-ish sockets implementation). I would
imagine the ODBC driver links to the dll at runtime (I seem to remember
that you need a definitions?? file to pull in Winsock calls at runtime).
If not you can link against the static library Wsock32.lib.
The ODBC driver uses TCP/IP socket calls to talk between your client and
the Postgres backend, thats why these calls are needed.
Hope this helps...
