I marked this patch as ready for committer.  I confirmed:

* The patch content is correct.

* The patch applies cleanly.  Running "grep -lir wsock32 ." after applying 
the patch shows that wsock32.lib is no longer used.

* The binaries can be built with MSVC 2008 Express.  I didn't try to build 
on MinGW.

* The regression tests pass ("vcregress check").

However, I wonder if some DLL entries in dlls[] in 
src/interfaces/libpq/win32.c should be removed.  winsock.dll should 
definitely be removed, because it is for 16-bit applications.  I don't know 
about the rest.  Especially,  wsock32n.dll and mswsock.dll may also be 
obsolete libraries from their names.  Could you look into this and revise 
the patch if possible?  But I don't mind if you do so.
