That should work.

I described this a few days ago. It's because include both <winsock.h>
and <winsock2.h> are included. We should only use <winsock2.h> IMHO.
That doesn't mean libcurl programs must have Winsock 2 at runtime (that
is determined by the value in WSAStartup().

So OTOH src/main.c and include/curl/multi.h needs to be patched.
