It is mingw-w64 (http://mingw-w64.sourceforge.net/) where
the provided ws2tcpip.h header doesn't include winsock2.h.
The mingw32 header does include it, for convenience as it
seems, which is why it works for you. We (mingw-w64) can do
the same for convenience if it is truly necessary, although
the problem is that not every header from every source have
to do it that way.
