Using Microsoft Visual Studio Express 2013 for Windows Desktop.

Adding 'socket' nosy list, as Antoine may have a stronger opinion about changing _socket to avoid these warnings - they aren't all in Windows-exclusive code. Or I'm happy to add the suppression to the build if that's the better option.

I'll work up a patch for the GetVersion deprecations. I believe they're mostly checking for Vista, which we can assume now, so they aren't necessary.

Patch attached.

Interesting, once you declare Vista as the minimum API set, WinSock claims to support CMSG_LEN which enables sendmsg() et al support in _socket. Since the WinSock API bears little relation to the POSIX(?) API, it doesn't build, so I've just undef'd CMSG_LEN when building socket.

Anyone got a chance to double-check my patch for me? I think it's fine, unless someone really wants me to turn all the "#ifdef CMSG_LEN" checks into "#ifdef HAVE_CMSG" (which I *think* would require autoconf updates, which I am totally unqualified to do...)

The _WINSOCK_DEPRECATED_NO_WARNINGS question is still open, but the rest of the deprecations should be clear now.

There is only one deprecation warning left in current builds:

..\Modules\expat\xmlparse.c(796): warning C4996: 'getenv': This function or variable may be unsafe. Consider using _dupenv_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
