Win32: MSVC 2015 compatibility. Resolved warnings about declarations that hide previous local declarations. Warnings about WSASocketA() being deprecated resolved by explicit use of WSASocketW() instead of WSASocket(). When compiling without IPv6 support, WinSock deprecated warnings are disabled to allow use of gethostbyname().
