The documentation is misleading, as using the new API actually
causes WSASocket to fail.
New behaviour:
On windows vista or earlier: skip the new API, use old one
On windows 7: try the new API first, if it fails try the old one
On windows 8: try the new API only
The windows 7 behaviour is because we don't know if the service
pack has been installed or not. (And IT departments may have
specifically installed/blocked the hotfix)
