added ug_gai_strerror Default to gai_strerror, but use WSAGetLastError() in Windows. This solves a problem with localized error messages but with a wrong non-ASCII characters. Instead of gai_strerror, WSAGetLastError is preferred according the Microsoft MSDN docs (thread safety). Also using get_win_error() to ensure non-localized output (preferred).
