Windows sockets take a SOCKET HANDLE object instead of a file descriptor. Wrap them in the same way that gnulib does so that they use C runtime file descriptors. While we could in theory use GSocket, it is hard to get the exact same semantics libvirt has for its current socket usage. Wrapping the Winsock2 APIs is thus the easiest approach in the short term. In changing the socke wrappers we need to re-implement the nonblocking function too, since the GNULIB impl expects to be used with the GNULIB sockets wrappers.
