[PATCH/RFC 01/11] mingw: add network-wrappers for daemon
From: Mike Pape <dotzenlabs@gmail.com>
git-daemon requires some socket-functionality that is not yet supported in the Windows-port. This patch adds said functionality, and makes sure WSAStartup gets called by socket(), since it is the first network-call in git-daemon. In addition, a check is added to prevent WSAStartup (and WSACleanup, though atexit) from being called more than once, since git-daemon calls both socket() and gethostbyname().
