Re: [PATCH v3 01/14] mingw: add network-wrappers for daemon

From: Mike Pape<redacted>

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().
