+Subject: [PATCH 3/3] only translate winsock errors for old gnutls versions
+
+Bugfix: https handshake fails using gnutls 3 on windows
+http://sourceforge.net/tracker/index.php?func=detail&aid=3441084&group_id=976&atid=100976
+
+New gnutls versions have an error handler that knows about Winsock
+errors, which is why gnutls_transport_set_global_errno()
+was deprecated and then removed.
+
+This is a correction of commit f5bb370 (blame me) which meant
+to reimplement gnutls_transport_set_global_errno(), which is not
+necessary.
