-Summary: IPv6 not supported on Windows
+Summary: IPv6 not supported on Cygwin
 
 IPv6 does not appear to work on Windows, even though it is enabled (and 
 works fine using MS).
 
 To reproduce, compile and run the following code snippet (taken from bug 
 #81965) on Windows (with Microsoft TCP/IP version 6 installed):

+IPv6 support does not seem to be implemented yet on cygwin.  See
+http://win6.jp/Cygwin/index.html for more info.
+
+We deliberately disable IPv6 for the windows build as the headers
+indicate that the necessary support is present, but the
+implementations of the functions such as inet_ntop() are not in the
+library.
+
+It might be possible to remove this check (see the top of
+metadata/socket-io.c) when building using the VS project, but someone
+with VS will have to test and contribute that.
