The following patch allows me to build the 8.3 and 8.4 branches using
Visual Studio 2008, once the build system is patched. But I don't really
know why. HEAD and 9.0 build fine without it. But those branches
branches fail with a complaint about IPPROTO_IPV6 being undefined.
The patch seems harmless enough. But I'd like to know why it's
happening. Does anyone have a clue?
cheers
