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?
