It's been reported that IPv6 scoped addresses (as defined in RFC 4007), such as fe80::200:e2ff:fe65:9ce%4, don't work correctly on Windows XP Home + XP2. The error is "Network error: No route to host". SecureCRT does work, which suggests that we might just need to invoke getaddrinfo() differently. Scoped addresses work on Unix (NetBSD at least).

SGT, 2006-12-24: Jeroen Massar, the original author of PuTTY's IPv6 code, has supplied a patch which fixes this. Users experiencing this bug might like to download a post-r7007 snapshot and make sure the problem has gone away.
