Yeah, the problem is that the msvc build has no intelligence to detect the IPv6 APIs to define HAVE_IPV6. So that needs to be developed.

The configure test just looks for a definition of struct sockaddr_in6. Taking a quick look It seems to me like this is unconditionally there in the MSVC WS2tcpip.h , so maybe we should just force it for MSVC.

That was my question. I just built with ipv6 enabled using my msvc build on
my primary machine which does *not* have ipv6, and it still passes
regression tests fine.

Given that we have a runtime check, is there any reason at all not to
enable ipv6 on all builds on msvc?

(FWIW, it's been in the platform SDK at least since Windows 2000)

If we could use configure for MSVC this would have Just Happened (tm). I wonder how many other little bits we miss out on?

Anyway, the obvious fix seems to be to add a line to src/tools/msvc/ to #define HAVE_IPV6 1 in pg_config.h
