Bug #1834: 1.9.2-dev fails to compile socket with IPv6 and MinGW 3.4.5

Hello,

Sorry, I don't have much time now to resolve this problem.

Roughly summarize of my understanding.

(1) MinGW's IPv6 support seems to be broken.
    VC++6 has same problem, I know.
    So, mswin's ipv6 support is now disabled by default.

(2) --disable-ipv6 option of configure is your workaround.

(3) link errors with --enable-wide-getaddrinfo is ruby's bug.

I'm going to look into MinGW headers then.

Wasn't aware of that, will try it, but first try to get IPv6 with MinGW to work.

Good to know.
