Perl - Dual-life Socket

I've been working on how to dual-life the Socket module, so it can go on CPAN and give older Perl versions the benefits of recent additions; namely getaddrinfo(3)/getnameinfo(3) wrappings and other IPv6 support.

I have what's currently marked as an unauthorized release now on CPAN, though I'm hoping to get co-maint on it to release officially. In the meantime, it'd be useful to get some smoketest reports on what works and what doesn't. I've tested on Linux at perl 5.10.1, 5.12.4 and 5.14.1. Other OSes, especially MSWin32, would be most appreciated.
