  Log:
    socket: system getaddrinfo on Windows
    
    * ext/socket/extconf.rb: use system getaddrinfo, getnameinfo, and
      freeaddrinfo on Windows if they are provided.  they conflict
      with addrinfo.h and cannot compile.  conftest.exe linked against
      msvcr90.dll segfaults when invoked in extconf.rb for unknown
      reason, and failed to check them.
