Mac OS X 10.6 (SnowLeopard)上で trunk(r27662) の make test-all すると test_socket.rb が 1 Error になります。

2. Error:
   test_tcp(TestSocket):
   Errno::EINVAL: Invalid argument - connect(2)
   /Users/nagachika/opt/ruby-trunk/src/ruby-trunk/.ext/common/socket.rb:37:in connect' /Users/nagachika/opt/ruby-trunk/src/ruby-trunk/.ext/common/socket.rb:37:in connect_internal'

ext/socket/lib/socket.rb の AddrInfo#connect_address で MacOS X 10.4 が返す IPv6 のアドレス表現が特殊(0.0.0.0)なので対処がされているようなのですが、10.6 ではまた少し違った表現(::ffff:0.0.0.0)を返すようになっているようです。Mac OS X 10.5 (Leopard)の環境は手元にないため未確認です。

以下の変更を加えて make test-all でこの Error がなくなること、他に Error が増えないことを確認しました。
