win32 support

[gugod]

Should we support win32 platform in some way? Lets have some discussion.

I took a quick look:

This makes non-live test to pass (no idea about the logic in there):

•        if ($nfound != 1 || (defined($read_timeout) && $read_timeout <= 0));
  

•        if ($nfound != 1 && (defined($read_timeout) && $read_timeout <= 0));
  

live test is another issue though. IO::Socket::INET->new(Blocking => 0 ) can be used instead of the low level api but it needs further work as some other parts need changing as well.
