Use poll as a reasonably portable implementation. This takes advantage of the existing FAKE_POLL implementation as well. getsockopt(SO_ERROR) on Windows uses "int", removing the requirement for any custom code for that platform. We don't add any handling for EINTR, since it would add considerably more code, and the connection can simply be retried. For that reason, poll returning -1 is always an error.

There was a problem hiding this comment.
One thing to note, which I don't know if it's relevant, is that any timeouts below 1ms will be rounded down to 0, causing poll to return immediately.
I don't think anyone actually would have such strict timeout requirements, though.
