A bug report for ftpcopy came in today: ftpcopy doesn't work over socks5 using runsocks. After a little bit of investigating it turned out that the socks5 library includes a wrapper for select(). This wrapper sets some flag if a non-blocking socket is connected now. Later this flag is needed inside the getpeername() wrapper.
Now there's no such wrapper for poll. Impact: Bang. Connect failed. No, not really, but ftpcopy couldn't tell.

I'll include some way to turn of the usage of poll at compiletime. The clean solution would be to fix socks5, but i don't really like the nec peoples copyright, and i don't like the code. Somebody forgot KISS.
Besides, what's socks good for? Isn't it just an excuse for not using the right firewall?
