Ok we now know that the problem lies in ssh, not in expect, neither
cygwin. Time for you to start digging in the ssh-sourcecode or
similar, as Corinna said, you just need to modify it so it reads from
stdin instead of /dev/tty or whatever.. 

Another alternative might be using authorized keys as I mentioned,
thats a little stronger than 'no password'. 

ssh-agent might also be interesting..
