I now looked at the cygwin code and found the error. I currently compile 
a new cygwin1.dll. So if you're already working on it, you can wait until
I released the patch.

The problem is that cygwin searches for all interfaces and the searches 
the matching IP. The correct order is to search for all IPs and the search 
the interfaces for it. 

The current code does not produce exactly the same output as linux does
(linux returns eth0, eth0:1, eth0:2 for different IPs on one device, the
 modifed cygwin code returns eth0, eth1, eth2 ... ) but It atleast works.
