While it's possible Cygwin is breaking something here, I'd first verify 
that you're not exceeding the underlying stack's capabilities.  See the 
Winsock Programmer's FAQ, item 4.1:

	http://tangentsoft.net/wskfaq/advanced.html#rawsocket

It happens that I'm back to working on the FAQ again, so if you learn 
anything about raw sockets that you think should go in the FAQ, let me 
know.  Off-list, of course.
