Problem with poll function


Hello

I've tried to build latest Curl on Cygwin and encountered problem reason of which is very nicely summarized on the following page

http://www.greenend.org.uk/rjk/2001/06/poll.html

It shows that behaviour of cygwin poll when socket is closed (fourth column in table) is only compatible with one old version of linux. Though curl developer probably will make workaround for this, maybe fix it also in Cygwin to avoid further problems. I've attached the patch for it.
