Not yet, but the fix will be in the next Cygwin release. The problem is that the conversion from a Winsock error to the corresponding POSIX error code is accidentally called twice in the getsockopt(SO_ERROR) case. However, even with this fix, you might not get EHOSTUNREACH either. In my testing, the error returned by the underlying Winsock getsockopt function is not WSAEHOSTUNREACH, but WSAETIMEDOUT. This will be translated into ETIMEDOUT == "Connection timed out". Thanks for the testcase!
