Except when - you never release the application since you're using it only internally in your office or so. That's the trivial case. - you purchase a special Cygwin license from Red Hat. For a one time fee per project you may distribute also proprietary software linked against Cygwin. Visit http://www.redhat.com/products/support/cygwin/ for more information.
