As long as your proprietary application is not load-time or run-time
linked against the Cygwin DLL, or against any other GPL'd library, then
you should be fine by distributing the sources of all open-sourced stuff
in your package.

However, IANAL, so if you want to be on the real safe side, contact a
lawyer which is specialized in licensing issues, or use one of the
official Red Hat contacts given on the http://cygwin.com/licensing.html
web page.

P.S.: A simpler option is to use a Windows native GNU zip, which takes
the Cygwin DLL out of the equation.
