Whatever you want to call it is fine. I prefer to think that GPL'd software that incorporates Open Source takes a copy and makes it GPL (especially because if I modify the Open Source at all, my changes are not available under an Open Source license.) Other people who are using that piece of Open Source are not using my copy, which is GPL.
