 Because the FSF has copyright over a huge part of the XEmacs codebase. 
True, but let's not go overboard.  I don't see anything in the
GPL that precludes us from coding for non-free libraries as long
as we don't ship binaries containing those libraries.  We can
presumably ship stuff that dynamically links and we can ship
source distributions with no binaries.
