Any idea how come display-warning calls itself?

Note that if you will be distributing the *.eln files, I think the GPL
requires you to make the *.el files available.  In fact, this is so
even with the *.elc files.  So I'm not sure I understand how you could
distribute only the *.elc files until now: isn't that contrary to GPL?
