Yes, indeed. I misread your initial email. Anyway, here a summary of
the licenses of the libraries linked to the GTK+ version of Emacs. All
GPL-like licenses had the "or later version" clause. Most modified MIT
X11 licenses, just have a notice similar to the following added:

   Except as contained in this notice, the name(s) of the above
   copyright holders shall not be used in advertising or otherwise
   to promote the sale, use or other dealings in this Software
   without prior written authorization.

I attached the small script, I used, to check the licenses quickly of
the libraries on a Debian-based system.
