Unfortunately, the license used in these files contains the "advertising
clause" that is incompatible with the GPL.  The copyright notice and the
permission notice must appear not only in the code, but also in the
supporting documentation (help pages, GIMP manual, whatever).  This
extends to any derivative works, so this is not compatible with the GPL
because anyone re-using this code for any purpose would be required to
add these notices in the code and in the documentation.  The GPL does
not allow that kind of restrictions: "You may not impose any further
restrictions on the recipients' exercise of the rights granted herein."

Another problem is that the GIMP (the whole package, not only the core)
is usually advertised as being released under the GPL (or GPL + LGPL).
This is what is mentioned on our home page (www.gimp.org) and this is
what appears in most binary distributions.  This is stated for example
in gimp.spec.in, which creates gimp.spec for RPM distros.

The GPL cannot be applied to the whole package, because of the problems
mentioned above.  So we have to change the license for the source
tarball and try to inform those who build binary packages, or stop
distributing the files that are not GPL-compatible.

Reminder: the corresponding report in our Bugzilla is:
