Hi guys!

I am currently reviewing the license
of the dj64dev suite, and have a concerns
about the library code sources.
copying.dj states that the library-related
code is distributed under
"GNU Library General
   Public License, rather than the GNU GPL."

But the whole dj64dev suite is distributed
(by me) under GPLv3+. And the bigger
problem is that I ported the large chunks
of other GPLv3+ code into the library, so
now I need to clean up the mess.

I am trying to apply this "upgrade" procedure:
https://www.gnu.org/licenses/gpl-faq.en.html#v3HowToUpgrade
It says, among other things, that I need
to replace v2 with v3 in all sources, and
here is the problem: djgpp sources do not
list v2 or v3. They instead refer to copying.dj,
which explicitly forbids to modify these headings.
Also copying.dj doesn't state what version
of LGPL is that: is it v2+, or plain v2?
If it is plain v2, then the "upgrade procedure"
can't be applied. If it is v2+, then it is still
unclear how to apply the "upgrade" because
copying.dj explicitly forbids to modify itself. :)

So my questions are:
- What exactly version of LGPL does copying.dj mean?
- Can I upgrade it to LGPLv3+, and if so - how exactly,
   given that any modifications of the license info are forbidden?
