The DJGPP sources are not yours; changing the license in any way is not
an option for you.  If you combined DJGPP sources with some other
sources that have a different license, you are limited to distributing
the combination under terms that comply with both licenses.

I'm not opposed to clarifying copying.dj to have the usual "or any later
version" text, though.  Note that such a change would still not give you
the right to change the license, just more flexibility in complying with
it.

Assume the version that is in COPYING and COPYING.LIB, included with
djgpp.  Versioning wasn't really an issue back then ;-)
