These are two different things.  If you change `printf', put it back
into the library and use that library, it makes your changed DJGPP
libc LGPL, AFAIK.  `djtar' is already GPL (look into its sources), but
even if you use code from programs that don't specifically say they
are GPL, what you get after changing it is GPL code.

In general, DJGPP's copyright is GPL with certain restrictions lifted,
but the more lenient terms hold *only* if you do not change the DJGPP
sources.  For example, you are entitled to distributed binaries
without sources *if* you haven't changed the sources.

Anyway, I'd suggest to ask DJ about these fine details.  The copyright
is his, so he is the definitive authority on these issues.  The FAQ
only describes the usual cases and its language isn't legalistic
enough (that's intentional, btw).
