FWIW, I only put such Copyright notices on highly non-trivial code,
such as stat etc. (getdos_v.c was originally written for stat and
fstat).

It's up to the user (modulo the assignment papers that DJ might need).

Nothing, except fame (``I did that, see?'') and a right to claim that
they worked on DJGPP.  The real copyright is whatever COPYING.dj says.
