I didn't say exclusively.  I said stdio.h provides it.  Headers that
expect stdio.h to *relinquish* its provision of NULL are broken.  The
other djgpp headers that also provide NULL cooperate so that none of
them have to relinquish their provisions to the others.

They all define it to exactly the same thing: 0
