OK, company X writes a 50-Megabyte program the needs a sort routine.  The cost
of writing one is of course, trivial.  But the cost of a tiny modification to
one that comes with GNAT is even less.

Lawyers: "Wait! We don't want our code to be under the GPL!"

Programmer: "No problem.  See this special exception?"

Lawyers:    "OK, go ahead."

Zealous free software promoter: "Hey, when you distributed your program,
you distributed some GPL'd sort code.  You gotta tell me how to get a copy
of the source for that part."

Management: "#$^$^%%!  We saved a hundred dollars by re-using GNAT code,
now we have to spend a hundred dollars a week answering requests for the
source.  We'll never use any GNAT code again!"

Now if company X did NOT modify it, it's a different story.  They just
say, "Source code? Sure--we got it from
and you can, too!"
