Don't take the following question as a dig at GNU. I'm a satisfied
customer. I've used GNU-emacs for over four years. It's now the only
editor I feel really comfortable with.  I ask the following for
information only...

A while back, I remember some kind of discussion over the copyright
notice on BISON.  Do I recall that if you compile it into a program --
a command-interpretter for example, the program is supposed to
advertise BISON when it comes up? Or an I dreaming?
I also seem to remember some question over whether any program
which was prepared using BISON could be shipped without all the
GNU baggage, because FSF copyrights the object code resulting
from compiling the parser-procedure.

I never did hear the last word on it. Can some gnuguru enlighten us?
