  It's not a part of C, but I guess it's possible a broken compiler might
not like us defining it, and it might get added to C in the future.
Neither of these is very likely, however.

  I would say define it, unless there's a known C compiler which has a
problem with it. Using bool is fine since it will be familiar to some
