Also, most of the stuff I've been fixing is ancient code of the form

   for (ptr = array; ptr < &array[max]; ptr++) { ... }

which is worth tidying up but not incorrect. While I've run across a
couple bugs in nearby code, I haven't seen a true positive from the
warning yet. Given that src/games contains a much of the oldest and
cruftiest code in the tree, I think that's a sign it's not worth
dealing with until gcc gets smarter.
