Hmm, my memory is not what it was, ... ;-) However, I seem to recall
that most of the changes were "improvements", with only a (relatively)

macros). (Oh, wait, I think 'unused' parameters etc., was another
problem area).

Yes, I've had that patch (and others like it) hanging around for
years! (perhaps it's time to dig through all those old branches)
