Just a note to this... this bug assumes that cbranchmode4 is _not_
implemented. If cbranchmode4 is not an optional standard name to implement
then this bug

I think cbranch is required in 4.5 where the cleanup happened. And yes we

Thanks Andy, was that documented anywhere? It would be interesting for me to
