Yup. That's the right fix, and one of the ones I'd done to a local
tree, but never finished. Similarly with the formatting stuff. That
work is getting rather old, but might be useful. If you'd like I can
send it (I didn't even bother to try and compile it at the time).

It is likely that we'll start hacking this code to improve support
for low overhead loops on the c4x ports (good to see you cc'd Michael
Hayes).
