Great. Thus I'm going ahead and committing the patch to fix the regression.

Indeed, you are totally right. But I'd rather work on that as a followup 
patch (maybe with Sebastian' help?) because it doesn't seem completely 
trivial: I'm mostly worried by the existing uses of abs_hwi *inside* 
hwint.c itself not but those two remaining instances outside of it 
(which would be possible to replace immediately).

Paolo.
