--- Comment #7 from Arthur O'Dwyer <arthur.j.odwyer at gmail dot com> --- @David, sadly, I'm not set up to build or test GCC patches, nor am I registered as a contributor. Anyone else want to step up? I could suggest test cases, perhaps, but I wouldn't be good at shepherding this patch all the way through the process-I've-never-done-before.
