It's really unpleasant that we keep getting new attributes that we
seemingly are encouraged to use and get sent patches for it. And then we
learn a little later that that stuff isn't ready yet. It's annoying. I
know it isn't your fault but it would be wise to be a little more
careful. IOW, unless both clang and gcc do support that thing
appropriately don't send patches to various subsystems for this.

In any case, this is now fixed. I pulled an updated version from David.
