In any case, I had to apply a patch on my tree fixing it. PS: I noticed the compilation breakage too late to merge the fix together with your patch - my background compilation process was supposed to not only print a warning message in red, but also to bug me at the speakers - due to Murphy laws, everything got wrong: the screen was overlapped by another one; my speakers were muted). Still, I can swap the patch order for the patches I didn't sent upstream yet, in order to put the fixup patch just after yours.
