Oh! Hmm ... I think I jumped to conclusions when the part of my patch
that touched struct RBTreeIterator failed to apply. But you're right,
rb_iterate has been there since 9.0 now that I look more carefully.
So we really ought to back-patch further. However:

Yeah, I'm now mighty confused about this as well. PL/Ruby is pretty old
too, so how come nobody noticed this before? Is its rb_iterate call in
someplace that hardly gets any use?
