As already happens in this patchset, rename the other identifier. But this is C, we avoid these kinds of conflicts already because the language has no namespacing - it's going to be a pretty rare situtaion going forward. Most of the hooking that will be done is done with this patchset, and there was only one identifier that needed to be renamed.
