Yeah, something like that. I am sure glibc would not change the constants going forwards. I am only looking for cases where we got the hard-coded value wrong for some reason; so a mechanical check would make sure we did not. Again, this is not worth doing here. It would probably be some sort of macro like `MAKE_SURE_IS_DEFINED_BUT_THINK_OF_BETTER_NAME_FOR_THIS_MACRO(name, value)` that would encapsulate both defined/undefined paths.
