I'd be OK with '%1$d' syntax.
That leaves type safety as the main problem. Your solution involving
_Generic is interesting -- I didn't even know that existed. I don't
think it needs to be supported on all compilers, as long as we are
getting errors from somewhere. They would be runtime errors instead of
compile-time errors, though.
