I'm hijacking this one just to refer to the existing code.

It would be interesting to know (or probably, remember) why this is
complaining if the initializer is smaller than required but not if
it's larger. Native _43 seems to report an error in both cases, maybe
older compilers didn't? Or maybe it's just wrong...
