Agreed, I've convinced myself that `int` is really the only currently used 
example (including the CMake tests, which are particularly troublesome to me), 
and that we should continue supporting it without diagnostic (again, because 
CMake).  Everything else is either problematic due to calling-convention issues 
or at least not used.

So I'm OK with this being a breaking-change error except for `int`.  We've also 
agreed that `unsigned` makes sense as well because 'why not'.
