That's false, because this specific macro don't force any types, it
only passes types through as-is to type-checked functions, so both
the macro and the function variant does similar quality of type
checking ...

But I'm fine with both approaches, I suggested a macro because the
existing rdtsc definitions used macros already - but I have no
strong feelings which particular color this shed gets painted ...

Thanks,
