I wouldn't have expected bitfield type to be "visible" outside of its
structure.
And I failed to comprehend how unsigned long int:48 can be passed to a variadic
function without being promoted to plain unsigned long int ...
Anyway, I will have to add a cast to silence the warning.

AFAICT, there's no unsigned long long involved in my example.
