I cannot connect the dots between size_type and the allocator.
The Container requirements  only states that size_type should be an
unsigned integer type large enough to contain any non-negative value of
difference_type. And difference_type comes from the iterator.
The AllocatorAwareContainer requirements do not mention size_type.
 Section [container.requirements.general] in the C++ standard.
