Actually, if you have an allocator a of type A for objects of type T, you can
get the corresponding allocator b of type B for objects of type U by:

typedef typename A::template rebind<U>::other B;
B b(a);

@Martin: what do you mean by "The container has an allocator for the abstract
base type"?  The part "allocator for an abstract base class" sounds wrong to
me since no whole object can be of an abstract class, and thus you can't
allocate such objects.
