It seems that for C++0X, you must make the red-black-tree dependent
on Allocator, since you must use Allocator::pointer everywhere.
Or am I missing something?

Hi,
The iterator can depend on the Allocator::pointer but this doesn't forcerly means that it depends on the Allocator. If Allocator::pointer  is a typedef to a type idependent of Allocator the independency is ensured.

In addition we could make iterator depend on Allocator::void_pointer and use pointer_traits<>::rebind.

Am I missing something?

Best,
Vicente
