I don't know about "your" allocator, but as far as libstdc++-v3 is 
concerned, I think all the containers can possibly support only C++98 
conforming allocators, or, maybe, C++0x conforming allocators (when 
-std=c++0x is used). Of course the pointer typedef can be non-trivial, 
that's the point. At this late stage I don't think we want to consider 
the possibility of a new, non-standard type, frankly. Maybe we could 
have done that say, 2-3 years ago, but given all the changes in the 
allocator chapter of C++0x isn't the right time to fiddle with something 
different yet. As a general policy, we want to concentrate on either the 
current or the new standard.
