The problem with the deque is simple: in deque.h you just make the
destructror deque::~deque defined inline and all is well.(I think the
problem is really in the defines or something).

The whole point of container-adoptors is that they can only be used
on containers, but a stack class is not so very difficult to code
yourself. In fact most books I have seen on C++ have one in one
of the first chapters. For instance you can simply make a template
class of the example of Lippman's on page 88 ev.
The difference between the container-adaptor and your own then is
however that you need to do memory allocation yourself(Lippmans
example makes use of a constant stacksize).

Heh ?? Make your own container ?? Is that possible ? If so how would
you start( is there some baseclass container ??).
