According to the C++ language mapping (p1-137) the generated skeleton
classes should be directly or indirectly derived from 
PortableServer::ServantBase.

When you implement your servant class you can enable reference counting by
multiply inheriting from the RefCountServantBase mixin class.

For an example, have a look in src/examples/echo/eg1.cc:

class Echo_i : public POA_Echo,
               public PortableServer::RefCountServantBase
{
...
...
    // We allocate the object on the heap.  Since this is a reference
    // counted object, it will be deleted by the POA when it is no
    // longer needed.
    Echo_i* myecho = new Echo_i();

HTH,

David
