The code is correct.

That is possible, the above is the way to go.

This problem seems to be caused by the conjunction use of namespace.
I was able to get g++-2.95.2 grok it without problem when rc_ptr is
defined iin the global namespace.

Current CVS accept your original code without problem, so I guess the
problem was fixed.
