Synopsis: compilation problem with templates and inheritance

State-Changed-From-To: open->closed
State-Changed-By: lerdsuwa
State-Changed-When: Fri Aug 10 07:02:44 2001
State-Changed-Why:
    Not a bug.  g++ must be used instead of gcc in order for
    C++ library to be linked to the binary.  Try
    	g++ -o private private.cpp
