One comment: Your answer depends that the code is compiled with g++.
If the code is compiled with a different c++ compiler, you can 
generally not expect it to be compatible with neither g++ nor
GNAT c++ interfacing. The reason is that c++ compilers have  
different name mangling schemes. If your library is compiled with say 
Sun CC, you can't link it with GNAT c++ interface. If your library
is i binary form or not is possible to compile with g++, you
must use C conventions from both the Ada and c++ side.
