I tried to make this work a little while back; unfortunately G++'s object model seems to be incompatible with MSVC++'s, with the effect that only COM objects written in C can be compiled with G++.  I think this is due to the name mangling, but there is also a problem with exception handling.

     I have C++ COM DLL that compiles with both GNU/Cygwin
     and MSVC V6. I can call the function only when
     compiled with MSVC 6, however.

     I think this is because of the screwy private
     declaration in the Microsoft .DEF file. I never
     understood why that was required.

     Anyway, how do I acheive the equiv. effect with
     GNU/Cygwin C++? Does any one have a sample?

           Thanks,
                    Siegfried
