TAutoObject: Builder 1.0 vs. 6.0

Code which builds under Borland C++ Builder 1.0 using TAutoObject as the ancestor class of a COM wrapper does not build under Borland C++ Builder 6.0. Does anyone know the work-around? Do I have to build the COM wrapper from scratch using the new wizard?

Can you put the object into a DLL in 1.0, and then link to it?

I don't have Borland C++ Builder 1.0. I know the executable was built with 1.0 using the source I have.
