Informix Error -4005: You cannot redefine private base member function "name".

Cause and resolution

You cannot redefine private base member function "name".

This FUNCTION declaration in a class declaration names a member that is inherited from a base class of this class. However, that inherited name is declared as PRIVATE, so it cannot be overridden in this class. Review the declarations of all base classes; then choose a name for your function that will be unique to this class.
