How best to do this?
In a word or two, don't. This is basic OOP: all accesses to an object should
be via its (possibly virtual) member functions. There's nothing to stop you
from defining
virtual Dog_t Base_t::as_dog() { return nullptr; }
in the base class, and overriding it as
virtual Dog_t Dog_t::as_dog() { return this; }
in the derived class. If you really need to...
Can I remind you that this list is for specific GCC help, not C++ language issues?
Thanks.
