>Description:
One can construct template objects of kind
"template <class T> dummy:basedummy<T>", but if one tries to
cast a dummy<whatever> pointer to a basedummy<whatever>
pointer ("whatever" an instantiation of the template), the
compiler does not recognize basedummy<whatever> to be a base
class of dummy<whatever>.
