make: *** [useezptr.o] Error 1

intention: I was trying to allow my casting operator

template<typename itemType>
template<typename itemType2>
extern
ezptr<itemType>::
operator ezptr<itemType2>( void ) const
{
	ezptr<itemType2> return_value;
        ezptr<itemType> temp( *this );

	::swap( dynamic_cast<itemType2*>( temp.rep_ ), 
		return_value.rep_ );
        ::swap( temp.num_refs_, return_value.num_refs_ );
// ...other members
	return return_value;
}

to have access to the 'private' data members for deep-copying.  I've
accomplished this before about a year ago using gcc on the same system on
another project that used class templates.  Any help is appreciated.  I
apologize if the solution is trivial, I tried to find the answer using
newsgroups first.  Please, do not post any of this code _anywhere_.
