Wait, wait... I am using both template members and template functions. Two
examples:

// constructor
template<typename D> SharedPtr( const SharedPtr<D>& ptr ) {
  share( ptr );
}

// operator
template<typename T, typename D>
bool operator==( const SharedPtr<T>& ptr1, const SharedPtr<D>& ptr2 ) {
  return ptr1.ptr() == ptr2.ptr();
}

They both work fine.

I am sorry for joining the conversation late. I will look back to catch up
on the thread and make some cohesive comments. But the below statement: "Ok
MS VC++6 does not support template function" does not seem correct.

Ok MS VC++6 does not support template function ( =
BOOST_NO_MEMBER_TEMPLATES).
So does it mean that the smart pointer library is useless in MS VC++6 or
there's any way to make it work ??
