Unfortunately, it doesn't work on Intel Linux in strict mode, it just 
gives 0 every time.

If I understand the problem correctly (and I'm not sure that I do), the 
declaration of unique_id_helper that you want to find is inside 
unique_id_impl<T>::declare_friend<Tag> which is neither in scope, or 
subject to ADL, when it is 'called' in unique_id_impl<T>::unmarked<Tag, 
N>. So only the 'no_type' declaration in boost::detail is found.

I hope that makes sense.
