#10672: std::iterator_traits<boost::unordered_map<K,M>::iterator>::pointer should
be value_type*, not detail::ptr_node<...>

Milestone:  To Be Determined  |  Component:  unordered

------------------------------+-------------------------
 The iterator type looks like:

 template <typename NodePointer, typename Value>
 struct iterator
     : public boost::iterator<
         std::forward_iterator_tag, Value, std::ptrdiff_t,
         NodePointer, Value&>

 The NodePointer argument here (which is
 boost::unordered::detail::ptr_node<...>) becomes the
 iterator_traits<>::pointer type.

 But iterator's operator->() returns Value *:

 Value* operator->() const {
     return &node_->value();
 }

 Seems like this should be changed.
