Hmm...  Here's a theory:

Since ostream_iterator is defined in namespace std, the context in
which the expression that outputs a pair to the ostream is that
namespace, where a number of operator<<s that hide the definition in
the global namespace exist.  Since the argumetns have type
std::ostream and std::pair<int,int>, Koenig lookup only searches
namespace std too.  So, the definition of ::operator<< isn't
considered.  Does this make sense to anyone?
