Problem with ostream_iterator

[Chan Shih-Ping]

System: gcc-2.95.2/libstdc++-2.90.7 with --enable-namespaces

The following ostream_iterator code does not
compile with -fhonor-std


//Code taken from testsuite multiset.cc
//Define operator<< for pairs

std::ostream&
operator<<(std::ostream& os, const std::pair<int, int>& p)
{
  return os << p.first << ' ' << p.second;
}

main()
{
	std::pair<int, int> p(12,34);
	//this compiles and works
	std::cout << p << std::endl;


	std::ostream_iterator<pair<int, int> > out(std::cout, "\n");

	//This fails to compile: why?
	//The complaint by the compiler is 
	//not being able to find the function
	//std::ostream& operator<<(std::ostream&, const pair<int, int>&)
	//which is defined above
	*out = p;


}
