Bug (?) in namespaces and overloading resolution

[njs3 at doc dot ic dot ac dot uk (Niall Smart)]

Hi,

The following code does not compile on 19980604, I believe it should.
It works if the defintion of struct X is moved into namespace B.
The error messages reported are:

egcs/njs3-bug-9.cc: In function `struct C::Y & operator <<<A::X>(struct C::Y &, const struct A::X &)':
egcs/njs3-bug-9.cc:43:   instantiated from here

egcs/njs3-bug-9.cc:26:                 operator <<<A::X>(C::Y &, const A::X &)

Please CC me on any response, thanks.


#include <iostream.h>

using namespace std;

namespace A {
	struct X { };	
}

namespace B {

	using A::X;

	inline ostream& operator<<(ostream& ostr, const X& x)
	{
		return ostr;
	}
	
};

namespace C {

	struct Y { };
	
	template<class T>
	Y& operator<<(Y& y, const T& t)
	{
		cerr << t;
		return y;
	}
	
};

using namespace B;
using namespace C;


int
main()
{
	X	x;
	Y	y;
	
	y << x;
}
