[Bug c++/15075] New: "using namespace" fails in part

[gcc-bugzilla at gcc dot gnu dot org]

"using namespace Test;" fails to tell the compiler that a friendly
function definition is within Test.  "namespace Test {...}" works fine.

Environment:
System: SunOS bioquad 5.9 Generic_112233-11 sun4u sparc SUNW,Sun-Fire-V440
Architecture: sun4

	
host: sparc-sun-solaris2.9
build: sparc-sun-solaris2.9
target: sparc-sun-solaris2.9
configured with: ../../../distribution/gcc-3.3.2/configure --prefix=/local/bioproj/people/lnewberg/install/sparc-sun-solaris2.9/gcc-3.3.2 --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as --disable-nls --enable-languages=c,c++,objc

How-To-Repeat:
	Compile with g++ -c test2.cc
--- Begin test2.cc ---
// This file does not compile under g++.  I think it should.  See
// below.

namespace Test
{
    class A
    {
    private:
	class B
	{
	public:
	    int _b;
	};
	friend bool works1(B const &);
	friend bool works2(B const &);
	friend bool fails(B const &);
    };
} // End of namespace Test

namespace Test
{
    bool works1(A::B const &lhs)
    {
	return true;
    }
} // End of namespace Test

using namespace Test;

// Despite the "using namespace Test" directive, the function fails()
// must be declared as "Test::fails" rather than simply "fails" or the
// compiler complains that class Test::A::B is private in this
// context.
// 
// Note that the "using" directive does work to eliminate the need to
// use the explicit Test::A::B instead of the shorter A::B in the
// definition of fails() below.
// 
// Contrastingly, the functions works1(), above, and works2(), below,
// compile without error.

bool Test::works2(A::B const &)
{
    return true;
}

bool fails(A::B const &)
{
    return true;
}
--- End test2.cc ---

Fix:
	Use "namespace Test {...}" instead.
