[Bug c++/26752] New: Name lookup ambiguity with namespace

["gccbug at gammarayburst dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The following code snippet:

struct B {};
void A(B) {};

namespace N {
void A(B) {}
void f(B b) {A(b);}
}

gives this error (tested with 3.3.6 and 4.0.3):

namespaceconf.cpp: In function 'void N::f()':
namespaceconf.cpp:6: error: call of overloaded 'A(B&)' is ambiguous
namespaceconf.cpp:5: note: candidates are: void N::A(const B&)
namespaceconf.cpp:2: note:                 void A(const B&)

I think it should compile and use N::A() and ignore ::A() according to 3.4.1 1,
6.

Can be worked around by qualifiying the call to A as N::A(b);
