The following is accepted by clang++, but rejected by g++ and icpc as an
ambiguous reference as both 'int a' and 'template<T> a' are in the global

namespace A {
template<typename T> struct a { };

using namespace A;
int a;

/* a<int> should be an ambiguous reference */
a<int> b;

clang++ -v
clang version 2.0 (trunk 103456)
