// Bug 75. using declarations cannot introduce functions which ambiguate
// those in the current namespace, BUT here we're reaccessing the current
// namespace -- the function is not being 'introduced'.
extern int a();
struct x {};
using ::x;
using ::a;
extern "C" void foo ();
namespace {
extern "C" int foo ();
using ::foo; // ERROR - already in use
}
