// 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; // { dg-error "" } already in use
}
