>Description:
GCC currently accepts an invalid using declaration.

The first line marked with "// error" must not be accepted
because "org::gnu::gcc" is a namespace.

Warning: This information is based on my interpretation of http://anubis.dkuug.dk/jtc1/sc22/open/n2356

namespace org {
  namespace gnu {
    namespace gcc {
    }
  }
}

using org::gnu::gcc; // error - using declaration

using namespace org::gnu::gcc; // ok - using directive

class MyClass {
private:

  // the using declaration below is rejected as it should be
  // but for the wrong reason. the standard requires ANY
  // using declaration to be accepted as a member
  // declaration.
  // using org::gnu::gcc; // error - using declaration
};

int main() {
  return 0;
