Synopsis: using declaration accepted as using directive

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Fri Dec 20 19:13:09 2002
State-Changed-Why:
    Confirmed. Short testcase:
    ---------------
    namespace gnu {
      namespace gcc {
      }
    }
    using gnu::gcc;
    ------------
    This should be rejected, but is not.
    
    Regarding your other problem: this is what gcc3.4
    and icc7 say:
    tmp/g> /home/bangerth/bin/gcc-3.4-CVS/bin/c++ -c x.cc
    x.cc:6: error: using-declaration for non-member at class scope
    tmp/g> icc -c x.cc
    x.cc(6): error: a class-qualified name is required
          using gnu::gcc;
                ^
    I think they both say the same, but in different words,
    so I'd say this is ok. However, this doesn't touch the
    problem above.

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;
