--- Comment #9 from Andrey Belevantsev <abel at gcc dot gnu.org> ---
Another test case of the same issue (both clang and icc compile this fine):

namespace ns {
  class Base {
  public:
    int i;
  };
  class Derived : public Base {
    using Base::i;
  };
}
class DerivedDerived : public ns::Derived {
  using ns::Base::i;
};

we get

/tmp/ns.C:4:9: error: ‘int ns::Base::i’ is inaccessible
/tmp/ns.C:10:7: error: within this context

It is indeed rejects-valid but I cannot claim this is a regression as I can't
find the version that did that correctly.  It's 9 years of the original
bugreport, maybe rise a priority?..
