[Bug c++/22136] New: [4.1 regression] Rejects old-style using declaration

["bangerth at dealii dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This used to compile but doesn't any more on mainline (ok on 4.0.x branch): 
----------------------- 
struct B { 
    void foo(); 
}; 
 
template <typename T> class I : public B {}; 
 
template <typename T> class D : private I<T> { 
    I<T>::B::foo; 
}; 
--------------------------

g/x> /home/bangerth/bin/gcc-4.1-pre/bin/c++ -c x.cc 
x.cc:8: error: type &#8216;B&#8217; is not a base type for type &#8216;D<T>&#8217;
