Access to private types in a class from another instantiated template class is
not getting the expected "type is private" error from gcc compiler.

inp4.cpp:1: error: 'typedef int A::type' is private
inp4.cpp:6: error: within this context
$cat inp4.cpp
class A { typedef int type; };
template<typename T> class B { typedef A::type type; /* no error. */ };
B<void> b;
class C { typedef A::type type; /* error thrown. */ };
Note: Though I tested this with 4.3.1 gcc I think the problem should be present
in 4.4.0 as well because the changes document does not state anything related
to this bu.
Please get back as quicly as possible.
