Leaving as P2.  

I'd like to have another think about this issue before 4.1.  However, I'm not
overly optimistic that we can find a good solution quickly.  

In looking at this example:

template <typename T_>
class C1
{
    typedef typename C2<T_>::T_PAR_TYPE T_PAR;
    struct S1
    {
        T_PAR par1;                       // #1
        typename C2<T_>::T_PAR_TYPE par2; // #2
    };
    ...
};

we might need to avoid using the same TYPENAME_TYPE node for TYPENAME_TYPEs
that are typedef'd and TYPENAME_TYPEs that are not.  Note that for "int", we do
have separate type nodes for all "int" typedefs, so we would in fact be able to
tell how we got at a particular typedef.

However, this may be another case of the more general problem that we don't
preserve enough information about how we obtained a type or declaration to do
full access-checking in template instantiations.

This issue will not be resolved in GCC 4.1.0; retargeted at GCC 4.1.1.

Will not be fixed in 4.1.1; adjust target milestone to 4.1.2.

Fixing this is simplified by DR 45:
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#45

Under DR 45, S1 now has all the access of its enclosing class.  We should be
able to just implement that DR and this problem will go away.
