[Bug c++/23211] New: using dec in nested class doesn't import name

[igodard at pacbell dot net]

template<typename T>
struct  foo {
    typedef int itype;
    typedef int jtype;
    struct bar {
        typedef typename foo::itype itype;
        using foo::jtype;
        itype i;
        jtype j;
        };
    };

gets you:
~/ootbc/members/src$ g++ foo.cc
foo.cc:9: error: `jtype' does not name a type

Adding "typename" here and there changes the error you get but doesn't compile.
The above code compiles OK on Comeau.

I think this is a dup of bug 14258.  GCC still implements the old using rules.

Confirmed. This is a regression against 3.3 which compiled the code 
just fine.

As I said, I think this is a dup of bug 14258, we never really got using correct.

I'm not sure it is a duplicate, since the error messages are very 
different. But be that as it may, this is a regression and should 
be fixed. If it is, someone may want to take a look at that other 
PR as well.

So this is just a diagnostic issue and not a regression.

Not, it's an error: invalid text is accepted without diagnostic (if the
identifier introduced with the "using" is not itself used, then the using
statement is invalid but gets no diagnostic).

    instead of dependent_type_p, to check that a non-dependent
    nested-name-specifier of a class-scope using declaration refers to
    a base, even if the current scope is dependent.
