Thread model: single
gcc version 3.4 20030413 (experimental)
>Description:
GCC 3.4 does not compile the following legal snippet:

---------------------------------
template <typename T>
struct Foo
{
    template <typename Q>
    struct Inner
    {
        typedef int type;
    };
};

struct Bar
{
    template <typename A>
    void func(void)
    {
        typedef typename
            Foo<int>
            ::Inner<int>
            ::type type;
    }
};

int main()
{
    Bar b;
    b.func<int>();
}
---------------------------------
newbug.cpp: In member function `void Bar::func()':
newbug.cpp:19: error: no type named `type' in `struct Foo<int>::Inner<int>'
newbug.cpp:19: error: ISO C++ forbids declaration of `type' with no type


I also tried adding the nested template keyword (which is unneeded because the postfix-expression is clearly non-dependent) but it does not help.

Previous GCCs compile the above correctly.
>How-To-Repeat:
Compile the snippet

No known workaround
