>Description:
The following used to compile (and does so with icc7, for
example, in strict ANSI conformance mode):
---------------------------
template <class T> class Outer {
  private:
    struct Inner {};

    template <class T_>
    friend typename Outer<T_>::Inner foo ();
};

template <class T>
typename Outer<T>::Inner
foo () {
  return Outer<T>::Inner();
}

void f() {
  foo<int>();
}
-----------------------------

It fails since yesterday:
tmp/g> /home/bangerth/bin/gcc-3.4-CVS/bin/c++ -c x.cc
x.cc: In function `void f()':
x.cc:3: error: `struct Outer<int>::Inner' is private
x.cc:16: error: within this context
x.cc:3: error: `struct Outer<int>::Inner' is private
x.cc:16: error: within this context
x.cc:3: error: `struct Outer<int>::Inner' is private
x.cc:11: error: within this context
x.cc: At global scope:
x.cc: In instantiation of `typename Outer<T>::Inner foo() [with T = int]':
x.cc:16:   instantiated from here
x.cc:3: error: `struct Outer<int>::Inner' is private
x.cc:11: error: within this context
x.cc:3: error: `struct Outer<int>::Inner' is private
x.cc:11: error: within this context

Kriang, I think that one of your patches yesterday must
have caused this, since our nightly builds went fine
until this night. Could you take a look at it?

Thanks
