[Bug c++/14177] New: class forward declaration and typename are conflicting ?

["dfredoui at irisa dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

I don't really know if it is a bug or a strange feature of C++ ...
The problem is that the following code do not compile, which prevent to forward
declare some types without entering in the implementation of the class:

------------------------>>
struct Foo{
  // declaration part
  class foo1_t;// forward declaration of foo1_t
  class foo2_t;// forward declaration of foo2_t

  // implementation part
  class foo1_t{};// declaration of foo1_t (no problem)
  typedef foo1_t foo2_t;// declaration of foo2_t (do not compile)
};

<<------------------------

The error is the following:
>>------------------------
bug.cpp:8: duplicate nested type `Foo::foo2_t'
<<------------------------
