problem with: namespace N { class N {...}; }

[Alexander Zvyagin]

Dear GCC developers,

I have this code (and I hope it is correct C++ code):

class A {};
namespace N
{
  class B { friend A operator>>(A,B); };   // -B-
  class N { friend A operator>>(A,N); };   // -N-
}  
A N::operator>>(A, N::B) { return A(); }   // -B-
A N::operator>>(A, N::N) { return A(); }   // -N-

$ g++ -c a1.c
a1.c:7: type specifier omitted for parameter
a1.c:7: `N::operator >>(A)' should have been declared inside `N'
a1.c:7: `N::operator >>(A)' must take exactly two arguments

If you remove lines marked with -B- or with -N- then gcc will compile the
code.

The same problem exists with this code (try to remove marked lines):

class A {};
namespace N
{
  class B {};  void f(B); // -B-
  class N {};  void f(N); // -N-
}  
void N::f(N::B) {}   // -B-
void N::f(N::N) {}   // -N-

$ g++ -c a2.c
a2.c:7: `B' is not a member of type `N::N'
a2.c:7: variable or field `f' declared void
a2.c:7: `int N::f' redeclared as different kind of symbol
a2.c:5: previous declaration of `void N::f(N::N)'
a2.c:7: syntax error before `{'

I use gcc version 2.95.2 19991024 (release).

With best wishes,
Alexander Zvyagin.
