[Bug c++/25427] Impossible to create a friend function for a class in a namespace, outside the namespace.

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2005-12-15 16:23 -------
This is invalid code, Comeau gives the following error:
"ComeauTest.c", line 12: error: the global scope has no "operator<<"
                        friend std::ostream & :: operator<<(std::ostream &os,A
&a);
                                                 ^
GCC's error could be better.

Anyways the way to fix it would to add the following before the namespace S:
namespace S{class A;}
std::ostream &operator<<(std::ostream &os,S::A &a);
