State-Changed-Why:
confirmed. I think this is well-formed. [7.3.1.2]/3 seems
to be relevant. The question to answer is 'in the defintion of
N::A, what is the innermost enclosing namespace?'. Is it
'::' - that being the one that is 'open', or is it '::N'
- that being the one containing 'A'. It would be bizzare
if the answer was '::'.

System: Linux stoic 2.2.19 #1 Thu Apr 5 15:18:02 EST 2001 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-3.0/configure --prefix=/usr/local/opt/gcc-3.0
>Description:
Implicitly declaring a function through a friend declaration in a class
definition where the class and the function are members of the same
namespace doesn't compile.
>How-To-Repeat:
source that produces the bug:
// BEGIN: friendBug.cpp
namespace N
{
class A;
}
class N::A
{
friend void func(void);
};
void N::func(void)
{
}
int main()
{
return 0;
}
// END: friendBug.cpp
Compile with: gcc friendBug.cpp
gcc output:
friendBug.cpp:13: `void N::func()' should have been declared inside `N'
>Fix:
Workaround:
// BEGIN: friendFixed.cpp
namespace N
{
class A;
void func(void);
}
class N::A
{
friend void func(void);
};
void N::func(void)
{
}
int main()
{
return 0;
}
// END: friendFixed.cpp
