Taking this bug.  The code

  void N::func(void)

is rejected because the declaration

  friend void func(void);

doesn't declare 'func' inside namespace 'N'.
A separate declaration is necessary before the
qualified ID form 'N::func' can be used.  The 
following code, compiles under como, confirmed
the above idea.

namespace N
{
  class A;
}

class N::A
{
  void x();
  friend void func(void);
};

namespace N
{
  void func(void); // declare func
}

void N::func(void) // after declaration
                   // can now defined using qualified name
{
  N::A a;
  a.x();  // access private function
}

int main()
{
  return 0;
}

The bug will be fixed when problematic codes in libjava
(it assumes friends are in '::') are corrected.
