--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Still present on trunk. Clang and EDG emit the definition of func. No version
of GCC I tested (back to 4.3.6) does.

Slightly reduced:

struct A
{
  friend void func() { }
};

int main()
{
  void func();

  func();   //linker error undefined reference to `func()'
}
