Error with default arguments?

["Jan D." <jan dot djarv at mbox200 dot swipnet dot se>]

Hello.

Using egcs 971122 on Linux 2.1.59, libc 2.0.5.

This is taken straight from the November 1996 working paper for C++:

/*
6 The  default  arguments  in  a member function definition that appears
  outside of the class definition are added to the set of default  argu-
  ments provided by the member function declaration in the class defini-
  tion.  [Example:
*/
          class C {
                  void f(int i = 3);
                  void g(int i, int j = 99);
          };
          void C::f(int i = 3) // error: default argument already
          { }                  // specified in class scope
          void C::g(int i = 88, int j) // in this translation unit,
          { }                          // C::g can be called with no argument
//   --end example]

Compiling however does not produce an error:

If -pedantic is removed, only the first warning is issued.
I don't have access to the final ISO C++ so this may have changed.  If
not the example should not compile.
