#include <stdio.h>


class C {

  struct A;
  struct B {
    int i;
    A * a;//compilation error is here on "A" letter
  };

  struct A {
    int j;
  };

};


void main() {
  int i, j;
  scanf("%d %d", &i, &j);
  printf("%d", i+j);
}


this causes compilation error. But everything is
allowed by C++ standart and compiled properly in MSVS.Net
2003 and Borland C++ Builder.

Admins, please check and fix that.
