Just realised that that last example is bogus, it should read:

  inline int const *makedep(int const *a, ...) { return a; }  // variadic

  int f3(int const *p, int const *q) {
    int flag = *p;
    return flag ? *makedep(q, flag) : 0;
  }

In C++, makedep could be a template - the counterpart of kill_dependency.
