To eliminate this problem you could make the function:

code:

---

  int random_compare(int x, int y, int nx, int ny)

  {

    int x1 = x + nx*illwinter_dice();

    int y1 = y + ny*illwinter_dice();

    return (x1 - y1);

  }

---

and use comparison

code:

---

  if (0 > random_compare(x,y,2,2))

---

A nice idea, though it fails in the execution. 2d6 is not shorthand for two times the result of a d6, but for the openended result of rolling 2 d6'es (openended: sixes are rerolled and added potentially ad infinitum

Easy enough to modify, of course, though it makes for ugly code and only deals with inequalities. The order of evaluation problem can occur anywhere where two random calls are used within the same expression.
