This means that code which compares two char-po<strong>in</strong>ters (each<br />
po<strong>in</strong>t<strong>in</strong>g to one of <strong>the</strong>m) should not assume one is before <strong>the</strong> o<strong>the</strong>r.<br />
In struct { <strong>in</strong>t a, b; } c; <strong>in</strong>t* p = &c.a; <strong>in</strong>t* q = &c.b;<br />
we know that p < q, s<strong>in</strong>ce a is declared before b.<br />
