title: In what order prerequisites will be made by the GNU make?
body: <p>Assuming we have the rule:</p>
  
  <pre><code>a: b c d e
  </code></pre>
  
  <p>and <code>b</code>, <code>c</code>, <code>d</code> and <code>e</code> are independent of each other.</p>
  
  <p>Is the order of making <code>b</code>, <code>c</code>, <code>d</code>, <code>e</code> defined? It seems that generally they will be made in order <code>b</code>, <code>c</code>, <code>d</code>, <code>e</code>, but may it sometimes happen, that the order will be different?</p>
