title: What is the difference between gmake and make?
body: <p>I am trying to understand the difference between 'gmake' and 'make'?  </p>
  
  <p>On my linux box they are identical:</p>
  
  <pre><code>% gmake --version
  GNU Make 3.81

  <p>I am guessing this isn't the same on all platforms?
  Is there a good reason to use one over the other?<br>
  Is there some historical significance to why there are the two names?</p>
