title: How to prevent Closure Compiler from renaming "true", "false" and "null"
body: <p>Google Closure Compiler renames all "true", "false" and "null" occurences in code like;</p>
  
  <pre><code>var s = true, x = null, V = false;
  </code></pre>
  
  <p>and uses these shorthands instead; in conditions such as;</p>
  
  <pre><code>if (someVariable == s)
  </code></pre>
  
  <p>now; Google Analytics code defines it's own "s" variable; overriding the value "true"; and as you can see this causes a lot of problems.</p>
  
  <p>I don't want to change GA code; I just want Closure Compiler to quit renaming true etc. Externs do not work.</p>
  
  <p>Do you know any way to accomplish this?</p>
