title: Drush make - errors unzipping and distinguishing mime times
body: <p>I've installed Drush 5.8 on Windows 2008 R2 Enterprise, with all the options included except Remote Management.</p>
  
  <p>Whenever I run <code>drush make</code> I get errors about it not being able to unzip a github archive file, and unable to determine mime type for a js file.  Here is my make file and the output.  I'm not sure what is wrong here, and would love any pointers you may have.</p>
  
  <p><strong>Make file:</strong></p>
  
  <pre><code>; Drupal 7 core
