Drush make - errors unzipping and distinguishing mime times

Question

I've installed Drush 5.8 on Windows 2008 R2 Enterprise, with all the options included except Remote Management.

Whenever I run drush make 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.

Make file:

; Drupal 7 core
core = 7.x
api = 2
projects[drupal][version] = 7

; Libraries
; --------

libraries[colorbox][download][type] = "get"
libraries[colorbox][download][url] = "https://github.com/jackmoore/colorbox/archive/1.4.8.zip"
libraries[colorbox][directory_name] = colorbox
libraries[colorbox][destination] = libraries

libraries[zepto][download][type] = "get"
libraries[zepto][download][url] = "http://zeptojs.com/zepto.min.js"
libraries[zepto][directory_name] = zepto
libraries[zepto][destination] = libraries

Output:

Answer 1

Finally got it figured out after a lot of struggle.

Using Cygwin I was able to get a copy of unzip, which I put in the Program Files (x86)\Drush\GnuWin32\bin directory (which is in my PATH environment variable). This cleared up the errors listed about unzip.

As for the mime-type issue, I had to manually edit includes/drush.inc to add '.js' => 'application/javascript' to the $extension_mimetype array. See http://drupal.org/node/1825946 for the discussion that led me to this.
