title: cannot run 'start' command from makefile in windows
body: <p>I am using gnu make 3.8.1 (mingw32) in Windows 7 operating system.
  I want to run 'start' command from makefile but it is giving some error. my syntax of command is-</p>
  
  <pre><code>start CMD /K http-server ./www -c-1
  </code></pre>
  
  <p>This command works when manually typed in cmd. It opens a new command prompt which runs the command 'http-server ./www -c-1', hosts the files present in www folder of current directory on port 8080 and shows the logs in the command prompt window it opened.
  but in makefile, it doesn't seems to work. My makefile is-</p>
  
  <pre><code>hostx:
      start CMD /K http-server ./www -c-1
  </code></pre>
  
  <p>There is more to the makefile but we only need to focus on this part.
  when i type 'make hostx' in cmd it shows the following output. 
  I am posting my cmd output as complete image so this is more clear</p>
