title: Eclipse CDT does not find either Cygwin or MinGW toolchain
body: <p>I am having hard times to configure Eclipse Juno to for C/C++. I am a Windows user, so I have installed <code>Cygwin</code> and <code>MinGW</code>, and <code>CDT</code> under Eclipse. Also configured the <code>PATH</code> variable correctly, though I still do not have any new toolchain in Eclipse C/C++ new project.</p>
  
  <p>These are my Eclipse details:</p>
  
  <pre><code>Eclipse Java EE IDE for Web Developers.
  
  Version: Juno Release
  Build id: 20120614-1722
  </code></pre>
  
  <p>Also, see image of installed component of Eclipse.
