title: How to navigate to a directory in C:\ with Cygwin?
body: <p>I'm trying to install <a href="http://www.riverbankcomputing.com/software/pyqt/download" rel="noreferrer">PyQt4</a> so I can mess around with it. The installation guide said I had to install <a href="http://www.riverbankcomputing.com/software/sip/download" rel="noreferrer">Sip</a>. The last step to <a href="http://www.riverbankcomputing.com/static/Docs/sip4/installation.html#building" rel="noreferrer">installing Sip</a> is to use the <code>make install</code> command. Windows doesn't have that, so I looked it up and everything I saw said to install Cygwin. So I did. But...sip is in <code>C:\Python31\sip</code>.</p>
  
  <p>Can I run this from the Cygwin command? If so, how would I do that?</p>
  
  <p>Or can I run this from the normal windows command prompt?  If so, how would I go about that?</p>
