title: Compiling Error: unable to open include file
body: <p>I'm working on xinu and I've changed some <code>*.c</code> files: <code>resched</code>, <code>create</code>, <code>initiali</code>, <code>clkint</code>. I have also created a header file called <code>newheader.h</code> and included it in the source files above like this</p>
  
  <pre><code>#include "hewheader.h"
  </code></pre>
  
  <p>The modified <code>*.c</code> files and the <code>newheader.h</code> (which contains three extern arrays) are saved in a directory called <code>try</code> so they have the path: <code>c:\xinu4win\newsrc\try</code></p>
  
  <p>The problem is, when compiling I get this error:</p>
  
  <pre><code> Error: Unable to open include file "newheader.h" 
  </code></pre>
  
  <p>Any ideas why?!</p>
