title: Eclipse CDT - "Program "-E" not found in PATH
body: <p>This is driving me NUTS. I recently tweaked around with my C Project's:</p>
  
  <p><strong>C/C++ General ->Paths and Symbols->Includes->GNU C->Include Directories</strong>.</p>
  
  <p>Now, I get the following Error listed:</p>
  
  <pre><code>Program "-E" not found in PATH
  
  Location: Project Properties, C++ Preprocessor \
            Include.../Providers, [CDT Cross GCC Built-in \
             Compiler Settings] options
  </code></pre>
  
  <p>Short of making a new Workspace and starting over, what the heck does this mean, and how do I fix my current project???</p>
  
  <p><strong>Note</strong></p>
  
  <p>Closing Eclipse, Checking out the project from Source-Control Fresh, and restarting still shows the problem!!! How the heck can this be.</p>
