title: c++ fails to find includes
body: <p>Just installed build-essentinals in debian 7. 
  But i noticed the includes for c++ are in /usr/include/c++/4.7... 
  Does anyone why? Includes used to be in /usr/include, as far as I remember...</p>
  
  <p>Everything fails now... 
  i.e. </p>
  
  <pre><code>main.c:2:20: fatal error  iostream: No such file or directory
  </code></pre>
  
  <p>And even if i include it with -I, headers are called from headers and it won't find anything, like:</p>
  
  <pre><code>/usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory
  </code></pre>
  
  <p>So beacuse bits is NOT in /usr/include but in /usr/include/c++/4.7 compiler can't find it...</p>
  
  <p>I'm using g++</p>
  
  <pre><code>crafter# g++ -o craft main.cpp 
  In file included from /usr/include/c++/4.7/x86_64-linux-gnu/bits/os_defines.h:40:0,
                   from /usr/include/c++/4.7/x86_64-linux-gnu/bits/c++config.h:414,
                   from /usr/include/c++/4.7/iostream:39,
                   from main.cpp:2:
  /usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory
  </code></pre>
  
  <p>compilation terminated.</p>
  
  <p>Anyone knows how to fix this?</p>
  
  <p>Thanks for your help!</p>
