title: include stdafx.h in header or source file?
body: <p>I have a header file called stdafx.h and this one is precompiled of course.
  I've read that I should include these files into my .cpp files, but some of these statements are already needed in the header file coming with that.</p>
  
  <p>Should I add the stdafx into my header or into my cpp? I thought it was good practise to put it into the header, but I seem to be obliged to put it into the header instead.</p>
  
  <p>Example:</p>
  
  <p>stdafx contains freeglut.<br>
  my class header file has an attribute of GLenum.</p>
  
  <p>Should I include the stdafx into the .h of the class?</p>
