title: Scope of typedefs
body: <p>I am not at a computer so cannot test this at the moment but have some code to review. I'm still somewhat in a C++ mindframe unfortunatley. </p>
  
  <p>So, when a typedef is declared within a C source file what is its scope? I am aware that to make functions and variables only available within the same translation unit you need to make them static and I was wondering if this is the same for typedefs?</p>
