title: C header file dependencies
body: <p>I would always typically include dependencies in my header files so that when adding that header to a source file, I don't need to dig around for the other required headers to make it compile.</p>
  
  <p>However, after reviewing some other coding standards, it appears that this is often banned, with the requirement that a header file will not contain any #include statements.</p>
  
  <p>I can't really find any discussion on this - so what would be the reason for banning such a practice, or is it purely down to preference?</p>
  
  <p>--</p>
  
  <p>E.g.
  typedef.h contains a typedef for U8.
  my_header.h declares void display_message(U8 arg);</p>
  
  <p>Should the reference to typedef.h go into my_source_file.c or into my_header.h ??</p>
