title: Source for parsing C grammar using JavaCC
body: <p><br>
  As an project assignment, I need to parse a plain-C grammar from Java to generate AST output. As a startup, I am using the file c.jj that I have found among grammar files at  </p>
  
  <p><a href="http://java.net/projects/javacc/sources/svn/" rel="nofollow">http://java.net/projects/javacc/sources/svn/</a>   </p>
  
  <p>but I found that it only has syntactic and lexical actions and no real semantics for parsing C source. Is there some other source that incorporate typedef, variables, construct functions, include files?</p>
