Debuging ANTLR3.4.1-snapshot C target ASTTreeParse.stg

<div>
    Hello,<br><br>
    As part of my ongoing work to build a LaTeXCreole filter for
    PHP/Drupal, I have gone down the route of building AST trees AST
    trees using a tree grammar.<br><br>
    My current grammars antlr-compile in Java but I noticed they did not
    antlr-compile in the C target.<br><br>
    I have traced the problem to 11 characters missing in three places
    in the C target ASTTreeParse.stg string template.<br><br>
    (I was pleasantly surprised at how little time it took me to
    diagnose these two problems.... this is entirely down to the
      cleanness of ANTLR3's architecture.... while there is a lot of
    code, there are a lot of examples with which to intuit your original
    intent... so again, many thanks for the excellent work and thought
    of both Terence and Jim!)<br><br>
    There were two overall problems:<br><br>
    (1)&nbsp;&nbsp;&nbsp; The antlr compiler was complaining that two anonymous
    templates were missing arguments:<br><br><blockquote type="cite">

    I am happy to either raise a gitHub issue (on antlr/antlr3 or
    antlr/antlr4) or issue a pull request.&nbsp; Please let me know how you
    would like me to deal with this.<br><br>
