Need some guidance regarding Parsing

Dear All :

I am trying to insert a keyword "zone" . I changed the
"TokenKinds.def" file by adding a line KEYWORD(zone , KEYALL). Now
when I compile a file with this extension I got the
following error:

Look into file ParseDecl.cpp function
Parser::ParseDeclarationSpecifiers. You will need to add a case for
your new keyword there.
