I am writing a parser for MPW's Object Pascal. Some of the extension keywords
to standard Pascal are not reserved. I am using yacc and having some trouble
figuring out a clean way to handle non-reserved keywords.

I know this is a rather vague question, but if anyone has any tips or hints on
handling non-reserved keywords using yacc please let me know.

[There isn't any clean way to handle non-reserved keywords in yacc.  You
have to feed information from the parser back to the lexer to tell it when
a token can be a keyword and when it can't. -John]
