Since you're using ANTLR and C++, you are likely using ANTLR2 (perhaps
2.7.7?). In that case I would advise using a Flex lexer or similar rather
than an ANTLR2 lexer in conjunction with your ANTLR2 parsers/treeparsers. 

This is purely from a performance perspective. ANTLR2 lexers have better
support for error handling for instance.
