Please consult the examples and API documentation and turn up the
warning levels on your compiler. The input to the token stream is not
the lexer, but the lexer token set.

tokens = antlr3CommonTokenStreamSourceNew (ANTLR3_SIZE_HINT,
TOKENSOURCE(lexer));

(Note that TOKENSOURCE is for Antlr 3.1 and above, which you should
probably use now.

I am really surprised that your C compiler didn't give you a warning
about this - what compiler is it?
