[antlr-interest] Trouble with outdated? c language target?

[funkyworklehead at gmail.com]

I'm getting an error when trying to build a generated lexer and parser
where the target language is C.  I'm trying to use this example
http://www.antlr.org/api/C/buildrec.html , but it seems that the
example is out of date.  I'm getting this error:
file_loader.c:49: error: 'struct ANTLR3_LEXER_struct' has no member
named 'tokSource'

I'm using libantlr3c-3.1b2.tar.gz and antlr-3.1.1.tar.gz.

Does someone have some working skeleton code for the C target language?
