[antlr-interest] How to make case insensitive token checker for the lexical analysis part of antlr in C program?

[金杰]

I find it in the wiki, thank you all..
http://www.antlr.org/wiki/pages/viewpage.action?pageId=1782

I still have a question to ask: any C project that using antlr3?

I find many Java project that using antlr, e.g. Hive, Esper (a stream
process engine)
Thanks to these open sourced Java project, I learned a lot skills about
using antlr3 in java.

we have the wiki (
http://www.antlr.org/wiki/display/ANTLR3/Using+the+ANTLR3+C+Target)
but, I want to look for a more complex one.
So, could you figure out any C project that using antlr3?

Thanks.
