[antlr-interest] C target: problems with setCharStream

[Jim Idle]

I'll take a look at it, but perhaps that example is wrong? Please try
with the official examples for the C target if you would - I suspect
that the use of the C objects is not correct in that example..

I am aware of those warnings but have not had time to deal with them
this week. A bug fixing session will happen this weekend.
