[antlr-interest] compiling examples with the C target

[Jim Idle]

Did you read the documentation? Assuming you have installed the C runtime correctly, you need

gcc -I. *.c -lantlr3c

The -I. means look in the current directory for include files. It will already look in /usr/include for the installed antlr includes.

Also, remember http://antlr.markmail.org 

You can and should use java -jar and not -cp with 3.2 too.
