[antlr-interest] Compiling ANTLR with gcj/classpath

C target has full Unicode support and can be compiled as c++. Java has java UTF8 support. If you think that getting it to compile with gcj is easier than using the C target, then good luck, but I think you are in the wrong track to be honest.

> The reason for using the Java version and then compiling it (and linking with other object modules), rather than using another target (such as C) is : a) Java has Unicode support, b) the main development (and, presumably, most users) is done in Java, and there will be more feature support, a larger support community, and less bugs there, and c) by linking with other modules developed in other languages, I can provide a native package, rather than require a JVM on a user's machine and using JNI/CNI (reduced support liabilities).

I probably won't be able to contribute much at first (I'm new to ANTLR in general), but I'll probably try to look things over and be a "guinea pig".  In addition to Unicode, my current project requires tree support, which is not yet in the C++ target.
