Cool, thank you Adam, I'll try it and report back where I got with
executable size reduction. In the meantime, can someone more 
knowledgeable tell the poor java programmer if it's possible to link
a different version of the runtime library (a stripped one, for example)
instead of the standard libgjc? I've tried to read the gcj online 
manual, but didn't have much luck...
