This is a known issue with static linking (asking google will give you 
good results). In newer GCJ revisions, you only need the MessageBundles 
if you have errors in your regular expression.
So, you can either update to a newer GCJ or add the message bundles 
explicitly to the compilation (they are in libgcj.a, you can extract 
them using "ar").
