Bootstrapping is a problem at times especially with a make clean thrown in
at times. Although you can set BOOTSTRAP_JAR before configuring to set a
antlr.jar for use when generating stuff after make clean.

The native gcj build has a very nasty bootstrap problem which I should
still fix. But that's not a high priority since quite a lot of native
executables still crash (without much reason).

Cheers,

Ric
