I just came across a nasty problem with all this.

If you build a copy of gcj from CVS it won't pick up the system-wide
database, because that is in /usr/lib/gcj-4.1.0/, not wherever gcj has
been installed.  We need a way to rebuild the database into the right
place for the installed gcj.

Having gcj-dbtool --rebuild in gcj itself will solve this very nicely
because it will rebuild the installed copy, wherever that happens to
be.
