Yes.  Note that this isn't fully implemented in libgcj.  Parts are
missing.

Right now, yes.  I think this could be changed if we had another GC
available.

The null GC isn't really that useful.

You're right, the GC is chosen at configure time and is built in to
libgcj.  There is no way to change it dynamically.
