Well, if we compare the size of null programs in C, we can have very
small ones indeed!  But I do not think this is very sensible.  Better
to compare the size of systems that are designed for similar
platforms.

At present we don't have a small configuration for libgcj, so we
cannot make a comparison.  I do believe that we can make a small
configuration of libgcj and do a good job.  But that is all theory
until someone steps up to the plate.
