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.
