I have done it. It is not difficult, but we have to deal with classes
having the same name in different packages. Main, Context and Node are
such classes.

The following shell script is ad-hoc but sufficient to compile SPEC
JVM98. Place the script on the top directory of SPEC JVM98, invoke it
and you have an executable named a.out.
