True, this is not what I originally reported.  My original problem was fixed
by including the exception's .java in the list of prerequisites and
specifying the -c option.  But now I have three .o files and can't figure
out how to combine them into one executable.

When I execute:
gcj -o test Test.o /u/jddahl/java/objects_solaris/test/core/LotNumber.o
/u/jddahl/java/objects_solaris/test/core/InitializationException.o

I get the following error:

It's almost as if I need to include the #ifndef preprocessor directive.
