I get:

kelso<2762>gcj bsh/*.java bsh/classpath/*.java --main=bsh.Interpreter -o beanshell
./bsh/classpath/BshClassPath.java: In class `bsh.classpath.BshClassPath':
./bsh/classpath/BshClassPath.java: In method `bsh.classpath.BshClassPath.traverseDirForClassesAux(java.io.File,java.io.File)':
./bsh/classpath/BshClassPath.java:413: Can't find method `listFiles()' in type `java.io.File'.
   		File [] children = dir.listFiles();
                                         ^
1 error

and indeed libjava does not implement the listFiles method, which is
new in jdk 1.2.

I then downloaded KopiSusu-1.9b2.tar.gz.  In settings I changed I
added COMPILER="gcj -C".  I had to modify make.sh because for some
readon gcj -c -classpath would act the way -CLASSPATH is supposed to -
i.e. override the default classpath.  I haven't looked into this.
Instead, I set a CLASSPATH environment variable.  Then the 'util'
directory built fine.  The next directory 'lexgen' failed:

kelso<2758>./make.sh
./src/at/dms/lexgen/TokenDefinition.java: In class `at.dms.lexgen.TokenDefinition':
./src/at/dms/lexgen/TokenDefinition.java: In method `(int,java.lang.String,java.lang.String)':
./src/at/dms/lexgen/TokenDefinition.java:77: Can't assign a value to the final variable `this'.
               this.value = null;
                   ^
1 error

This looks like a failure in the "final variable" testing.  I did comment out
some code there, but my guess is that this didn't use to work, and you
patched your source.  (Hopefully, I'll have time to fix the final
variable testing for gcc 3.0.)
