I tried using -v. However, it didn't tell me what the class path was.

It wasn't the wrong jc1 because I was using absolute path. Neither
"gcj -v" nor "jc1" tells me the class path. How do I explicitly specify
the class path? "--classpath=..." and "--CLASSPATH=..." didn't
seem to help either.

I'm attaching my output below. Hope that's not too annoying.

Thank you!
