this thing hit send all by itself.  as I was saying, before, I was
able to compile programs just fine.  now I can't.  I haven't changed
anything.
I don't know - maybe the mcafee antivirus or webroot spysweeper got a
hold of something and deleted it, but that seems farfetched.

I am using iterators in this program.
