This patch below is what I did, *just* to get comp not to complain about
the "missing" .emacs.el.

Then something should be done to make it to compile .emacs, and I'm not
sure where or how.

I can't shake the feeling that I'm thrashing around and someone who knows
the code could do it faster and cleaner.
