Wow!

Vladimir, you are the greatest!

I was certain I was going to have to do this, and have been unhappy because
I knew I didn't really have time before Rene's return.

compile.* is a major job, but essential if we want to keep up with Perforce.
For one thing, they've changed the grammar so that it doesn't blow out the
stack on many machines where people have trouble bootstrapping Jam.

I think it's going to be hard to work back from the Perforce version; this
file was one of the greater challenges in doing the conversion to using
string objects. Unless I'm missing something, you'd be better off /adding/
the Perforce features to the existing codebase.
