But how does it tell that it's time to emit the <directory> directive?

Oh, I think I see what you mean.  Since we currently don't handle at
all the case of `gcc -E -x cpp-output' to emit an unmodified copy of
the input file, it's just a matter of the preprocessor output emitting
<directory>getpwd() after the initial line directive, and handling
this directive entirely in cc1.  Does this sound acceptable to you?
If so, I'll give it a try tonight.
