Intuitively this seems to make sense. My issue is that I don't have
hundreds of .lpp files, and only anticipate one for the entire source
tree. Further, there's a little ad hoc magic I've got to do on the only
one in running its generated .cpp through sed to insert some code. If
you have an elegant suggestion for this, I'm all ears.

Excellent idea for extending the silent rules. I was actually going to
ask you guys that next. Now I just wish colorgcc recognized it ;)
