## This next piece of magic avoids the "deleted header file" problem.

## The problem is that when a header file which appears in a .P file
153

## is deleted, the dependency causes make to die (because there is
154
173
## typically no way to rebuild the header). We avoid this by adding
155

## dummy dependencies for each header file. Too bad gcc doesn't do
