Packit 6bd9ab

Packit 6bd9ab

## This next piece of magic avoids the "deleted header file" problem.
Packit 6bd9ab
## The problem is that when a header file which appears in a .P file
Packit 6bd9ab
## is deleted, the dependency causes make to die (because there is
Packit 6bd9ab
## typically no way to rebuild the header).  We avoid this by adding
Packit 6bd9ab
## dummy dependencies for each header file.  Too bad gcc doesn't do
Packit 6bd9ab
