Chris@4: ## The problem is that when a header file which appears in a .P file
Chris@4: ## is deleted, the dependency causes make to die (because there is
Chris@4: ## typically no way to rebuild the header). We avoid this by adding
Chris@4: ## dummy dependencies for each header file. Too bad gcc doesn't do
