54: ## - Don't want to use -MD because we'd like the dependencies to end
55: ## up in a subdir. Having to rename by hand is ugly.
56: ## (We might end up doing this anyway to support other compilers.)
57: ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
58: ## -MM, not -M (despite what the docs say).
59: ## - Using -M directly means running the compiler twice (even worse
60: ## than renaming).

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