71 ## There are various ways to get dependency output from gcc. Here's
72 ## why we pick this rather obscure method:
73 ## - Don't want to use -MD because we'd like the dependencies to end
74 ## up in a subdir. Having to rename by hand is ugly.
75 ## (We might end up doing this anyway to support other compilers.)
76 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
77 ## -MM, not -M (despite what the docs say).
78 ## - Using -M directly means running the compiler twice (even worse
79 ## than renaming).

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