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

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