113## why we pick this rather obscure method:
114## - Don't want to use -MD because we'd like the dependencies to end
115##   up in a subdir.  Having to rename by hand is ugly.
116##   (We might end up doing this anyway to support other compilers.)
117## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
118##   -MM, not -M (despite what the docs say).
119## - Using -M directly means running the compiler twice (even worse
120##   than renaming).

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