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).

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
