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).

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
