137##   up in a subdir.  Having to rename by hand is ugly.
138##   (We might end up doing this anyway to support other compilers.)
139## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
140##   -MM, not -M (despite what the docs say).
141## - Using -M directly means running the compiler twice (even worse
142##   than renaming).

161## is deleted, the dependency causes make to die (because there is
162## typically no way to rebuild the header).  We avoid this by adding
163## dummy dependencies for each header file.  Too bad gcc doesn't do
