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

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