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