   123 ##   (We might end up doing this anyway to support other compilers.)
   124 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
   125 ##   -MM, not -M (despite what the docs say).
   126 ## - Using -M directly means running the compiler twice (even worse
   127 ##   than renaming).
