 129 ##   up in a subdir.  Having to rename by hand is ugly.
 130 ##   (We might end up doing this anyway to support other compilers.)
 131 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
 132 ##   -MM, not -M (despite what the docs say).
 133 ## - Using -M directly means running the compiler twice (even worse
