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
