106     ## why we pick this rather obscure method:

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