## why we pick this rather obscure method:

|

## up in a subdir. Having to rename by hand is ugly.
|
|
## (We might end up doing this anyway to support other compilers.)
|
|
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
|

## -MM, not -M (despite what the docs say).
|
|
## - Using -M directly means running the compiler twice (even worse

|
## than renaming).
