## - Don't want to use -MD because we'd like the dependencies to end
|
| 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

| 88 |
|
|
## than renaming).

## is deleted, the dependency causes make to die (because there is
|
| 108 |
|
