| 137 | ## up in a subdir. Having to rename by hand is ugly. | |
| 138 | ## (We might end up doing this anyway to support other compilers.) | |
| 139 | ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like | |
| 140 | ## -MM, not -M (despite what the docs say). | |

| 161 | ## is deleted, the dependency causes make to die (because there is | |
| 162 | ## typically no way to rebuild the header). We avoid this by adding | |
