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

| ## This next piece of magic avoids the `deleted header file' problem. |
| ## The problem is that when a header file which appears in a .P file |
| ## is deleted, the dependency causes make to die (because there is |

| ## dummy dependencies for each header file. Too bad gcc doesn't do |
