## There are various ways to get dependency output from gcc. Here's |

## why we pick this rather obscure method: |

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

## This next piece of magic avoids the `deleted header file' problem. |
| 131 |
## The problem is that when a header file which appears in a .P file |
| 132 |
## is deleted, the dependency causes make to die (because there is |
| 133 |
## typically no way to rebuild the header). We avoid this by adding |
| 134 |
## dummy dependencies for each header file. Too bad gcc doesn't do |
