## why we pick this rather obscure method: |

## - 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. |
149 |

|
## (We might end up doing this anyway to support other compilers.) |
150 |
|

## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like |
151 |
|
|
## -MM, not -M (despite what the docs say). |
152 |

## than renaming). |

## This next piece of magic avoids the "deleted header file" problem. |
171 |
michael |
912 |
## The problem is that when a header file which appears in a .P file |
172 |
|
|
## is deleted, the dependency causes make to die (because there is |
173 |
|
|
## typically no way to rebuild the header). We avoid this by adding |
174 |

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

## this for us directly. |
