113 |
|
|
## why we pick this rather obscure method: |
114 |

|
## - Don't want to use -MD because we'd like the dependencies to end |
115 |
|
|
## up in a subdir. Having to rename by hand is ugly. |
116 |
|
|
## (We might end up doing this anyway to support other compilers.) |
117 |
|
|
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like |
118 |
|
|
## -MM, not -M (despite what the docs say). |
119 |
|
|
## - Using -M directly means running the compiler twice (even worse |
120 |
|
|
## than renaming). |

## This next piece of magic avoids the `deleted header file' problem. |
138 |
|
|
## The problem is that when a header file which appears in a .P file |
139 |
|
|
## is deleted, the dependency causes make to die (because there is |
140 |
|
|
## typically no way to rebuild the header). We avoid this by adding |

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

## this for us directly. |
