105 | ## There are various ways to get dependency output from gcc. Here's | |
106 | ## why we pick this rather obscure method: | |
107 | ## - 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). | |

130 | ## 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 | |
