71 | ## There are various ways to get dependency output from gcc. Here's |
72 | ## why we pick this rather obscure method: |
73 | ## - Don't want to use -MD because we'd like the dependencies to end |
74 | ## up in a subdir. Having to rename by hand is ugly. |
75 | ## (We might end up doing this anyway to support other compilers.) |
76 | ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like |
77 | ## -MM, not -M (despite what the docs say). |
78 | ## - Using -M directly means running the compiler twice (even worse |
79 | ## than renaming). |

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