129 ## up in a subdir. Having to rename by hand is ugly. | |
130 ## (We might end up doing this anyway to support other compilers.) | |
131 ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like | |
132 ## -MM, not -M (despite what the docs say). | |
133 ## - Using -M directly means running the compiler twice (even worse | |
134 ## than renaming). | |

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