| 109 ## up in a subdir. Having to rename by hand is ugly. | |
| 110 ## (We might end up doing this anyway to support other compilers.) | |

| 112 ## -MM, not -M (despite what the docs say). | |

| 131 ## This next piece of magic avoids the `deleted header file' problem. | |
| 132 ## The problem is that when a header file which appears in a .P file | |
| 133 ## is deleted, the dependency causes make to die (because there is | |
| 134 ## typically no way to rebuild the header). We avoid this by adding | |
