| 111 | 210 ## -MM, not -M (despite what the docs say). Also, it might not be |
| 211 ## supported by the other compilers which use the 'gcc' depmode. | |

| 0 | 230 ## The problem is that when a header file which appears in a .P file |
| 231 ## is deleted, the dependency causes make to die (because there is | |
| 232 ## typically no way to rebuild the header). We avoid this by adding | |
| 233 ## dummy dependencies for each header file. Too bad gcc doesn't do | |
| 234 ## this for us directly. | |
