| 209 | ##   -MM, not -M (despite what the docs say).  Also, it might not be | 
|---|
| 210 | ##   supported by the other compilers which use the 'gcc' depmode. |

| 212 | ##   than renaming). |

| 228 | ## This next piece of magic avoids the "deleted header file" problem. | 
|---|
| 229 | ## The problem is that when a header file which appears in a .P file | 
|---|
| 230 | ## is deleted, the dependency causes make to die (because there is | 
|---|
| 231 | ## typically no way to rebuild the header).  We avoid this by adding |
