| 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. | |

| 229 ## This next piece of magic avoids the "deleted header file" problem. | |
| 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. | |
| 235 ## Some versions of gcc put a space before the ':'. On the theory | |
| 236 ## that the space means something, we add a space to the output as | |
| 237 ## well. hp depmode also adds that space, but also prefixes the VPATH | |
| 238 ## to the object. Take care to not repeat it in the output. | |
