|
|
211 ## supported by the other compilers which use the 'gcc' depmode. |

229 ## This next piece of magic avoids the "deleted header file" problem. |
|
5738
|
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 |

14576
