|
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. |
