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. | |
