4b1cb4fe DD |
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. | |
e3046511 | 235 | ## Some versions of gcc put a space before the ':'. On the theory |
