|  | ##   up in a subdir.  Having to rename by hand is ugly. | 
|  | ##   (We might end up doing this anyway to support other compilers.) | 
|  | ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like | 
|  | ##   -MM, not -M (despite what the docs say). | 
|  | ## - Using -M directly means running the compiler twice (even worse | 
|  | ##   than renaming). |

|  | ## This next piece of magic avoids the `deleted header file' problem. | 
|  | ## The problem is that when a header file which appears in a .P file | 
|  | ## is deleted, the dependency causes make to die (because there is | 
|  | ## typically no way to rebuild the header).  We avoid this by adding | 
|  | ## dummy dependencies for each header file.  Too bad gcc doesn't do |
