| | | ## (We might end up doing this anyway to support other compilers.) |
|---|

|---|
| | | ## -MM, not -M (despite what the docs say). Also, it might not be |
|---|
| | | ## supported by the other compilers which use the 'gcc' depmode. |

| | | ## 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 |
|---|
| | | ## this for us directly. |
|---|
| | | ## Some versions of gcc put a space before the ':'. On the theory |
|---|
| | | ## that the space means something, we add a space to the output as |
|---|
| | | ## well. hp depmode also adds that space, but also prefixes the VPATH |
|---|
| | | ## to the object. Take care to not repeat it in the output. |
