| 22 | # Its purpose is to provide support for: |
|---|
| 23 | # |
|---|
| 24 | # 1) recursion where necessary, and only then (building .o's), and |
|---|
| 25 | # 2) building and debugging cc1 from the language subdirectory, and |
|---|
| 26 | # 3) nothing else. |

| 29 | # language makefile fragment, of course. |
