| # INCREMENTAL_BUILD: Record the #include file dependencies. |

| # NOTE: We build make include files with the suffix |
| # $(DEPEND_SUFFIX) on every compilation. These are initially |
| # created as temp files just in case a ^C kills it in the middle. |
| # Compiler is smart enough to handle ^C and not create the .o file, or |
| # is supposed to be that smart, but the .$(DEPEND_SUFFIX) file |
| # creation here isn't. |
| # These .$(DEPEND_SUFFIX) files are included by Library.gmk and |
| # Program.gmk, when they exist (Search for 'make dependencies'). |
