| 29 | The following header is included in order to provide one instance of the symbol vcos_deprecated_code. |
| 30 | Any other inclusions of this header (or "vcos_deprecated_code.inc" for assembly language) will cause the linker to warn |

| 32 | The idea is to include this header file for the source files which are deprecated. |
| 33 | Therefore the above warnning in a build indicates that the build is using deprecated code! |
