| 918 | This option preserves the old syscall interface along with the |

| 1264 | Say Y here to include the kernel code necessary if you want to run |
| 1265 | Acorn RISC OS/Arthur binaries under Linux. This code is still very |
| 1266 | experimental; if this sounds frightening, say N and sleep in peace. |
| 1267 | You can also say M here to compile this support as a module (which |
| 1268 | will be called arthur). |
