| 19 | ?X: This unit follows the creation of the config.sh file. It adds some | |
| 20 | ?X: special symbols: defines from patchlevel.h file if any and CONFIG, | |
| 21 | ?X: which is set to true. Then, we try to keep all the new symbols that | |
| 22 | ?X: may come from a hint file or a previous config.sh file. | |

| 38 | ?X: All the symbols that appear twice come only from config.sh (hence the | |

| 40 | ?X: the uniq -u command. The oldsyms file thus contains all the symbols | |
