| | 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 PERL_CONFIG_SH, |
| | 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. |

| | 39 | ?X: All the symbols that appear twice come only from config.sh (hence the |
| | 40 | ?X: two config.sh in the command line). These symbols will be removed by |
| | 41 | ?X: the uniq -u command. The oldsyms file thus contains all the symbols |
