| 76 | Your yacc program may need extra flags to normally process the parser sources. | |
| 77 | Do NOT specify any -d or -v flags here, since those are explicitly known | |
| 78 | by the various Makefiles. However, if your machine has strange/undocumented | |
| 79 | options (like -Sr# on SCO to specify the maximum number of grammar rules), then | |
| 80 | please add them here. To use no flags, specify the word "none". | |
