In all fairness, the line number accounting is also important for warnings and errors.
Your list would probably also be more useful if you dropped most of the compilation related functions: At least yylex, scan_const, and yyparse. Probably, worrying about regexp compilation isn't that useful either, so those functions could go, too. What are the runners up?
