Can someone give me an example how to report line numbers in bison yyerror
function, if
1) bison uses %pure-parser and %locations
2) flex uses %option reentrant bison-bridge bison-locations yylineno


Do I have to include code of my own in the lex/bison file to make it work?
Right now, yyget_lineno() gives always 1 and yylloc->first_line fantasy
numbers (e.g. very large and negative).
