This version is so ancient, I can only wish you good luck. You are on your
own, because nobody here will help you with it

The best way to find out is to look at the list of fixes in later Bison

Since you are insisting on using a very old version, you are essentially on
your own, developing your own version of Bison. Nobody here will care.

I suggested you to change the assignment of the yyerrstatus variable from 3
