I think that is where the yacc changes come from, but I must confess I'm only guessing. So far, as Bakul pointed out, only %error-verbose (from memory) stands out in my most recent changes, but there are other reasons and, unfortunately, GNU Bison uses its own extensions to bootstrap, which is where I may well be getting even more muddled up. I will report back in a little while. ++L
