After some googling I see that src/cmd/gc/bisonerrors was
added by Russ in an evening to improve go error messages.
Clinton Jeffery in his "Generating LR syntax error messages
from examples" paper (http://www.cs.nmsu.edu/~jeffery/merr.pdf
-- not sure if this is the same paper as the one in TOPLAS)
says his Merr program works with Berkeley yacc, AT&T yacc &
bison. He also refers to a modified byacc called iyacc.
Might it be worth looking Merr or iyacc? Porting bison to
plan9 seems like a hugh punishment for a quick hack:-)
Implementing Jeffery's directly in yacc might benefit other
parsers as well.
