I figured as much. Thanks for looking at it.

FWIW, both seg and cube have "#define YYERROR_VERBOSE", which seems to add the
expected/unexpected text. It might solve the issue to remove the define and
accept slightly less verbose output.

As a side note, while researching this I looked at bison's cvs HEAD. It
appears bison is undergoing some fairly substantial rewriting -- bison.simple
is now in the attic.
