Errs structures in states

when resolving conflicts due to %nonassoc, bison creates errs structures
attached to states to hold the terminals that must be treated by the
parsing engine as errors. At the same time, it removes the shift transitions
and the lookaheads in reductions that have such conflicts.
However, it seems that such errs structures have no effect: the parse tables
are the same as if the errs structures did non exist.
If that is the case, then they could be removed.
Is this correct?

Thank you
