 529 # BISON-STDERR.
 530 #
 531 # If TEST-SPEC contains the attribute `last-state', check that the value
 532 # of TABLES-OR-LAST-STATE is the index of the last state generated for
 533 # the grammar; in other words, check the number of states (minus one).
 534 # Otherwise, check that everything in the `.output' file starting with
 535 # the definition of state 0 is the same as the entire value of
