X-Git-Tag: BISON-1_875~95
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/e46cedb9be2d99b2bf0f6a4ef5f73ba5aafb76ba?ds=sidebyside

(symbol_number_as_item_number,
item_number_as_symbol_number, rule_number_as_item_number,
item_number_as_rule_number): Now inline functions rather
than macros, to avoid casts.
(int_of_rule_number): Remove; no longer used.
