Subject: (uniqstr_print): Now inline.  Return bool, not int.
X-Git-Tag: BISON-1_875~79
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ac72f3e9b5451f0d8ac2f6d8cbdabe250472aeb0;p=platform%2Fupstream%2Fbison.git

(uniqstr_print): Now inline.  Return bool, not int.
(uniqstr_print_processor): New function, to avoid casts.
(uniqstrs_new, hash_initialize, uniqstrs_do):
Use new functions instead of casting old functions unportably.
(hash_compare_uniqstr): Remove unnecessary casts.
