Subject: (lbitset_set, lbitset_reset): Do not assume that
X-Git-Tag: BISON-1_49b~35
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/c340180d81bf64712d3db24f157cd8030a08633a

(lbitset_set, lbitset_reset): Do not assume that
bitset_word is the same width as int.
(lbitset_op1): Use -1, not ~0, as memset arg (for
portability to one's complement hosts!).
