* lib/regcomp.c (re_compile_fastmap_iter, init_dfa, init_word_char): (optimize_subexps, lower_subexp): Don't assume 1<<31 has defined behavior on hosts with 32-bit int, since the signed shift might overflow. Use 1u<<31 instead. * lib/regex_internal.h (bitset_set, bitset_clear, bitset_contain): Likewise. * lib/regexec.c (check_dst_limits_calc_pos_1): (check_subexp_matching_top): Likewise. * lib/regcomp.c (optimize_subexps, lower_subexp): Use CHAR_BIT rather than 8, for clarity. * lib/regexec.c (check_dst_limits_calc_pos_1): (check_subexp_matching_top): Likewise. * lib/regcomp.c (init_dfa): Make table_size unsigned, so that we don't have to worry about portability issues when shifting it left. Remove no-longer-needed test for table_size > 0. * lib/regcomp.c (parse_sub_exp): Do not shift more bits than there are in a word, as the resulting behavior is undefined. * lib/regexec.c (check_dst_limits_calc_pos_1): Likewise; in one case, a <= should have been an <, and in another case the whole test was missing. * lib/regex_internal.h (BYTE_BITS): Remove. All uses changed to the standard name CHAR_BIT. * lib/regexec.c (match_ctx_add_entry): Don't assume that ~0 == -1; this is not true on one's complement and signed-magnitude hosts.
