+       * 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.
+       * regex_internal.h (bitset_set, bitset_clear, bitset_contain): Likewise.
+       * regexec.c (check_dst_limits_calc_pos_1, check_subexp_matching_top):
+       Likewise.
+       * regcomp.c (optimize_subexps, lower_subexp):
+       Use CHAR_BIT rather than 8, for clarity.
+       * regexec.c (check_dst_limits_calc_pos_1):
+       (check_subexp_matching_top): Likewise.
+       * 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.
+       * regcomp.c (parse_sub_exp): Do not shift more bits than there are
+       in a word, as the resulting behavior is undefined.
+       * 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.
+       * regex_internal.h (BYTE_BITS): Remove.  All uses changed to
+       the standard name CHAR_BIT.
+       * regexec.c (match_ctx_add_entry): Don't assume that ~0 == -1;
+       this is not true on one's complement and signed-magnitude hosts.
+
+       * regex_internal.h (re_sub_match_top_t): Remove unused member
+       next_last_offset.
+       (struct re_dfa_t): Remove unused member states_alloc.
+       * regcomp.c (init_dfa): Don't initialize unused members.

+       * strstr.c: Include <stddef.h>, for NULL.
+       * strcasestr.c: Likewise.

        * iconvme.h: Add prototype for iconv_alloc.
