+
+ * internal.h (INTEGER_PACK_NEGATIVE): Defined.
+ (rb_integer_unpack): sign argument removed.
+
+ * bignum.c (rb_integer_unpack): sign argument removed.
+ Non-negative integers generated by default.
+ INTEGER_PACK_NEGATIVE flag is used to generate non-positive integers.
+
+ * pack.c (pack_unpack): Follow the above change.
+
+ * random.c (int_pair_to_real_inclusive): Ditto.
+ (make_seed_value): Ditto.
+ (mt_state): Ditto.
+ (limited_big_rand): Ditto.
+
+ * marshal.c (r_object0): Ditto.
