* eval.c (block_pass): should not downgrade safe level.

* ext/dbm/extconf.rb: allow specifying dbm-type explicitly.

* ext/dbm/extconf.rb: avoid gdbm if possible, because it leaks
  memory, whereas gdbm.so doesn't.  potential incompatibility.

* io.c (set_outfile): should check if closed before assignment.

* eval.c (rb_eval): should preserve value of ruby_errinfo.

* eval.c (rb_thread_schedule): infinite sleep should not cause
  dead lock.

* array.c (rb_ary_flatten_bang): proper recursive detection.

* eval.c (yield_under): need not to prohibit at safe level 4.

* pack.c (pack_pack): p/P packs nil into NULL.

* pack.c (pack_unpack): p/P unpacks NULL into nil.

* pack.c (pack_pack): size check for P template.

* ruby.c (set_arg0): wrong predicate when new $0 value is bigger
  than original space.

* gc.c (id2ref): should use NUM2ULONG()

* object.c (rb_mod_const_get): check whether name is a class
  variable name.

* object.c (rb_mod_const_set): ditto.

* object.c (rb_mod_const_defined): ditto.

* marshal.c (w_float): precision changed to "%.16g"

* eval.c (rb_call0): wrong retry behavior.

* numeric.c (fix_aref): a bug on long>int architecture.

* eval.c (rb_eval_string_wrap): should restore ruby_wrapper.

* regex.c (re_compile_pattern): char class at either edge of range
  should be invalid.

* eval.c (handle_rescue): use === to compare exception match.

* error.c (syserr_eqq): comparison between SytemCallErrors should
  based on their error numbers.

* eval.c (safe_getter): should use INT2NUM().

* bignum.c (rb_big2long): 2**31 cannot fit in 31 bit long.

* regex.c (calculate_must_string): wrong length calculation.

* eval.c (rb_thread_start_0): fixed memory leak.

* parse.y (none): should clear cmdarg_stack too.

* io.c (rb_fopen): use setvbuf() to avoid recursive malloc() on
  some platforms.

* file.c (rb_stat_dev): device functions should honor stat field
  types (except long long such as dev_t).

* eval.c (rb_mod_nesting): should not push nil for nesting array.

* eval.c (rb_mod_s_constants): should not search array by
  rb_mod_const_at() for nil (happens for singleton class).

* class.c (rb_singleton_class_attached): should modify iv_tbl by
  itself, no longer use rb_iv_set() to avoid freeze check error.

* variable.c (rb_const_get): error message "uninitialized constant
  Foo at Bar::Baz" instead of "uninitialized constantBar::Baz::Foo".

* eval.c (rb_mod_included): new hook called from rb_mod_include().

* io.c (opt_i_set): should strdup() inplace_edit string.

* eval.c (exec_under): need to push cref too.

* eval.c (rb_f_missing): raise NameError for "undefined local
  variable or method".

* error.c (Init_Exception): new exception NoMethodError.
  NameError moved under ScriptError again.

* eval.c (rb_f_missing): use NoMethodError instead of NameError.

* file.c (Init_File): should redifine "new" class method.

* eval.c (PUSH_CREF): sharing cref node was problematic.  maintain
  runtime cref list instead.

  for modules.

* eval.c (rb_set_safe_level): should set safe level in curr_thread
  as well.

* eval.c (safe_setter): ditto.

* object.c (rb_obj_is_instance_of): nil belongs to false, not true.

* time.c (make_time_t): proper (I hope) daylight saving time
  handling for both US and Europe.  I HATE DST!

* eval.c (rb_thread_wait_for): non blocked signal interrupt should
  stop the interval.

* eval.c (proc_eq): class check aded.

* eval.c (proc_eq): typo fixed ("return" was ommitted).

* error.c (Init_Exception): move NameError under StandardError.

* class.c (rb_mod_clone): should copy method bodies too.

* bignum.c (bigdivrem): should trim trailing zero bdigits of
  remainder, even if dd == 0.

* file.c (check3rdbyte): safe string check moved here.

* time.c (make_time_t): remove HAVE_TM_ZONE code since it
  sometimes reports wrong time.

* time.c (make_time_t): remove unnecessary range check for
  platforms where negative time_t is available.

* process.c (proc_waitall): should push Process::Status instead of
  Finuxm status.

* process.c (waitall_each): should add all entries in pid_tbl.
  these changes are inspired by Koji Arai.  Thanks.

* process.c (proc_wait): should not iterate if pid_tbl is 0.

* process.c (proc_waitall): ditto.

* numeric.c (flodivmod): a bug in no fmod case.

* process.c (pst_wifsignaled): should apply WIFSIGNALED for status
  (int), not st (VALUE).

* io.c (Init_IO): value of $/ and $\ are no longer restricted to
  strings.  type checks are done on demand.

* class.c (rb_include_module): module inclusion should be check
  taints.

* ruby.h (STR2CSTR): replace to StringType() and StringTypePtr().

* ruby.h (rb_str2cstr): ditto.

* eval.c (rb_load): should not copy topleve local variables.  It
  cause variable/method ambiguity.  Thanks to L. Peter Deutsch.

* class.c (rb_include_module): freeze check at first.

* eval.c (rb_attr): sprintf() and rb_intern() moved into
  conditional body.
