Subject: * parse.y (parse_regx): should raise error on untermitated  
 expression interpolation.

* pack.c (pack_unpack): should give length to utf8_to_uv().

* pack.c (utf8_to_uv): add length check.

* massages: replace "wrong #" by "wrong number".

* marshal.c (w_float): output Infinity and NaN explicitly.

* marshal.c (r_object): support new explicit float format.

* eval.c (rb_thread_wait_for): select may cause ERESTART on
  Solaris.

* eval.c (rb_thread_select): ditto.

* array.c (rb_ary_join): dumped core if sep is not T_STRING nor T_NIL.

* array.c (rb_ary_join): buffer size calculattion was wrong.

* array.c (rb_ary_to_s): if rb_output_fs is nil, insert newlines
  between array elements (use rb_default_rs as newline litral)
  [experimental].

* gc.c (init_mark_stack): no need to clear mark_stack.

* gc.c (gc_mark_all): need to handle finalizer mark.

* gc.c (gc_mark_rest): use MEMCPY instead of memcpy.

* gc.c (rb_gc_mark): earlier const check to avoid pusing special
  constants into mark stack.

* numeric.c (fix_to_s): 'to_s' now takes optional argument to
  specify radix. [new]

* bignum.c (rb_big_to_s): ditto. [new]
