of basic_string pre-2003-06-13; remove fully-dynamic-string stuff.
* include/ext/rc_string_base.h (_M_refcopy): Move inside the
_Rep class and remove code in macro.
(__rc_string_base()): Construct with _S_empty_rep()._M_refcopy().
(_M_dispose, _M_leak_hard): Remove code in macro.
(_S_construct): Return _S_empty_rep()._M_refcopy() for empty string.
(_M_grab): Adjust.
* include/ext/rc_string_base.h (_Rep::_M_refdata()): Minor tweak,
mark throw().
