	function and adapter functions.
	(num_put::_M_group_int): Streamline.
	(num_put::_M_group_float): Streamline.
	(num_put::_M_convert_int): Remove unused parameter names. Choose
	large enough buffer for text.  Use __int_to_char instead of
	__convert_from_v.  Formatted text is now at the end of the buffer.
	(num_put::_M_convert_float): Preliminary fixups.
	* src/locale-inst.cc (__convert_from_v<long long>): Add ifdef.
