How to prevent QII inferring RAM

On a side note, I am not too sure about the code snippets above to be the proper way of crossing clock domain boundaries for vectors or arrays of vectors, I am thinking about the following is better, how do you think?

   cross_registers: process (rst, clk)
   begin
      if rst = '1' then
         cnt_s                   <= (others => (others => '0'));
      elsif rising_edge(clk) then
         cnt_s                   <= cnt_s(0) & cnt;
         if cnt_s(0) = cnt_s(1) then
            new_cnt            <= cnt_s(1);
         end if;
      end if;
   end process cross_registers;
