请各位大神帮帮忙，就在51黑电子论坛下载的代码，是STC电压表的帖子，下载编译时出现这个警告（没改动过任何代码），求指教下小弟是什么问题，要怎样解决。编译里显示：
Build target 'Target 1'

查出是这里的问题：
#if (MAIN_Fosc >= 24000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_30MHZ
#elif (MAIN_Fosc >= 20000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_24MHZ
#elif (MAIN_Fosc >= 12000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_20MHZ
#elif (MAIN_Fosc >= 6000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_12MHZ
#elif (MAIN_Fosc >= 3000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_6MHZ
#elif (MAIN_Fosc >= 2000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_3MHZ
#elif (MAIN_Fosc >= 1000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_2MHZ
#else
#define ISP_WAIT_FREQUENCY ISP_WAIT_1MHZ
#endif
请各大神指教，感谢！！！！！！！！！！！！！！
