CW编译警告，谁来帮帮我？

beyond850425

问题一：想用#pragma data_seg MY_ZEROPAGE命令自己第一变量的位置，在PRM文件里有分配：
MY_ZEROPAGE                        INTO  Z_RAM;
但还是出现警告：Warning : C4201: pragma data_seg was not handled       timer.c line 13  
我该怎么定义才不出现上面的警告呢？
问题二：想在timer.c源文件里面定义位变量，这些位变量需要在kbi.c文件里面用到，用extern在timer.h里申明，
/*****      *****        Keyboard varriables define in z_ram     ****     *****/
union{
  byte KB_Byte;
  struct
  {
    unsigned my_flag0         :1;          /* 1·ÖÖÓµ½±ê־λt  */
    unsigned my_flag1         :1;          /* 1·ÖÖÓµ½±ê־λt  */
    unsigned my_flag2         :1;          /* 1·ÖÖÓµ½±ê־λt  */
    unsigned my_flag3         :1;          /* 1·ÖÖÓµ½±ê־λt  */
    unsigned my_flag4         :1;          /* 1·ÖÖÓµ½±ê־λt  */
    unsigned my_flag5         :1;          /* 1·ÖÖÓµ½±ê־λt  */
    unsigned my_flag6         :1;          /* 1·ÖÖÓµ½±ê־λt  */
    unsigned my_flag7         :1;          /* 1·ÖÖÓµ½±ê־λt  */
  }Bits;
}Key_Flag;

/*****      *****        Keyboard varriables define in z_ram     ****     *****/

#define Keyboard_Bytes_Operation                 Key_Flag.Bits.KB_Byte                                                                                                                                                                                            #define FLAG_One_Minute                               Key_Flag.Bits.my_flag0                                                                                                   #define FLAG_Ozone_Warnning                       Key_Flag.Bits.my_flag1  //³                      »
#define FLAG_Count_Down_Warnning           Key_Flag.Bits.my_flag2  »
#define FLAG_Low_Warnning                           Key_Flag.Bits.my_flag3/Î
#define FLAG_High_Warnning                          Key_Flag.Bits.my_flag4  »
#define Bit_Counter_Finish_Flag6                   Key_Flag.Bits.my_flag5    
  
/*****      *****        extern在timer.h里申明     ****     *****/     
extern  FLAG_One_Minute;                    
extern  FLAG_Ozone_Warnning;               
extern  FLAG_Count_Down_Warnning;         
extern  FLAG_Low_Warnning;                 
extern  FLAG_High_Warnning;                
 
虽然编译通过，但出现下面的L1813：：：：：：该怎么解决呢？
 
L1823: External object FLAG_Ozone_Warnning in D:\soft development\test_buzzer\test_buzzer_Data\Standard\ObjectCode\kbi.c.o created

#define Keyboard_Bytes_Operation           
这个定义到.h文件中就可以了，你就不需要再外部定义了。
