[求助]processor expert标志位共用问题 expert, processor, 求助

各位大侠：

    小弟用processor expert，定义的标志位（如：FG_LF_Moved）如何在两个文件中（如：main和event）共用？敬请大侠指教。 

typedef union
{
   unsigned char FlagByte;   
   struct {
   unsigned char Flag0    :1;          
   unsigned char Flag1    :1;         
   unsigned char Flag2    :1;         
   unsigned char Flag3    :1;        
   unsigned char Flag4    :1;         
   unsigned char Flag5    :1;         
   unsigned char Flag6    :1;      
   unsigned char Flag7    :1;          
          } Bits;
} Flag;

Flag GsFlag1;

#define FG_LF_Moved           GsFlag1.Bits.Flag0

用include会出现错误，提示包含冲突。用extern该怎么说明这种共用体类型呢？
