关于msp430结构体定义的问题

我在.h头文件中声明如下

typedef struct          {signed int X;

                                 signed int Y;          

                                   signed int Z;} S_INT16_XYZ;

extern S_INT16_XYZ MPU6050_ACC_LAST,MPU6050_GYRO_LAST;

extern S_INT16_XYZ GYRO_OFFSET,ACC_OFFSET; 

C程序中这样定义的

S_INT16_XYZ GYRO_OFFSET,ACC_OFFSET;

S_INT16_XYZ MPU6050_ACC_LAST,MPU6050_GYRO_LAST;

但是用IAR编译时，不通过

错误提示是

Error[Pe040]: expected an identifier

Error[Pe757]: variable "S_INT16_XYZ" is not a type name

另外，楼主发错地方了，给楼主转回430版块去了
