WARNING C1106: Non-standard bitfield type

Make的时候出现，然后再Make一次就没有了。Compile也没有，好奇怪。还有Make和Compile的区别？谢谢，我的定义代码如下

typedef union
{
    unsigned char  Byte;

    struct
    {
        unsigned char  bit0         :1;
        unsigned char  bit1         :1;
        unsigned char  bit2         :1;
        unsigned char  bit3         :1;
        unsigned char  bit4         :1;
        unsigned char  bit5         :1;
        unsigned char  bit6         :1;
        unsigned char  bit7         :1;
    } Bits;
} BitField;
