谁来解释一下AVRGCC为什么这样编译？算个BUG不？

int main()
{
    unsigned char Temp[5];

    while(1)
    {
        Temp[0]=013;
        Temp[1]=13;
        Temp[2]=015;
        Temp[3]=15;
    }

}

编译结果：

9:                Temp[0]=013;
+00000039:   E08B        LDI     R24,0x0B         Load immediate
+0000003A:   8389        STD     Y+1,R24          Store indirect with displacement
10:               Temp[1]=13;
+0000003B:   E08D        LDI     R24,0x0D         Load immediate

11:               Temp[2]=015;
+0000003D:   E08D        LDI     R24,0x0D         Load immediate

12:               Temp[3]=15;
+0000003F:   E08F        LDI     R24,0x0F         Load immediate
+00000040:   838C        STD     Y+4,R24          Store indirect with displacement
+00000041:   CFF7        RJMP    PC-0x0008        Relative jump

常量的写法，013居然和13不一样？？看不懂了
