matlab 28m35,使用F28M35添加自己写的头文件时，出现了“XXX”has already been declared in the current scope的问题...
struct TODAY_BIT {
Uint16 MORNING:16;
Uint16 AFTERNOON:16;
};
union TODAY_REG{
Uint32 all;
struct TODAY_BIT bit;
};
我在頭文件里寫了上述兩組結構，然后出現了如下的報錯：
Description Resource Path Location Type
"TODAY_BIT" has already been declared in the current scope ECAN_T&R.h /BasedOnCan_M3_2_Eyior line 44 C/C++ Problem
Description Resource Path Location Type
"TODAY_BIT" has already been declared in the current scope ECAN_T&R.h /BasedOnCan_M3_2_Eyior line 44 C/C++ Problem

分割線
***************************************************************************************************************************************************
因為頭文件里面的內容是自己寫的，所以不存在重復定義的問題。至于為什么提示重復聲明，我真的不知道。
求大神解答，這個問題困惑我很久了。
附頭文件全部代碼：
