专家你好，
我在编译过程中出现了以下警告信息：
Description Resource Path Location Type
#161-D declaration is incompatible with previous "InitECana" (declared at line 24) DSP2803x_ECan.c /DCDC1500W_Compile line 27 C/C++ Problem

函数在【DSP2803x_GlobalPrototypes.h】中已声明，内容如下：
#if DSP28_ECANA
extern void InitECan(void);
extern void InitECana(void);
extern void InitECanGpio(void);
extern void InitECanaGpio(void);
#endif // endif DSP28_ECANA
DSP28_ECANA在【DSP2803x_Device.h】中定义：
#define TARGET 1
#define DSP28_28035PN TARGET
#if (DSP28_28035PN||DSP28_28034PN||DSP28_28033PN||DSP28_28032PN||DSP28_28031PN||DSP28_28030PN)
........
#define DSP28_ECANA 1
.......
#endif
我将函数声明处的开关注释掉，Warning就被消除了，如下
//#if DSP28_ECANA
extern void InitECan(void);
extern void InitECana(void);
extern void InitECanGpio(void);
extern void InitECanaGpio(void);
//#endif // endif DSP28_ECANA
但是这个【DSP2803x_Device.h】文件是标准库文件，一般不应该修改，而且这里的开关DSP28_ECANA用法也应该没什么问题，为什么会出现这种情况呢？是我的CCS环境配置问题吗？我的编译版本是v6.4.2
