这家伙很懒，什么也没写！

楼上的答案治标不治本

问题的根源出在bsp下面的rtconfig.py

这边配置的platform 是armcc，而GD32E230的keil工程 只能AC6编译

跟踪到`rt-thread\tools\keil.py`的213行中发现 
```python
if 'LOCAL_CCFLAGS' in group:
                MiscControls.text = group['LOCAL_CCFLAGS']
            else:
                MiscControls.text = ' '
```
这里会把C99 参数加上去
这个C99的参数从哪里来  从`drivers\spi`下面的scons脚本里面过来的

打开`drivers\spi\sconscript`
```python
    elif rtconfig.CROSS_TOOL == 'keil':
        if rtconfig.PLATFORM == 'armcc':
            LOCAL_CCFLAGS += ' --c99'
        elif rtconfig.PLATFORM == 'armclang':
            LOCAL_CCFLAGS += ' -std=c99'
```
发现了 因为platform配置的是armcc  导致`--c99`搞进了LOCAL_CCFLAGS里面了
根源便是 `rtconfig.py`的配置
我修改了一份`GD32E230`的`rtconfig.py`配置  有兴趣的可以看看 有心人推送到gayhub做点贡献也是非常欢迎的
