自己裸机移植RTThread到STM32F407开发板上，想用C/C++混合编程，出现了以下问题
  1.在C/C++下不添加“--cpp11“时显示
```c
`  Build target 'Target 1'
  compiling main.c...
..\rt-thread\T.h(14): error:  #20: identifier "class" is undefined
   class CTIM 
..\rt-thread\T.h(15): error:  #65: expected a ";"
  {
..\rt-thread\T.h(28): warning:  #12-D: parsing restarts here after previous syntax error
  };
..\rt-thread\T.h(39): warning:  #1-D: last line of file ends without a newline
  #endif
User\main.c: 2 warnings, 2 errors
compiling T.cpp...
T.h(39): warning:  #1-D: last line of file ends without a newline
  #endif
T.cpp: 1 warning, 0 errors
".\Obj\Template.axf" - 2 Error(s), 3 Warning(s).
Target not created.`
```
2.添加”--cpp11“之后显示
  }
```c
board.c: 1 warning, 0 errors
linking...

查过百度和官方论坛，没找到问题的解决方法，想问问各位怎么解决
