error: stray ‘\357’ in program

error: stray ‘\274’ in program

error: stray ‘\233’ in program

出现此类错误的原因，在编辑器中使用的utf-8的格式保存源代码中出现了中文的标点符号、

第二种办法：

在Linux虚拟机上开发时，遇到以下错误：

linux@ubuntu:~/software/zion$ 

我的解决办法：

将umount_test.c由utf-8格式另存为ANSI/ASCII格式，重新编译。因为你的编译器默认将文件编码转为UTF-8格式，可winavr作为gcc编译器是不认识这种格式的。
