c-free 编译问题，
用的是c-free5，电脑系统windows8，64位，运行最基本的：#include<stdio.h>
#include<stdlib.h>
int main()
{
printf("成功案例，嘻嘻\n");
system("pause");
return 0;
}
在debug的情况下出现：
--------------------配置: mingw5 - CUI Debug, 编译器类型: MinGW--------------------
检查文件依赖性...
正在编译 C:\Users\小辉辉\Desktop\uiop\uiop.c...
[Warning] cc1.exe: warning: command line option "-Wold-style-cast" is valid for C++\ObjC++ but not for C

[Warning] cc1.exe: warning: command line option "-fno-for-scope" is valid for C++\ObjC++ but not for C
构建中止 uiop: 1 个错误, 3 个警告
在release的情况下：
--------------------配置: mingw5 - CUI Release, 编译器类型: MinGW--------------------

正常，不知道哪里错了怎么会这样啊，系统问题还是编译器问题啊
