编译包含ace库的程序时，显示系统函数重定义问题

 window环境下编译ACE以及在vs2010上配置ACE

http://blog.csdn.net/luyafei_89430/article/details/8886623

 编写程序时需要注意的：

 #include <iostream>
2 #include "ace\Log_Msg.h"
3 
4 int main(int argv, char *agrv[])
5 {
6     ACE_DEBUG((LM_INFO,"HELLO WORLD"));
7     system("PAUSE");
8     return 0; 

9 } 

 正常使用system函数时，都回包含Windows.h头文件，但是如果用ACE库，就不能再包含，因为ACE库中已经对window的一些系统函数进行的重新定义，如果再次包含则会提示类似如下错误：
