C++ 头重新定义 (ws2ipdef.h)

Question

我在我的项目中使用了很多包含(但每个头文件都使用像

#ifndef _HEADER_H 
#define _HEADER_H
...
#endif

现在我从 ws2ipdef.h(自动包含在 windows.h 中)得到这个错误:

c:\program files\microsoft sdks\windows\v7.0\include\ws2ipdef.h(336) : error C2146: syntax error : missing ';' before identifier 'IN6_ADDR_EQUAL'

在 Interface.h(包含在其他一些文件中)我使用:

#define WIN32_LEAN_AND_MEAN

// sockets
#include <winsock2.h>
#include "windows.h"
#include <ws2tcpip.h>

我该如何解决这个问题或任何提示？

谢谢

尝试使用 #pragma once 而不是 ifndef guard，它指定编译器在编译源代码文件时只包含(打开)一次该文件。 http://msdn.microsoft.com/en-us/library/4141z1cx.aspx
