编译环境：win7 32位 + MinGW-gcc440_1+ Qt 4.8.5 (mingw)
操作步骤：1.先在32位win7系统上解压 MinGW-gcc440_1到D:\Qt\mingw，再安装qt-win-opensource-4.8.5-mingw到D:\Qt\4.8.5
2.下载qt-creator-2.8.1-src，解压到d:\Qt\qt-creator-2.8.1-src文件夹
3. 下載 qt-everywhere-opensource-src-4.8.5,解压到解压到d:\Qt\ qt-everywhere-opensource-src-4.8.5文件夹
将d:\Qt\ qt-everywhere-opensource-src-4.8.5\src\corelib\kernel 目录下qwineventnotifier_p.h 及 qwineventnotifier_p.cpp 复制到 D:\Qt\4.8.5\include\QtCore\private 目录
4.在D:\Qt下创建一个新文件夹build，在开始菜单中找到Qt by Digia 4.8.5(MinGW OpenSource)， 运行其中的Qt 4.8.5 Command Prompt，进入到build文件夹。
5. 输入qmake.exe D:\Qt\qt-creator-2.8.1-src\qt-creator-2.8.1-src\qtcreator.pro -r -spec win32-g++ "CONFIG+=release" "QT_PRIVATE_HEADERS= D:\Qt\ qt-everywhere-opensource-src-4.8.5\include",生成Makefile文件。
然后输入mingw32-make release编译
6.编译出错，错误信息如下：

烦请各位大神指点一二！！！！！！
