C++ `#包括<；iostream>；`用“-std=c++；0x`坏了

如果我将

-std=c++0x

指定给g++，那么我就不能

#include

。我收到以下错误消息（mingw下的g++4.4.0）：

你知道为什么吗？这在最新的g++中已经修复了吗？（如果是这样的话，有人知道如何将最新的g++集成到Qt中吗？

这似乎是一个问题。有一个简单的补丁（在最后）In file included from c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/bits/postypes.h:42, from c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/iosfwd:42, from c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/ios:39, from c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/ostream:40, from c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/iostream:40, from f.cpp:1: c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/cwchar:159: error: '::swprintf' has not been declared c:\qt\2010.05\mingw\bin\../lib/gcc/mingw32/4.4.0/include/c++/cwchar:166: error: '::vswprintf' has not been declared
