Unable to build Qt 4.4.0 debug libs with MinGW (pch error)

Hi,

I'm having problems to build Qt 4.4.0 Debug Libraries with MinGW g++ compiler version 3.4.5 (stable). When selecting "Qt 4.4.0 (Build Debug Libraries)" from start menu, compiling stops in process of compiling QtWebkit debug library:

Code:

, version of g++ compiler is:

Is this a known bug, or is compiler version too old for Qt 4.4.0?

Thanks for any hints,

Try to comment out the following line in D:/Programme/Qt/4.4.0-MinGW/src/3rdparty/webkit/WebCore/WebCore.pro:
Code:

#PRECOMPILED_HEADER = $$PWD/../WebKit/qt/WebKit_pch.h
