qt-embedded-linux 4.4.3 compiling error

compiling qt-embedded with arm-linux-g++ 4.0 on fedora 9 , the following is the compiling error:
but when i compiling on fedora 4 with the same version arm-linux-g++, there is no error at all.
embedded/qdecoration_qws.cpp: In static member function 'static void QDecoration::startMove(QWidget*)':
../../include/QtGui/../../src/gui/kernel/qwidget.h:139: error: 'QWidgetPrivate* QWidget::d_func()' is private

it seems that fuction d_func is a private slot,
but why works on fedora 4?

this problem is resolved :
i uninstall the fedora 9 and install the debian lenny 5,then any problem is fixed!
