Problem compiling QTBus binding on win32

Hi all,

currently I'm trying to compile the Qt DBus binding on windows using gcc 
3.4.5 and QT 4.1.2 (the last official qt release) and have problems with 
some Q_FOREACH statements:

the related part in qdbustypehelper_p.h ist listed below:

static inline List fromVariantList(const QVariantList &list)
    {
        List tmp;
        Q_FOREACH (const QVariant &v, list)
            tmp.append(fromVariant(v));
        return tmp;
    }

A similar problem occurs in qdbusintegrator.cpp with the typ QObjectList:

qdbusintegrator.cpp:1100
            const QObjectList &children = obj->children();

            // find a child with the proper name
            QObject *next = 0;
            foreach (QObject *child, children)
                if (child->objectName() == path.at(i)) {
                    next = child;
                    break;
                }


Any idea what's going wrong or is the qt bus binding not compilable with 
qt 4.1.2  ?

Ralf
