Ok, here a question for the trolls:
When I compile kdecore with -DQT_STRICT_ITERATORS I get the following 
undefined symbols:

kuitsemantics.obj : error LNK2001: Nicht aufgel÷stes externes Symbol 
""__declspec(dllimport) public: class QVector<class 
QXmlStreamAttribute>::const_iterator __thiscall QVector<class 
QXmlStreamAttribute>::end(void)const " 
(__imp_?end@?$QVector at VQXmlStreamAttribute@@@@QBE?AVconst_iterator at 1@XZ)".

kuitsemantics.obj : error LNK2001: Nicht aufgel÷stes externes Symbol 
""__declspec(dllimport) public: class QVector<class 
QXmlStreamAttribute>::const_iterator __thiscall QVector<class 
QXmlStreamAttribute>::begin(void)const " 
(__imp_?begin@?$QVector at VQXmlStreamAttribute@@@@QBE?AVconst_iterator at 1@XZ)".

It's because of line 1296 in kuitsemantics.cpp

I'm using 4.4.3 - do I have to compile qt with -DQT_STRICT_ITERATORS too 
or is this a bug? For me it looks like another problem because of the 
exported template class QVector<QXmlStreamAttribute>
