Qt does not compiles if disabling Drag and Drop

The compilation fail for windows compact 7 (but probably also for other windows version) if I disable the drag and drop with QT_NO_DRAGANDDROP:

configure -platform win32-msvc2008 -xplatform wince70-2014-armv4i-msvc2008 -debug-and-release -opensource -no-qt3support -no-webkit -no-stl -no-phonon -no-phonon-backend -no-declarative -no-declarative-debug -no-script -no-scripttools -nomake tools -nomake examples -nomake demos -qconfig ssm -no-audio-backend -no-multimedia -nomake docs -nomake translations -confirm-license -no-declarative -no-declarative-debug -no-script -no-scripttools

in my mkspecs I have:

#----------------------------------------

include(../common/wince/qmake.conf)

CE_SDK = xxXXXXxxxxxXXx
CE_ARCH = ARMv4I

DEFINES += QT_NO_NATIVE_GESTURES QT_NOSTANDARDSHELL_UI_MODEL CRT_SECURE_NO_DEPRECATE _WIN32_WCE=0x700 $$CE_ARCH _AMRV7 armv7 ARM QT_NO_CURSOR QT_NO_DRAGANDDROP QT_NO_CLIPBOARD QT_NO_ACCESSIBILITY QT_NO_SESSIONMANAGER

QMAKE_COMPILER_DEFINES += _MSC_VER=1500
#----------------------------------------

The core problem is: QT_NO_DRAGANDDROP QT_NO_CLIPBOARD QT_NO_ACCESSIBILITY QT_NO_SESSIONMANAGER

When I run nmake I see:

qwidget_win.cpp
kernel\qwidget_win.cpp(637) : error C2039: 'oleDropWidgets' : is not a member of QWExtra'
c:\qt\4.8.6-wince70tr7\include\qtgui\private\../../../src/gui/kernel/qwi
dget_p.h(244) : see declaration of 'QWExtra'
kernel\qwidget_win.cpp(637) : error C2039: 'oleDropWidgets' : is not a member of 'QWExtra'

My solution is to put two #ifndef QT_NO_DRAGANDDROP in qwidget_win.cpp into QWidgetPrivate::setParent_sys()

I do not have the big pictures but it seems to me it's just a missing define and the solution works.
Path and code attached.
