	src/corelib/global/qglobal.h
	src/network/socket/qnativesocketengine_winrt.cpp
	src/plugins/platforms/android/androidjniaccessibility.cpp
	src/plugins/platforms/windows/qwindowswindow.cpp

Manually adjusted:
	mkspecs/qnx-armle-v7-qcc/qplatformdefs.h
	to include 9ce697f2d54be6d94381c72af28dda79cbc027d4

Thanks goes to Sergio for the qnx mkspecs adjustments.
