QT 5.0.1 with mingw32 installation broken.

[mk_olc]

Hi,

I installed the following package:
http://releases.qt-project.org/qt5/5.0.1/qt-windows-opensource-5.0.1-mingw47_32-x86-offline.exe

but building of projects is not working. I tried to build the analogclock from examples section, but:

Where should I start to search for the bug? Is mingw-32 the core of the problem?
Thanks in advance!
