Qt5 Beta build from Git with qwinoverlappedionotifier error in Windows 7, mingw

[genetica]

Good day

I followed the instructions http://qt-project.org/wiki/Building_Qt_5_from_Git and
downloaded Qt5 Beta from the repository without the QtWebkit and tried to build it
when I got this error somewhere in the build process:

I deduced that the error was in the QtBase tests folder and would not influence the basic functions and tried to compile a simplistic program with qmake and mingw32-make and got the following output:
@d:\temp>mingw32-make
mingw32-make -f Makefile.Debug

mingw32-make[1]: Leaving directory 'd:/temp'@

It compiles an exe file that does nothing. Compiling the .cpp file with mingw32-make directly, a correct working exe file is produced, thus I assume nothing is wrong with my mingw.

Can someone pleas assist me?
