Thanks Matthieu.

After some testing, it seems Qt is build in 64bits mode... but when I load
a project file in Visual Studio (e.g. examples/tutorials/adressbook/part1/
part1.vcproj), it complains when linking with QtGui4.lib , saying "module
machine 'x64' conflicts with target machine type 'X86'".

So if I understand correctly, it seems the *.vcproj project files are not
created correctly, or at least they do not contain the needed information
to build/link for 64bits target.

Or am I missing something?
