if you want to build Qt for 64 bit then all you need to do is ensure you
build it using the 64bit command prompt which comes from  Visual Studio.
It will be build in a 64bit environment. There is no change in mkspec for 64
the existing mkspec for both 32 will still work for 64 which is
win32-msvc2008 .
