I did a quick diff of the qt logs, and there seems to be three differences:
1) In some places GCC4.4.0 uses -fexceptions -mthreads -frtti
where GCC4.5 uses -fno-exceptions -fno-rtti
(without -mthreads)
2) GCC 4.5 has slightly different warning strings
3) GCC 4.5 terminates earlier with errors

Not sure, I read that to mean that the sdk (or some subset) is
included with mingw-w64, so you don't need the Microsoft one.
