This mail arrived with one day delay (obviously caused by the

The patch is not pretty at all, but it works for 2.5.
We should improve this and also some redundant dependencies
like this one later:
$(QEMU_GA_MSI): qemu-ga.exe $(QGA_VSS_PROVIDER)
qemu-ga: qemu-ga$(EXESUF) $(QGA_VSS_PROVIDER) $(QEMU_GA_MSI)
Thanks,
Stefan
