The hook code in qga/main.c compiles for win32, but it is not used. Did you
intentionally enabled that?

Oh whoops, yes, that is an oversight. I was initially thinking
that CONFIG_FSFREEZE was used in commands-win32.c, since it has
a freeze impl, but I forgot I later learnt it was unconditional.
So we don't need to set these for meson vars for windows.
