Oh I guess I got it, we only need to link qga.exe as a standalone binary
unrelated to the qemu-system/user binaries, so we can simplify most of

Hi All,

Currently, we need C++ only for the VSS part of Windows Guest Agent.

Anyway, the VSS source is fully based on Windows API, so in general,
we can rewrite it to C.
