[Qemu-devel] [PULL 21/35] qga: drop < Vista compatibility

[Paolo Bonzini]

From: Marc-André Lureau <address@hidden>

Building QGA for XP seems possible so far: the dependency on
libqemuutil.a implies building qemu-thread-win32.c, which requires
Vista API since commit 12f8def0 (v2.9). But qemu-thread isn't being
used in QGA, the resulting binary may still work on XP.  XP is no
longer supported for the past 4.5y, it's time to drop support for it.
