I can build with the following changes (ddk/ntddstor.h replaces winioctl.h): diff --git a/qga/commands-win32.c b/qga/commands-win32.c index 609f3c7..6ebb531 100644 --- a/qga/commands-win32.c +++ b/qga/commands-win32.c @@ -21,8 +21,11 @@ #include #include #include -#include -#include +#include +#include +#include #include #include #include "qga/guest-agent-core.h" But I have to modify ddk/winddk.h (pulled in by ddk/ntddk.h) due to an unfortunately-named 'PCIBus' enum that conflicts with QEMU defs. I don't think there's a reasonable way to work around this so we'll have to stick to the original plan. Since I have a build environment handy I'll go ahead and put together a patch to disable the feature via a configure check/flag. >=20
