[ros-dev] Use kernel types in include files?

[Jun Koi]

Please somebody helps me?

I guess I can compile the code in userspace by set a particular macro
(so to deactivate the NTOS_MODE_USER macro), because the kernel code
of ReactOS can do that, too.

Unfortunately I still cannot find how to do that. The code is
complicated compiled in the way I am not familar with, so I am really
struggling here ;-(

Thanks a lot,
Jun
