You can workaround that by changing the include order, or you could
redefine Status while including the windows headers.  Or you could
try to convert the above to a typedef.

Other than that, in theory the windows headers should not use variable
like this without underscoring them, as in

  typedef void __RPC_API RPC_OBJECT_INQ_FN(UUID *__ObjectUuid,UUID *__TypeUuid,RPC_STATUS *__Status);

to avoid such clashes, but that requires some heavy patching of the
upstream header files.  While desirable, nothing for short-term...
