The added '<include base="ntoskrnl" root="intermediate">include</include>' line in "ntoskrnl.rbuild" was left out, as this include path is already added through the "ntoskrnl.h" precompiled header. (thanks to Hervé for figuring this out)
I applied patches 1904 and 1905 of the Bugzilla bug entry.
See issue #2649 for more details.
