I fixed that for 3.0.1 already.

My interpretation is different: as an object of type ObjectReference is
instanciated the compiler has to see the full definition. As
ObjectReference is only defined in a header that includes common.h I think
the compiler is right and the problem would be non-trivial to fix. Stefan

The simples workaround is just to remove those lines and live without aRts
for now.
