Ok.  Thanks for the patch!

I'm just wondering if that "large" new code block for deallocating 
allocatable scalars passed to INTENT(OUT) can't be somehow be simplified 
-- actually, there should already be code to do this for non-scalar 
allocatables; is it possible to merge this somehow?  But I guess it's 
not, because stuff is probably too different there.

Yours,
Daniel
