I've tried to do this now, see attached patch. somehow this triggers use-
building for declarations, i.e.:

int i = 0;

-> i will have 1 use... this is different from the current behavior and hence 
probably a nasty regression. somehow I can't figure out where it is introduce, 
could someone else try to play a bit with the patch and see what the reason 

much appreciated
