* PING *

Attached is just a re-diff.

OK for the trunk?

PS: This patch blocks the patch for finalization of nonallocatable 
intent(out) at http://gcc.gnu.org/ml/fortran/2013-05/msg00135.html (with 
additional test case at 
http://gcc.gnu.org/ml/fortran/2013-05/msg00141.html). It additionally 
blocks me from working on follow-up patches.
