Tested on x86_64-suse-linux, applied on the mainline.
2017-05-15 Pierre-Marie de Rodat <derodat@adacore.com>
* gcc-interface/utils.c (can_materialize_object_renaming_p):
Synchronize with GNAT's Exp_Dbug.Debug_Renaming_Declaration:
process Original_Node instead of expanded names.

* gnat.dg/specs/pack13.ads: New test.
