Here is the patch which I am testing:
Index: c-decl.c
===================================================================
--- c-decl.c    (revision 1532)
+++ c-decl.c    (working copy)
@@ -1650,11 +1650,7 @@ merge_decls (tree newdecl, tree olddecl,
     TREE_READONLY (olddecl) = 1;

   if (TREE_THIS_VOLATILE (newdecl))

-      TREE_THIS_VOLATILE (olddecl) = 1;
-      if (TREE_CODE (newdecl) == VAR_DECL)

   /* Merge deprecatedness.  */
   if (TREE_DEPRECATED (newdecl))
