I am asking you to send the v2 change with updated change log
to show how this change is tested.

Running make isn't sufficient - please verify running the tests
making sure there are no regressions. Since you are changing the
harness, you want to make sure this change You are changing the
harness.

I am asking you to send the v2 change with updated change log
to show how this change is tested.
		fprintf(TH_LOG_STREAM,
-			"# %s: Test ended in some other way [%u]\n",
+			"# %s: Test ended in some other way [%d]\n",
 			t->name,

%d makes sense here in this message.
