I do not see a reason for changing which headers are to be included here.
Actually except for stdio.h all of the other system includes can be removed now.
Thanks!

Neither do I, but the presubmit script complained about <string.h> vs <string>

Agreed, but as I said it should not matter as all you need here is <stdio.h>
which is needed for fprintf and fflush.
