I believe these are water drain holes. They were added so that the condensation or water getting into the insides of the frame would drain out and not cause rusting or freezing inside the frames.

Just checked TM 9-772 and yes it must be for the defroster cable. See figure 18 on page 30 in the 1945 edition and figures 17-19 on pages 22-24 in the 1944 edition.
