+       * inflow.c (terminal_inferior):  Check the results of ioctl's, and
+       print a message if any of them fail.
+       (terminal_ours_1):  Store result of ioctl's for debugging, but
+       don't print (the terminal isn't ours...).
+
        * tm-tahoe.h (FRAME_ARGS_ADDRESS):  No need to offset from frame
        pointer.
