Acknowledged. But I thought it was only a warning...
(The make_single_applets.sh didn't show compiler's or make's stderr to the
screen, and so I didn't notice. By the way, would make_single_applets.sh try to
do this trick? https://stackoverflow.com/questions/2871233/)

And great job on making another optimization with depmod and lsmod two-applet
configuration.
