See again http://www.lysator.liu.se/c/duffs-device.html commenting from
Tom himself.  His initial posting was about the loop
	send(short *to, short *from, int count)
        { do *to = *from++; while(--count>0); }

That's basically a memcpy().  I'm not old enough to know if Tom really is
the inventor of this "use" of C features, but not even Tom remembers ;-)


Ciao,
Michael.
