Well, no it wasn't.  The original problem was to convert 0x12345678
into something like

	bit_set[0] = 3;
	bit_set[1] = 4;
	bit_set[2] = 5;
	bit_set[3] = 6;
	bit_set[4] = 9;
	...
	bit_set[15] = -1;   /* Excuse me if my counting is off. */

for which I suspect Mr. Bernstein's proposed solution sketch is
probably pretty good.
