I guess when I first forwarded this to the list, the header
was not included. What follows is the entire posting from
the ba.jobs.contract Usenet group which includes the name of
the person who posted it. dberg@netcom.com is the person to
answer all questions about the job.

The only sane way to count the number of 1 bits in a byte is to use
a lookup table:
return table[result];
On an intel chip this produces ONE opcode:
