Thanks!  I have two comments:

1.  Should there be conditional code to allow "unsigned long long" and "long
long" base types?
2.  In the notes for "int_least_helper," you could explain why there isn't
specializations for "0" and "5" (guess: to allow errors if the bit count is
above all the built-in types).  Unfortunately, my [1] idea could make your
number system difficult.
