I'd say they absolutely belong in Boost.Math or Boost.Integer rather than
Boost.MPL. Whether something is a compile-time facility or a run-time facility
should not determine what library it goes in; I'd wager most compile-time
facilities in boost are implemented in terms of MPL. The domain of MPL is
compile-time type sequences and algorithms on those sequences; the domain of
the code in question seems to me to be more strongly related to Boost.Integer's
static_log2 and static_min_max than anything else.
