[boost] [type_traits][units] migrating from ice_and

Hi!

I've noticed that boost/type_traits/detail/ice_or.hpp and 
boost/type_traits/detail/ice_and.hpp have been deprecated. Both headers are 
used as an implementation detail in boost/units/scaled_base_unit.hpp, now 
resulting in lots of warnings:

In file included from .../boost/units/scaled_base_unit.hpp:20:
.../boost/type_traits/detail/ice_or.hpp:17:10: warning: NOTE: Use of this 
header (ice_or.hpp) is deprecated [-W#pragma-messages]
# pragma message("NOTE: Use of this header (ice_or.hpp) is deprecated")

Question: Is there a known migration path from type_traits to what? MPL?
Or am I better off copying both files to Boost.Units and be done?

Yours,

Jürgen
