Boost.Move is an infrastructure library needed by Boost itself and
Boost.Atomics has no MACRO_BASED_INTERFACE.
I might sound inconsistent, but it's probably the combination of all three
which trips me off: 'solves no real problem', 'just for the sake of
portability', and 'MACROS'.

Jeff, I fully trust you will make the right decision, and no, you don't make
a big deal out of nothing, IMHO.
