Released versions of boost do not include it yet, but it is defined in trunk:

Obviously not in the pending release ;-) so I have slowed down a bit. I would
however propose this for fast-path review for maybe the next release -- after
all it merely formalizes an interface for atomic operations currently
dispersed throughout the library. The real chore will however probably be
replacing all other instances of atomic variable implementations.
