Are you aware of the blockers that prevent Boost.Atomic from being
merged to release? Perhaps there are minor problems and we could help
the author to resolve them and merge Boost.Atomic ourselves.

Relying on an unreleased version of gcc looks nearly unacceptable to
me. I know previous versions did not support atomic structs but this
is hardly the reason to ignore atomic integers that were supported
since gcc 4.4. Can Boost.Lockfree be adopted to use integer atomics?
