hi all,

is it ok to commit this patch?

this works around some issues when compiling boost.atomic with clang-3.4:
../../../boost/atomic/detail/gcc-atomic.hpp:961:64: error: no matching
constructor for initialization of 'storage_type' (aka
'boost::atomics::detail::storage128_type')
    explicit base_atomic(value_type const& v) BOOST_NOEXCEPT : v_(0)

thnx, tim
