Comment (by pdimov):

 Most versions of clang appear to provide a working {{{<atomic>}}}, so
 we'll probably use that instead of the obsolete {{{!__sync}}} intrinsics.

 https://github.com/boostorg/smart_ptr/commit/fed15ad8c50921cbfc0365156e4e4f4454dc1b91

 allows you to turn {{{std::atomic}}} support on manually by {{{#define
 BOOST_SP_USE_STD_ATOMIC}}}. This will eventually become the default when
 {{{std::atomic}}} is autodetected to be present.
