If you change

#if defined( __clang__ ) && defined( __has_extension )
# if __has_extension( __c_atomic__ )
#   define BOOST_SP_HAS_CLANG_C11_ATOMICS
# endif
#endif

in sp_counted_base.hpp to

#if defined( __clang__ ) && defined( __has_extension ) && !defined( __c2__ )
# if __has_extension( __c_atomic__ )
#   define BOOST_SP_HAS_CLANG_C11_ATOMICS
# endif
#endif

does it work then?
