 Comment from Lennart Poettering:

 5) Atomic.h should be updated to make use of the gcc __sync builtins
    when available. They are nowadays supported on almost all archs and
    support the full set of atomic ops. If you have them then you don't
    need implement those operations manually based on the CAS. I have
    seen that you currently use __sync_bool_compare_and_swap() as a
    fallback. But it should be the first choice nowadays. Both PA and
    glib have been using __sync now for a while and by default. While we
    initially had problems with some of the code generated this has long
    been fixed since then in gcc.
