Last change on this file since 228666c was 228666c, checked in by Martin Decky <martin@…>, 15 years ago

introduce atomic_count_t as the explicit type of the internal value in atomic_t (this is probably better than the chaotic mix of int/long)
atomic_count_t is defined as unsigned, for signed semantics you can cast it to atomic_signed_t
