Any progress on that?

BTW, the current
template<typename T> T func_nand(T v, T op) {
  return ~v & op;
}
is wrong not just by not being atomic (similarly to others), but
furthermore because __sync_fetch_and_nand (and __atomic etc.) are
  return ~(v & op);
instead (GCC < 4.4 did it wrongly as ~v & op; though).
