Bug#394021: FTBFS on ia64: libjack.so: undefined reference to `__sync_fetch_and_add_si'
jack-audio-connection-kit fails to build with gcc 4.1 and 4.2 with an
undefined reference to `__sync_fetch_and_add_si' error. This doesn't
happen when you use gcc 4.0. Since I have no idea whether this is a
bug in your package or in GCC, I'm CCing the debian-ia64 list.
