Builti-in atomic functions in version 4.7.3

[Rex Dog via gcc-help]

  Hi List Is it safe to use the “Built-in functions for memory modelaware atomic operations” i.e. __atomic_load in version 4.7.3? Unfortunately I am forced to use version 4.7.3 which Iunderstand is not fully C++11 compatibly as show in https://gcc.gnu.org/gcc-4.7/cxx0x_status.html.But it is safe to still use these functions or should they beconsidered experimental? All my code will be run on a x86 with QNX OS. Thanks in advanceAlastair
