/* PR c/68966 - atomic_fetch_* on atomic_bool not diagnosed
Test to verify that calls to __sync_fetch_op funcions with a _Bool
argument are rejected. This is necessary because GCC expects that
all initialized _Bool objects have a specific representation and
allowing atomic operations to change it would break the invariant. */
