    43 // Before <stdatomic.h> was available, there was only one atomic type
    44 // equivalent to atomic_size_t. This means that in some places, atomic_t can
    45 // be replaced with a more appropriate type (e.g. atomic_bool for flags or
    46 // a signed type for potentially signed values).
    47 // So atomic_t should be replaced with the most appropriate type on a case by
    48 // case basis, and after there are no more uses, remove this type.
