c++/71675 - __atomic_compare_exchange_n returns wrong type for typed enum__atomic_compare_exchange_n is documented to return bool but when its operands are of one of the character types or derived from it (such as a class enum in C++) it converts the bool result to that type. The attached patch corrects that to prevent this conversion, analogously to what's already being done for __sync_bool_compare_and_swap.
