C++ C++；：无法理解编译错误

我起草了这段代码示例，以突出显示相关位。编译代码时：

#include <iostream>

using namespace std;

enum LeaseState {
LEASE_NONE                   = 0x00,
LEASE_READ_CACHING           = 0x01,
LEASE_HANDLE_CACHING         = 0x02,
LEASE_WRITE_CACHING          = 0x04,
LEASE_RH_CACHING             = LEASE_READ_CACHING | LEASE_HANDLE_CACHING,
LEASE_RW_CACHING             = LEASE_READ_CACHING | LEASE_WRITE_CACHING,
LEASE_RWH_CACHING            = LEASE_READ_CACHING | LEASE_WRITE_CACHING |
                               LEASE_HANDLE_CACHING
};

LeaseState
updated_lease_state(LeaseState current, LeaseState new)
{
    return (new | (current ^ new));
}

int main()
{
    cout << "Updated lease state: " << updated_lease_state(LEASE_RW_CACHING, LEASE_READ_CACHING);
    cout << "\n";

    return 0;
}

有人能帮我理解17号线出了什么问题吗

谢谢

新建是一个保留关键字

LeaseState updated_lease_state(LeaseState current, LeaseState newState)
{
     return (newState | (current ^ newState));
}

new是一个保留关键字

LeaseState updated_lease_state(LeaseState current, LeaseState newState)
{
     return (newState | (current ^ newState));
}
