    hurd: Make error_t an int in C++
    
    Making error_t defined to enum __error_t_codes conveniently makes the
    debugger print symbolic values, but in C++ int is not interoperable with
    enum __error_t_codes, leading to C++ application build issues, so let's
    revert error_t to int in C++.
