    Do not set G_GNUC_CONST for get_type() functions
    
    IIRC G_GNUC_CONST means something else: according to its API, we should
    not use it for get_type() functions.
    
    It's an optimization that happens to work, currently at least, and with
    GCC. But there are no guarantees that it will still work in the distant
    future.
    
    And, the less code the better, it's slightly easier to understand.
