-
-   The GNU C dialect makes bitfields signed by default,

-   regard is bad for portability.
-
-   I chose to make bitfields signed by default because this is consistent
-   with the way ordinary variables are handled: `int' equals `signed int'.
-   If there is a good reason to prefer making bitfields unsigned by default,
-   it cannot have anything to do with the choice of machine.
-   If the reason is good enough, we should change the convention for all machines.
