- 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.
