I don't see how this follows.  Given the new fundamental type "bit" (a
keyword) then it does follow that:

main()
{
	bit	bits[1];
	printf("%d\n", sizeof(bits));
}

must print (at least) "1".  This is OK; sizeof produces the amount of
storage needed to hold an object, not the actual size of the object.
I would expect sizeof applied to an array of 8 bits to also return 1, tho
of course this would be implementation dependent.

Accessing elements of such an array would no doubt generate a little more
code, probably involving the use of a mask, than accessing an element of an
array of char; also, the address of an element of a bit array would likely
be wider than addresses of other objects.  But none of this is against the
rules.
