This was the aftermath of a long series of LLL-related patches. I had not
tested it on alpha yet, and there was a dependency on sizeof(long) remaining
[ in chk_gen_init(); was previously hidden since the precision simply
doubled. I cancelled this possibility since "at this point the precision is
sufficient" ]
