Hi,
What do I have to do to get -1 by `(logior -1)' ? Otherwise,
is it just a bug? Setting `binary-as-unsigned' has no effect.
I'm using an old input method sj3-egg[1] but it got not to work.
The following Lisp snippet shows what it does first when opening
the connection to the sj3 server:
(with-temp-buffer
(set-buffer-multibyte nil)
(let ((pt (point-min)))
(insert "\377\377\377\376")
(logior
(lsh (- (logxor (char-after pt) 128) 128) 24)
(lsh (char-after (+ pt 1)) 16)
(lsh (char-after (+ pt 2)) 8)
(lsh (char-after (+ pt 3)) 0))))
It should return -2, but 4611686018427387902 now.
(Oh, it's doubled most-positive-fixnum!)
Thanks.
