Will this extension allow us to have (almost) 64-bit Emacs Lisp integers
on 32-bit system? In that case, I think it's a rather momentous
extension -- there's a lot of numerical data that Gnus has to deal with
(for instance, IMAP sequence numbers) that will overflow, er, 28 bit
data (or whatever the limit is on 32-bit hosts these days), and requires
somewhat awkward work-arounds.
So if I understand this correctly (and I might not do -- it's Friday),
it seems like a really great development.
