High uid breaks (message-unique-id)

[Bjorn Solberg <bjorn_ding1@hekneby.org>]

I recently was handed an iMac (G5) to use:

# uname -a
Darwin szbsolberg 8.4.0 Darwin Kernel Version 8.4.0: Tue Jan  3 18:22:10 PST 2006; root:xnu-792.6.56.obj~1/RELEASE_PPC Power Macintosh powerpc
$ id
uid=2108389971(bsolberg) gid=814917730(OFFICE\domain users) groups=814917730(OFFICE\domain users), 81(appserveradm), 79(appserverusr), 80(admin)

and noticed that Gnus wouldn't let me reply to messages.  A little
research lead to this patch:

# diff message.el-7.122 message.el
4770c4770
<      (if (memq system-type '(ms-dos emx vax-vms))
---
>      (if (memq system-type '(ms-dos emx vax-vms darwin))

The reason is that (user-uid) returns 2108389971.0 which is not an
integer which causes trouble in (message-number-base36 ()).  The number
is too high to be truncated to an integer.  I though about dividing by
some number until the value became low enough to be interpreted as an
integer, but decided to skip the whole issue by the above patch.  (This
is running in CVS GNU Emacs.)

It works well for me, but those in the know of the details and
surrounding issues of this may have a better way to deal with it.

Bjorn.
