I have just checked in a hack to Ffile_attributes that casts the uid in 
the stat structure to unsigned short on windows to make it consistent 
with getuid.
You'll need to remove this hack if/when you make the above more 
comprehensive change. I think the current %= 60001 in several places in 
w32.c where uid and gid are initialised will be able to be removed once 
you have made this change too.

I have got at bug report from Thierry Daucourt through

  http://www.emacswiki.org/cgi-bin/wiki/EmacsW32

It looks like this could be a bug in Emacs. The crucial part of that bug 
report are the values investigated at the end of 
`server-ensure-safe-dir' where the user get the following for 
file-attributes and user-id:

 attrs (t 1 -14706 513 (18414 17797) (18414 17797) (18414 17797) 0 
drwxrwxrwx
 nil 34842 (7173 . 33003))
 nth 2 attrs **-14706**
 user id **50830**

He also checked with Cygwin which gave other values than the two 
different above for the uid:

 $ ls -ld server/
 drwxr-xr-x+ 2 my_user mkgroup-l-d 0 Mar 29 14:35 server/
 $ id
 uid=**60830**(my_user) gid=10545(mkgroup-l-d) 
groups=0(root),544(Administrators),545(Users),10545(mkgroup-l-d)


If I do not misunderstand him he has got these values from the unpatched 
version below.

In GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600)
 of 2008-03-25
