It's hard to believe that the bug has always been there on foreign machines...
A few other things:

1) I had the feeling that we have already discussed this in the past.
Take a look at
http://www.cygwin.com/ml/cygwin-patches/2002-q4/msg00255.html
(last line). Thanks to google :)

2) About http://cygwin.com/ml/cygwin/2010-01/msg00334.html
USERS is already always added to the token. It's done in get_token_group_sidlist.
This raises the possibility that fixing the language problem won't fix the current bugs
were user32 can't be loaded, and also with ws2_32.dll in your message

3) There is another major bug: scripts don't get executed while impersonated.
The problem is in access.

cron has setuid and tries to run sendmail ==> /bin/cronlog
  502 3438682 [main] cron 4000 av::fixup: C:\Program Files\cygwin_1.7\bin\cronlog is possibly a 
script
 1832 3440514 [main] cron 4000 seterrno_from_win_error: 
../../../../src/winsup/cygwin/security.cc:766 windows erro$
   61 3440575 [main] cron 4000 geterrno_from_win_error: windows error 6 == errno 9
   21 3440596 [main] cron 4000 __set_errno: void seterrno_from_win_error(const char*, int, 
DWORD):319 val 9
   21 3440617 [main] cron 4000 check_file_access: flags 1, ret -1net helpmsg 6

net helpmsg 6
The handle is invalid.

I will get to it but if you have an idea let me know.

4) Finally I noticed that perl doesn't run with the cygwin0.dll I built in cvs (last nite).
Not sure if you see that too.

Pierre
