Hi,

Did you upgrade from 1.5 to 1.7.5 or did you go through some 1.7.X?

This problem may be due to the way the groups are computed in Cygwin 1.7
but there must be something special about your install, otherwise we would
see more reports. It's significant that you are on a non-US system.

Actually there was a change in Feb 2010
http://cygwin.com/ml/cygwin-cvs/2010-q1/msg00109.html
to fix a bug on non-US systems. But this may have caused a bug in your
older Windows 2000 ...

Could you
- compile and run the attached program
- in a shell, type
         cacls 'c:\WINDOWS\system32\user32.dll'    (or where ever 
user32 is on your system)
         cacls 'c:\WINDOWS\system32'
and send me the outputs ?

Thanks

Pierre
