Hi,

I experienced a  bizarre problem, originating in that a file
created under Cygwin B20.1 is given the admin group as owner if
my user account is part of the administrator group (NT4.0, SP4).

I looked through the email archives and found an explanation to
the phenomenon (below).

Are there any plans on some additional functionality in the CygWin
libraries that I can make use of to overcome this problem?

Meanwhile, I guess inserting
	chgrp(filename,geteuid(),getegid());
everywhere a file is created will have to do...

Thanks,

/Olle


From http://www.cygnus.com/ml/gnu-win32/1998-Sep/0162.html :

This is a win32-ism. When a user who is a member of the BUILT-IN
Administrators group creates a file, ownership of the file is set to the
BUILT-IN Administrators group. The Win32 API layer is doing this, not the NT
kernel and not NTFS.
