Subject: B20: 'find' modifies file access dates

Problem: 'find' changes the access dates of files it checks to the day of
its execution. It should access only directories it traverses. This happens
only with directories containing sub-directories. The files it touches are
the first in disk order. The first file not touched always appears after a
sub-directory entry.

Configuration: Beta 20 under Win98, FAT & FAT32 file systems, find version
4.1

Example: cd <some directory with sub-directories>; find; ls -luU
You will see that most of the files (first ones) have an access date of
today.

This doesn't happen when I use Linux 'find' on the same file systems, so the
problem probably isn't in 'find' itself; This also doesn't happen when I use
Windows' 'Find Files' on the same file systems, so the problem probably
isn't with the WIN32 API; So I guess the problem is with the cygwin DLL.

Please respond directly to me, since I'm not on this list (yet).

I'll appreciate any help.
