cp --preserve=mode not right on rh4 and nfs

[Warren L Dodge]

I have built coreutils-6.12 on a GNU/Linux RedHat3 system. When I use
the "cp" command with the --preserve=mode,timestamps switch there is a
problem where a copy to a nfs mounted file system does not set the
timesamp properly.

I show examples below where I run the command on GNU/Linux RedHat3 and it
works as expected. Then I run the same binary on GNU/Linux RedHat4 and
it does not work properly.

I believe I reported this quite some time ago. I was hoping the problem
was solved in coreutils-6.12 as some of the users are needing this
functionality. 

The /tmp on my machine is the local drive. The installed_tree/bin is
where I am executing the command. The installed_tree is a nfs mounted
file system. It is served by a NetApp system.
