`cp' never did.  Only the Windows copy commands do.

If they have the same timestamps, why do you get "source is newer"
messages?  I don't get them on my machine, and lread.c explicitly
checks for .elc time _less_ than the .el time, not _less_or_equal_.
Could you please look closer at this problem and tell where do the
messages come from, and why?

Thanks, but I don't want to rely on a GNU `cp' without checking.  And
I'd like us to understand the problem (which doesn't seem to happen to
me) better before we consider solutions.

In any case, thank you for your report.

Does this happen in the released Emacs 22.1?

What modifications are those?  Is it possible that they cause the
messages?
