Linda,
Note that 'mv' and 'cp' share code (copy.c) that does the actual
move/copy. That file does have the message you refer to above,
conditional on errno==EINVAL after rename(). Apparently, Cygwin's (or,
rather, newlib's) rename doesn't have that behavior. That's where I'd
start tracking it down.
