ar 'unable to rename... Invalid cross-device link'

[Matthew Woehlke]

...anyone have any guesses why rename() can't rename files in the same 
directory, if the directory is an NFS mount? This causes 'ar' to fail 
with the error:

ar: unable to rename 'libcloudobj.a' reason: Invalid cross-device link

I see this in strace with both 'ar' and 'mv':

    46  371094 [main] ar 2588 rename: -1 = rename 
(h:\<...path...>\src\objects\stWBl4pj, 
h:\<...path...>\src\objects\libcloudobj.a)

This seems to happen when the file already exists, but rename() only 
fails on NFS mounts (not local drives). Is this a problem with 'ar', or 
Cygwin's rename()?
