Try the following:

1) Run "mount -m | sed 's^C:/^F:/^' > /copy_mounts.bat" on your computer
   (computer A)
2) Run the resulting copy_mounts.bat on the remote computer (computer B)

Voila.  Your remote machine should now think it's Cygwin's / is in
"F:\unix".

P.S. The above assumes that you have your Cygwin / on computer A in
"C:\unix", and that computer A's C:\ disk is mounted on computer B as F:\
