This command returns w/o problems.

Dito.

Here we have the problem. For "/cygdrive/c", stat returns strange values
for the %u and %g fields (uid and gid): 4294967295. In your Emacs
stanza, I suspect this is out of integer range, which is guaranteed only
for -2**29 to 2**29 - 1 (-536870912 to 536870911).
One possible fix could be the following patch (line numbers might vary):

Another possibility would be to switch to the "smb" method, which is the
natural choice when accessing MS Windows machines. But this would
require a local installation of the Samba client on your Mac; don't know
whether this is possible.
