Ok, almost half a year later I upgrade to the latest Cygwin on a W2K
machine and get the same problem!

One simple fix [at least for NTFS partitions] seems to be the setting of
the $CYGWIN variable, e.g. in my .bashrc file:

export CYGWIN=ntea      # Fix tar permission problem!

This also has a beneficial effect on "chmode".

The User Guide warns about doing this on a non-NTFS system though!
