By default Cygwin tries to emulate POSIX file permissions:

You can disable this by modifying your /etc/fstab file and adding the
appropriate options to cause the target locations for your files to have
the necessary options:

Specifically, you may need to modify the settings for the cygdrive
mountpoint:
