ls reports different permissions for the same file, depending on whether I provide a Windows-form path or a UNIX-form path:

$ /bin/ls -ldi c:/apps/amq-versions/amq.12.1.0-RC42/conf /cygdrive/c/apps/amq-versions/amq.12.1.0-RC42/conf
7318349394635879 drwxrwxrwx+ 1 tboemker Domain Users 0 Sep 12 07:56 /cygdrive/c/apps/amq-versions/amq.12.1.0-RC42/conf
7318349394635879 drwxr-xr-x  1 tboemker Domain Users 0 Sep 12 07:56 c:/apps/amq-versions/amq.12.1.0-RC42/conf

$ /bin/ls --version
ls (GNU coreutils) 8.15
Packaged by Cygwin (8.15-1)
...

Am I missing something, or is this a bug?

Thanks,
