In Wheezy I fare no better than in Squeeze.

The intention is to make an empty file occupying the whole
partition. Then another filesystem can be mounted on that
empty file; or "another filesystem can occupy that file" might
be better terminology. The -C option is explained briefly
by man mkdosfs. Loop device is explained in Wikipedia.
