I've used the / as /cygdrive since the beginning of /cygdrive.  The
issue you see is the fact that Cygwin doesn't require a physical
directory to mount as Linux and friends do.  If you want to see them
then you simply create a physical empty directory in the Cygwin root
directory.  I do find it interesting that the mount also changes the
output of `ls /proc/cygdrive/` but that is a different issue.

Another method to see which drive letters are available is to simply
type mount at the command prompt.
