That's exactly what I meant - perhaps I was not too clear. The orignal
C-code above lets anybody to execute mount as a suid-program, which is
equivalent to set mount suid.

My set of programs mount /dev/fd0c always on /floppy/disk to avoid
such problems. They also set privileges of /dev/fd0* and
/dev/rfd0* to prevent creation of devices using editors after the
mount.
