Try:

mount("/dev/hdc","/mnt","iso9660",MS_MGC_VAL | MS_RDONLY,NULL);

Don't know if that's your problem, but the mount manpage
says you need the magic number if you want the RW flags
to be honored. It could be that the mount syscall is
attempting to mount the filesystem read/write in the
absence of a valid RW flag (though the manpage is unclear
about the default behavior).
