Applications must use 64 bit off_t. E.g. by defining
#define _LARGEFILE_SOURCE
#define _FILE_OFFSET_BITS 64
or take special precautions to interface with the libraries by 64 bit integers
where the .h files prescribe off_t. Not to use 64 bit file i/o will keep the
application from producing and processing ISO images of more than 2 GB size.

XXX we should enforce 64-bitness for off_t
