simonb d61cb0817b Don't use <err.h>. Use ANSI prototypes (no dependance on the __P()
macro).  Add new fwrite_be_offt() function which writes out a big-endian
64bit number regards of the size of off_t on the host machine.

Also fix ``bug'' in previous - even though the off_t pointers were
stored big-endian, the individual card lenghs were in host-order.  The
cards.pck files are now identical when make on a big- or little-endian
machine.

Now builds a correct cards.pck file on non-NetBSD machines as well
- tested on Ultrix and Solaris (but Solaris needs -lsocket to get
htonl()).
