Well, that is going to break a lot of things.  If MacOS is one of them,
I won't shed a tear.  OTOH, do we expect MacOS X on Intel to run any
_existing_ LSB-first applications (i.e. built for other platforms)?  If
not, then we could simply define the file format for MacOS-X to always use
MSB-first byte order, and the library would need to know to use the usual
network byte-order-conversion operations when reading and writing ticket
files.

Of course, as Sam points out, if MIT has never supported krb4 file caches 
on OSX, then this becomes a moot issue.
