I have a fiarly hideous proposal for a way to write out krb4 ticket files 
on 64-bit platforms so that they will be parseable both by tools that 
believe issue_date is 32 bits and those that believe it is 64 bits.  I also 
have corresponding code for reading it back in.

The downside is that my technique works only on little-endian platforms.

I'll post more details later; at the moment I'm off to dinner.
