I need to fix Authen::Krb5 (a Perl wrapper) not rely on this krb5
internals.  Obviously, this is going to stay a krb5 wrapper, and won't
switch to GSSAPI.  So I'd really appreciate if someone would fix the
appl/simple/client/sim_client.c example not to rely on <k5-int.h>, so
that I can apply the parallel changes to the Perl port of this example
code.

The alternative would be to delete all this code from Authen::Krb5.
(The wrappers for non-public krb5 functions have to go either way.)

Thanks,
Florian
