* forward.c: Remove unused #include <krb5/crc-32.h>.

* forward.c:  Remove unused #include <krb5/crc-32.h>.
* kerberos5.c (kerberos5_send):  Remove code for sending a checksum
of a zero-byte string; we can just send no checksum at all.  This
eliminates dependency on <krb5/crc-32.h>.
(kerberos5_forward):  Remove extra parameter to krb5_get_for_creds,
probably accidentally inserted during context changes -- which don't
seem to be here in the ChangeLog.
* kerberos.c:  Remove prototypes for krb4 functions, since
some of them are wrong with CNS (u_long vs. KRB_INT32 conflicts).

These changes BUILD but have not been RUN yet.  But at least they build.
My apologies.		-- John
