	* mk_priv.c (krb_mk_priv): Fix up call to pcbc_encrypt().  By
 	taking the address of key, the 5th arg to pcbc_encrypt() was
 	actually a (char **) cast to a (C_Block *).  The reason for this
 	is that a C_Block (actually a des_cblock) is typedef'ed from a
 	char[8], which by being in the parameters of the definition of
 	krb_mk_priv() becomes of type (char *).  This means that using the
 	address operator on key resulted in a pointer to a pointer to a
 	char rather than a pointer to a des_cblock, which would have been
 	innocuous in this case because pcbc_encrypt() actually takes a
	(des_cblock *) as the 5th (ivec) argument.  The moral is to never
 	pass around naked arrays as function arguments; instead, pass
 	around pointers to arrays to avoid spontaneous conversions to
 	pointers sneaking up.  Note that CNS actually uses a (C_Block *)
	everywhere, and maybe we should as well.  *whew*
