This should be fine in either MIT krb5 and Heimdal.  In MIT krb5 it's
equivalent to calling error_message(krberr) (a com_err function).  In
Heimdal it's a little more complicated.

Of course, you won't get an extended error message this way, only a
simple translation of the number to an error table string.
