errcode_t and krb5_error_code are both intended to hold com_err codes,
which are 32-bit values.  A profile plugin module could return a larger
value, but it would be incorrect to do so.

The type "long" was chosen for errcode_t at a time when there were
platforms with 16-bit ints to worry about, and there were no C99
fixed-width types to take advantage of.
