I forgot:

MIT Kerberos, HP-UX Kerberos, Solaris Kerberos, AIX Kerberos and
our own ABI uses the gss_OID_set definition from rfc2744 
(or the cbind-00 draft).

In the /usr/include/xom.h header file on HP-UX 11.31 I no longer see
any OID_set definition, and the /usr/include/gssapi/gssapi.h header
file contains the rfc2744 variant with "size_t count".
