hoek,
Why do you think this WITH clause is special?
I've taken the liberty of formatting the code, and can't see what's wrong. (Maybe I'm just too tired)
I believe 9i did have subquery factoring.
with users_with_dba_privs
       as (    select distinct child user_name
                 from (    select null parent, 'DBA' child from dual
                       union all
                       select granted_role parent, grantee child
                         from dba_role_privs)
                where child in (    select username from dba_users)
           start with parent is null
           connect by parent = prior child)
    select 'select_any_table', substr(sys_connect_by_path(c, '->'), 3, 512) path, c
      from (select null p, name c
              from system_privilege_map
             where name = 'SELECT ANY TABLE'
            union all
            select -- users/roles and roles granted
                  granted_role p, grantee c
              from dba_role_privs
             where granted_role != 'DBA'
            union all
            select -- users/roles with select any table
