yes. One of the major changes from 2.8 to 3.0 was the introduction of POA
support. you can tell omniidl to create skeletons for the POA, or for the
BOA. While the old _sk_XXX skeletons are BOA specific (and therefor non-
portable), the new skeletons are called POA_XXX, which is part of the CORBA
specs. I.e. using the POA you can write portable software that compiles with
any ORB. Of course, there are lots of other points about POA vs. BOA. Read
about them in "Advanced CORBA programming with C++" by Henning and Vinoski.

To generate the old skeletons, you have to use

omniidl -bcxx -WbBOA
