Does anybody know if there's a difference with aCC on HPUX 11 (we're talking
about version 10.20 here). Because when checking out the status pages for
HPUX 11 they don't seem so bad.

Is there currently an option in boost to use the old include files, I did'nt
see any. So would it be interesting to add the new headers that include the
old headers in boost/compatibility ?

But since there's no iostream but only iostream.h I suppose namespace std
does'nt even exist ?
(sorry can't check myself now since I only have a few days a week acces to an
HPUX machine)

Seems (from cvs log) that John Maddock, Jens and Aleksey have worked on
hp_acc.hpp so I hope they can provide some insight here. As I said before I'm
trying to help you (John Hagen) out but have little experience with aCC.

You definitly should avoid to do that !!!!!

(John, I would like to continue the discussion on the boost-ml since there
are some people with experience with boost on HPUX that will be able to
provide some more info, I'm not crosposting to jamboost since all jamboosters
are also boosters)
