That is really nice and as I said in my first posting, you can blame me
now for incomplete testing. It seems to me, that VC7.1 is an open
question, but that is part of the other posting of you.

Thanks for the correction.

All initial answers implied to me, that the corresponding definitions
where not provided by boost, so I just was fighting for them ;-)
Just forget that b..dozer.

I will do that, thanks Dave.
