Yes, in the sense that we have gotten the nctest program, which tests all
the netcdf library interfaces, running successfully on the Alpha.  However
we know there may still be bugs, because nctest doesn't test everything
exhaustively.

We'll have to duplicate the problem here first.  Thanks for reporting enough
detail so that we can reproduce it.  I'm involved in an all day meeting, so
in case I don't get to it this afternoon, I'm also forwarding this to Steve
Emmerson (address@hidden) in case he has time to work on it today.

Thanks for the offer, but I don't think that will be necessary.
