[netCDF #XVY-916374]: problem with sequential NF_OPEN in netcdf-4

["Unidata netCDF Support" <support-netcdf@xxxxxxxxxxxxxxxx>]

> Hi,

> The problem arises when using a sequential NF_OPEN in a parallel
> application (code is attached below). If only one process calls NF_OPEN
> then the program simply waits and it seems that it hits a mpi barrier.
> If all process call NF_OPEN (which is not desired here) then the program
> continues without complaining. However, if the file does not exist it
> complains with "Error initializing for parallel access". In contrast,
> NF_CREATE just works fine. Can it be that NF_OPEN and NF_OPEN_PAR got
> slightly mixed up?

Howdy Ingo!

I have just fixed this in the netCDF code base. Can you build the daily
snapshot and see if it works for you:

Thanks!
