Howdy Mark!

Thanks for checking this!

There are various small issues that have come out in the HDF5 beta release
(some because of bug *you* reported ;-). These are being worked out by the HDF5
team, and meanwhile more tests have been added to netCDF-4 to be more ticklish
to bugs in this area.

If you get the current netCDF-4 snapshot and build it, you will see that this
test is now skipped. The HDF5 programmer is working on this now. Get the
snapshot at:
http://www.unidata.ucar.edu/software/netcdf/builds/snapshot/index_4.html

If you provide the --enable-extra-tests option to configure you will see this
test again, and it will fail. When future versions of HDF5-1.8.0 come along
which fix this bug, this test will be moved back with the rest, and out of the
"extra-tests" category.

Thanks again!

Ed
