We don't know what causes this problem which appears on some cygwin
installations and not on others, see

  http://www.unidata.ucar.edu/glimpse/netcdf/4199

but it is apparently harmless.  If you want to finish with "make
test", you can first copy libsrc/test.nc to libsrc/test_nc.sav and
then invoke "make test" to make sure all the other tests pass.  I'd be
interested in getting a copy of your test.nc file; maybe it would help
us to diagnose the cause of this problem.  I have added a description
of the problem to

  http://www.unidata.ucar.edu/packages/netcdf/known_problems.html#cygwin

Thanks for reporting the problem.
