the rest of the dimension queries. Correct error in library where types used
in sub-group variables but that were added to the file after the sub-group was
created weren't available for sub-group variables to use. Start cleaning up
test suite and un-commenting tests that were commented out (got up to
nc_test4/tst_fills2.c, alphabetically) before running into an error in HDF5.
range_error checks in netCDF-4 type conversion code. Made netCDF
attribute tests with type conversion more comprehensive and stringent,
fixing bugs identified with better tests. Changed a test in
nc_test/tst_atts.c to use netCDF-3 file instead of netCDF-4 file,
because that directory is supposed to be for tests that work with
--disable-netcdf-4. Added test demonstrating NCF-171 bug on 32-bit
platforms, only run when configured with --enable-extra-tests.
