Yes, sorry about that, the "-lsz" should not have been included in LIBS
if the HDF5 library was not built with szlib, and that's not needed for
netCDF-4.

You could try including "-fPIC" in CFLAGS before running configure when
compiling HDF4.  Alternatively, building HDF4 as a shared library may work.

Sorry we don't have a definitive answer for this.  Currently our test build
with HDF4 is not working on our snapshot release, although I believe it was
working with 4.2.1.1.

Of course another solution would be to build without --enable-hdf4, but I'm
assuming you have a need for the limited HDF4 reading capabilities in the
netCDF-4 C libraries.
