Lots of warning messages.  You might see if there's a compiler option to
disable them.

I'm not sure what the problem is. We've tested the netCDF Fortran
interface on numerous systems with 4-byte reals and never seen this
problem.  I suspect that the problem has more to do with a bug in the
code designed to test the netCDF Fortran API than with the code of the
Fortran API, itself.

I suggest that you go ahead and install the netCDF package.  I strongly
suggest, however, that you test the package yourself.  You can do this
by invoking the "ncdump" utility on some netCDF files that contain real
values.  See if the output makes sense.  If it does, then the package is
probably OK and the problem probably lies with the testing code.
