The above warning results from the linker finding the routine
NF90_STRERROR_in_NETCDF in both netcdf.o and ../libsrc/libnetcdf.a.
This warning (and similar ones) may be safely ignored.

These error messages apparently result from problems with the
test program netcdf_test.f90, rather than from problems with
the library. Russ Rew, who knows more about this 8-byte integer
problem than I, has a good explanation (and workaround) at
<http://www.unidata.ucar.edu/glimpse/netcdf/4454>.

The important thing is for the Fortran-90 interface that you built
to handle all the primitive types that you'll use.  If it does, then you
should be OK to do the "make install".
