Hi Carlie,

We too have run into problems building the netCDF using the MIPS 7.4
compilers on IRIX.

We tested the following combination of options with "make test" in the
"libsrc/" subdirectory (this is the simplest "blunder" test):

    Compiler Options            "make test"
    ---------------------------+------------
    -g -n32                     fails
    -g                          fails
    -O -n32                     succeeds
    -n32                        fails
    -g -o32                     succeeds

So, you can use the '-O -n32' and '-g -o32' flags for both CFLAGS
and FFLAGS and be successful.

Note that this is definitely a compiler problem, not an netCDF one :-)
