[netCDF #XNG-578851]: nf_strerror reference when compiling WRF

Looking at the first instance.
> mpif90  -w -ffree-form -ffree-line-length-none -fconvert=big-endian 
>       -frecord-marker=4     -c  -I/usr/include -I../ioapi_share diffwrf.f
It looks like the -I path is missing to where the netcdf fortran header
should be located (presumably /sci/wrf/gcc/include).
Since you set them in configure.wrf, I do not understand why they
do not appear in the mpif90 line above. In fact, the list at line 201
appears to specify a large number of -I flags that do not appear
in the mpif90 command above. Any idea why?
