The way to indicate compiler options for building netCDF is in
environment variables, not by changing files.  See the discussion of
this in the netCDF Installation Guide:

  
http://www.unidata.ucar.edu/packages/netcdf/docs/netcdf-install/Specifying-the-Environment-for-Building.html

So, for example, you could run the configure script like this to set
the environment variables FFLAGS and F90FLAGS:

  env \
    FFLAGS="-qsuffix=f=3f" \
    F90FLAGS="-qsuffix=f=f90" \
    ./configure  --prefix=/path/to/installdir

I don't think the above value of FFLAGS is needed, but the F90FLAGS
probably is.  I just tried these environment variables on an AIX 5.1
system:

  env \
    CC=/usr/vac/bin/xlc \
    FC=/usr/bin/xlf \
    F90='' \
    CXX=/usr/vacpp/bin/xlC \
    ./configure

and it built, tested, and installed the C and Fortran-77 interface OK.
I'm having problems getting the options right for our xlf90 compiler
right now, so maybe someone else can help with that.
