I'm not sure, but have two suggestions to try:

  1.  Add -DgFortran to your CPPFLAGS and run configure again
  2.  If that doesn't work, try our current netcdf-fortran test release at

       http://svn.unidata.ucar.edu/repos/netcdf-fortran/trunk/

which uses the standard F03 C-interoperability mechanisms to call C functions
from Fortran, so doesn't need the underbar or double-underbar name mangling
stuff currently in cfortran.h that only works for certain C and Fortran compiler
combinations.  If you try approach 2, you'll have to run

  autoreconf -i

first to generate a configure script, which may entail installing the autoconf
package, if you don't already have it.

If one of these works, please let us know.
