Re: [netcdfgroup] How to enable has-f90 in NetCDF-F?

I'm building NetCDF-F 4.4.2 with the Intel, GNU and PGI compilers, and am seeing this configuration setting 

      --has-f90   -> no

when I run

    nf-config --all

    What does the config.log tell you?
I don't see the stringhas-f90 appear anywhere in theconfig.log or the regular build output. 
Digging around some more, I see these lines in theconfigure script:

   5283 # Set the default fortran builds; default is to build f03
   5284 *nc_build_f90=no*
   5285 *nc_build_f03=yes*
               ......
   5543 # Guarantee build state; f90 currently overrides f03
   5544 if test "x$nc_build_f90" = xyes ; then
   5545   nc_build_f03=no
   5546 else
   5547   nc_build_f03=yes
   5548 fi
Does this mean that NetCDF can be compiled with the F2003 interfaces or the F77 interfaces but not both? 
Here's what's in the include directory:
*netcdf4_f03.mod* *netcdf_f03.mod* netcdf.mod netcdf_nf_data.mod 
   netcdf4_nc_interfaces.mod  netcdf_fortv2_c_interfaces.mod
   netcdf_nc_data.mod        netcdf_nf_interfaces.mod
netcdf4_nf_interfaces.mod netcdf.inc netcdf_nc_interfaces.mod typesizes.mod 

and I'd expect that it could have generated*_f90.mod files as well.
Thenf-config output doesn't suggest that this is an either-or:

   *  --has-f90   -> no**
   **  --has-f03   -> yes*

      --has-nc2   -> yes
      --has-nc4   -> yes
Looking at the configure output, here are some lines that look relevant to the Fortran (I'm using GCC 5.1.0 here):
