They are still supported (and we're committed to supporting that version
2 Fortran API for the foreseeable future).  Some possibilities why
you don't see them include:

  - They were installed in a separate Fortran library, libnetcdff.a (note
    the "ff"), so to link an application requires -lnetcdf -lnetcdff
  - The 4.1.3 library was built with that API disabled, which is not the
    default, but requires one of the configure options --disable-v2,
    --disable-f77, --disable-fortran, or --enable-c-only.
  - The configure script was unable to find a Fortran compiler that worked
    for Fortran-77 or was unable to link objects created by the C compiler
    with the Fortran compiler it found.

Looking at the output from running "nc-config --all" or the output of the 
configure script from when the 4.1.3 library was built may clarify what's 
going on.
