  I'am putting something together which gets us started. What I really
  want to do is fix the proplem P^2 reported in the NeXus Java binding.
  My proposed Makefiles are NOT incomaptible with autoconf. It makes
  autoconf's job even easier as most of its job is done when it gets the
  top level make_general right.

   Two points here:
   - The Fortran API things are so small, it does not really warrant an
     own library.
   - I want to make things easier for the Fortran programmers, just one
     library to link against in addition to HDF.
   Yet another option is to link the napif.o file plus the NeXus library
   and not to build a library.
