The current status is that I redesigned the HDS file format to cope with
64-bit addressing and I have the C routines which interface to this format.
It then got bound with an effort to develop a "pure C" HDS - with BOTH 32
and 64-bit FORTRAN wrapper layer.
No-one seemed very enthusiastic about me finishing or releasing this (until
now!) - but I need to get back to it I see!
It would be be quicker (and safer) to use the new file format, back out the
"pure C" HDS changes and keep the existing FORTRAN top-level (with INTEGER*8
where appropriate) as a first step.
