Just FYI I was the enterprising soul who translated the code from Fortran
to C.  I still have at least some of the intermediate files.  Happy to
answer any questions.

That said, most of the work was manually rewriting the f2c output into
something more C like.  For me this wasn't an exercise in translation
between languages, it was an exercise in making a version of Zork more
available.  So I probably don't have anything useful to add that is
relevant to the compilers list.

In particular I changed the format of the data file.  I wrote a translation
program between the old format, a new format, and a text format.  The text
format let me make minor changes to things like the leaflet text.
