Several years later... the linux binaries have gone stiff, we have no statically-compiled imptoc binary or bootstrapping x86 compiler,
and the imptoc here still had some bugs that were caused by the code not matching the compiled grammar - and no copy of the grammar
used to build the grammar tables.  Well, now at least we have a working grammar (imptocps) reconstituted by examining all the ERCC
Imp grammars we could find and rebuilding tables using a translated version of newps. So at least we have a starting grammar that
we can now modify to fix imptoc ... once we can compile imptoc again.

If updating these files to my net server, put them in /home/gtoal/history.dcs.ed.ac.uk/archive/languages/imp80-tmp/imptoc
(where apart from newps.c and imptocps, the files date back to 2008)
