Thanks very much for doing these tests and reporting the results
(recently followed up on the poplog-dev email list).
Development on The Poplog Common Lisp system essentially stopped
seven or eight years ago. Before that it had merely been
made consistent with most of CLTL rather than ANSI common lisp.
The status is summarised here:
http://www.cs.bham.ac.uk/research/poplog/doc/lisphelp/bugs
http://www.cs.bham.ac.uk/research/poplog/doc/lisphelp/lispnews
A few years after the work on Poplog Common Lisp ended, Poplog
became available as an open source free system (when SPSS bought
ISL www.isl.co.uk), but most of the development work since then has
concerned pop-11 the core language.
So it would be great if some Lisp experts were to take it in hand and
bring it up to ANSI common lisp standard, insofar as that is compatible
with the implementation using the Poplog virtual machine (no
interpreter, only an incremental compiler, etc.).
However I don't know whether there is a real need for a free open source
common lisp, as I am not really a user of lisp. (I would be if I did not
have Pop11 !!)
If anyone wishes to work on it I and others interested in the
development of poplog would be willing to help, and of course when the
port to OSX is complete there would be more beneficiaries.
The same applies to anyone who wishes to work on bringing poplog
Prolog or Poplog ML up to date.
Steve Leach's comments on Paul's message identifying possible remedial
steps were sent only to the poplog-dev email list. But they could
be made available to anyone wishing to take this further.
