[ACT-R-announce] CMUCL support for the ACT-R Environment

[db30@andrew.cmu.edu]

Thanks to the efforts of Ethan Glasser-Camp at RPI, the ACT-R
Environment now contains the necessary support to run with
CMUCL.

The first test version is out on our site now on the software
page, so feel free to give it a try.  You can also get it directly
at <http://act-r.psy.cmu.edu/software/Environment-unix.zip>.

It hasn't been run through a lot of tests yet, but as far as I can
tell it does run.

However, there are 2 minor issues with it.  First, the stepper
window may be a little slow to respond because there's a call
to sleep in the loop on the Lisp side waiting for the responses.
It's there to avoid a situation where the processor gets swamped
in a polling loop.  There's probably a better way to handle that,
but I don't know what that would be.  The other issue is that
CMUCL reports a lot of warnings as the environment runs about
lambda functions that have unused parameters.   What I need to do
is fix the lambda definitions so that those parameters are ignored,
but for now if you know of the switch to turn off those
warnings let me know because that's the quick and dirty fix.

If you try it and encounter any problems please let me know.
