Chris,

You were too fast :-)  I uploaded a second version about a day later fixing
this.  These troubles were caused by the DCG translator using is_list/1.
Cleaning this up, I made some mistakes generating wrong code on awkward
DCG code.  Best thing to do is to get boot/init.pl from the CVS server, 
overwrite it in the installation and run

	pl -O -o boot32.prc -b boot/init.pl

(adjust to your particular installation).

	Cheers --- Jan
