It works - ST 72 is up and running again.
Thanks a lot Dan. :)

I've attached the complete changeset (ALLDEFS and sf2 files from 
http://wuarchive.wustl.edu/languages/smalltalk/Smalltalk/Squeak/goodies/Smal
ltalk-72/
is required). Note that Dans patch to Scanner breaks parsing of alternate
syntax 
(which allows prefix colons on keywords). 

Bye
