getting C-Scheme running on HP workstations

[Arthur Newman <amn@LOCUS.UCLA.EDU>]

By just installing the student version we would get the following bug:
trying to set! an undefined variable would cause a bus error and kick
you out of Scheme back to the system prompt.
I recompiled Scheme using the normal.bin file, and eval'ed
(enable-language-features).  Now trying to set! undefined variables
just gives an error message.
Are there any reasons why we had trouble with set! in the student system
that you can think of?
Thanks for any help,
Arthur Newman
