Unfortunately, it's not that simple.  Actually, the file "bin/scsh" is
a sh-script that runs the scsh virtual machine with a certain heap
image.  To make the vm allocate more heap add the command line
argument "-h num" where num is the heap size in number of words to
that line.  For 32 MB heap, the Makefile line looks like this:

echo 'exec $$lib/$(VM) -h 8388608 -i $$lib/$(IMAGE) "$$@"' \

However, if you want to run Commander S with more heap, you have to
modify its install.scm.  The variable IMAGE-HEADER contains the exec
call for the scshvm, just add "-h num" there:

(define image-header 
  (format #f "#!~a/scsh/scshvm -h 8388608\\\n-o ~a/scsh/scshvm -i\n" 
          (lib-dir) (lib-dir)))

I think adding a command line option to the commander-s binary to
specify the heap size is a good idea.  I'll try to do that.

Which warning?  The warning about undefined variables or the warning
concerning the heap size?
