If you need to run with a small heap (or even if you don't)
you probably want to use the startup flag -g0, to turn on the
mark-and-sweep GC code. Or modify SLIB.C to have that be the
default.
Obviously being able to GC during a computation is very helpful
in avoiding heap overflow.

The reason I didn't make g0 the default on systems that could use it
was that I didn't want to take up a lot of source-code size in
a bunch of architectural specific "#ifdef" conditionalizations.
(Usually what makes a C program "portable" just look at GNU EMACS,
which has probably been ported to more machines than any other C
program that exists. It is a thicket of conditionalizations in places).
Not that that is a bad thing, it just makes the code difficult to
read.
