Re: help with dynamic-space-size

Here's what I get back:

inferior-lisp-program is a variable defined in ‘inf-lisp.el’.

Its value is "sbcl"
Original value was "lisp"

so the answer is no, that setq is not being executed, but the value 
"sbcl" is being picked up
from somewhere.

I have looked at the file inf-lisp.el which seems formidably complex,
do I have to change something there ?
