Note from Niels:

This was not part of Almy's XLISP package, I got this unixstuff.c off of 
comp.lang.lisp.x:

I got sick of the control keys not working in the unix-frontend
for xlisp.  To date, the best unix-front end has been the one
provided by Niels Mayer in his winterp distribution, for instance
the SYSTEM function worked.  However, those control keys still did
not work, and I sure like to use CTRL-c when I get dumped into
a break loop!  What we have here is a hacked version of Niels Mayer
unix-front end, I got this working on a Sun SPARC station (BSD
derivative), the hooks are there for S5 also.  Job control still
works in BSD, another common control key is CTRL-t, which
shows garbage collection information.  I have also
included some timing functions that break the time down into
CPU and REAL time that a function or program takes.

Enjoy !!
