[slime-devel] emacs-nt+slime+cygwin+clisp: how to set the DISPLAY variable?

I am running emacs +slime (2008-09-28) on windows and clisp on cygwin.

I would like to use gnuplot.  If I call gnuplot from clisp which comes
with cygwin, it opens a gnuplot window.

But not if I call it from slime. gnuplot states : unable to open
display ''.  Looking at environment variables that Emacs gets and
passes to subprocesses, there is no DISPLAY variable.  So it seems
that gnuplot did not get a value of DISPLAY.

I guess I could create a windows variable DISPLAY so that emacs
inherits it and passes it to its subprocesses (and clisp).  But is
there a way to do that from within slime?

Thank you,
