slime setup on Win10

xI'm a retired "old guy", and a hobbyist code monkey. :)  I've
decided to revisit Clisp/emacs/slime/quicklisp for something to do.

Got most everything working on my Win10 laptop, except that when I
do a M-x slime in emacs, slime chokes at the very end on a bloody
windoze short directory name to a TEMP file. This warning occurs
while running the swank.fasl file.  Any way to edit that sucker so
that I can give it a "full" filename?  Thanks!
