[slime-devel] Lispworks and HOMEDRIVE / HOMEPATH

[Luke Crook]

I had wondered why in Windows Lispworks creates the .slime directory in a 
different location to sbcl.

Turns out that Lispworks determines user-homedir-pathname from the HOMEDRIVE and 
HOMEPATH environmental variables. I discovered this after SWANK errored out when 
Lispworks attempted to create the .slime directory on a network mapped drive.

Setting the HOMEDRIVE and HOMEPATH environmental variables in slime-lisp-
implementations fixed this.
