Hi,

the function slime-file-name-merge-source-root from slime.el does not work on windows, because it adds a slash in front of the device in a pathname. That causes emacs to call ange-ftp to a nonexistant machine. The attached patch solves the problem by checking whether the original path started with s slash and only then inserts a slash again in front of the buffer root.

Hope this is useful
