In CLISP the following works (note the single backslash):
(parse-namestring "g:\path")
the following does not (note the double backslash):
(parse-namestring "g:\\path")
=> PARSE-NAMESTRING: syntax error in filename "g:\\path" at position 2

I somewhat fail to debug slime, since edebug in emacs has trouble 
tracing the swank functions. Though it seems the problem lies with the 
two backslashes.
