I am running Windows versions Emacs and CLISP.

If I have temporary-file-directory set to "~/temp", slime loading will report
;; Loaded file C:\Users\977315\documents\.slime\fasl\2013-09-29\clisp-2.49-windows-x86\swank.fas
...
*** - OPEN: Directory #P"C:\\Users\\...\\documents\\.emacs.d\\~\\temp\\" does not exist

I set temporary-file-directory to an absolute path, such as
""c:/Users/.../AppData/Local/Temp/"

slime loads OK.

I grepped slime's lisp files for temporary-file-directory, but did not see it. I tested this with
clisp -norc option.

Is this a bug - since on Windows Emacs accepts `~' for the home directory?

Thanks,

Mirko
