double backslash problem in elisp

[Xah Lee]

this is really a strang error.

eval this:
(replace-regexp-in-string "/" "\\" "//169.254.153.147/xah/Documents/
alice artwork scans/")


i get this error:

Debugger entered--Lisp error: (error "Invalid use of `\\' in
replacement text")
  replace-match("\\" nil nil "/" nil)
  replace-regexp-in-string("/" "\\" "//169.254.153.147/xah/Documents/
alice artwork scans/")
  eval((replace-regexp-in-string "/" "\\" "//169.254.153.147/xah/
Documents/alice artwork scans/"))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp nil nil)


any idea why?

double backslash should mean single backslash as far as i knows...

basically am trying to prepare a path to feed to w32-shell-execute.
