Problem with completer-file on Windows

Hi!

The function completer-file in completer.el starts with these lines:

  ;; Canonicalize slashes under windows-nt for proper completion
  (when (eq system-type 'windows-nt)
    (setq string (replace-in-string string "/" "\\\\")))

Unfortunately, the Emacs that I'm using (21.2, prebuilt binaries, full
version, on Windows XP pro) doesn't know the function
replace-in-string and thus barfs.

I fixed this for me

  ;; Canonicalize slashes under windows-nt for proper completion
  (when (eq system-type 'windows-nt)
    (setq string (replace-regexp-in-string "/" "\\\\" string)))

but it don't have other Emacsen on Windows around to test whether
it'll work there.

However, I can confirm that on the Linux and FreeBSD machines I have
access to replace-regexp-in-string is known on 21.2 but not on
20.7. None of them knows replace-in-string. (I assume the existence or
non-existence of these functions doesn't depend on the underlying OS.)

I'm using the ilisp-20020702.tar.gz snapshot.

Cheers,
Edi.
