Win32 port: expand-file-name uses backslashes? (Emacs compatibility)

I was hit by the fact that expand-file-name does not work the same way as in Emacs. It returns the result in backslash format in win32 and forward slashes in Unix. This is a bit hard and ugly when I combine paths always with forward slashes. (expand that) + "path/here" \that\dir/path/here It also defeated In my code member and pushnew tests now when everything was not in forward slash format. Oh well... In Emacs it always returns forward slashes which I think is easy for a develooper. Would it be possible to modify it so that expand-file-name had an additional argument FORMAT that would control the path expansion. By default it would return always forward slashes to regain Emacs compatibility. With extra argument: FORMAT 'native as OS default.
