No need. 'normpath' will automatically convert the forward-slash into a 
backward-slash on Win32 platforms.

More generally: My defacto solution to the problem of path manipulation 
is that the "path algebra" operators are strings, rather than object 
methods or functions. When you join two paths, all of the instructions 
as to how to combine the two paths are contained in the string.
