It's something for the user to decide, I think.  For example, I'm
guessing that GetCurrentDirectory returns a file name with backslashes
and might have some weird letter-case conversions applied to it; users
might not want that.

Do you know of some Windows application that uses PWD in an
incompatible fashion?  I use Windows for quite some time, and have
never seen such a beast.  The only applications that use PWD are
ported Unix and GNU tools, and they all use it in a consistent manner.
