Well, I thought SetCurrentDirectory didn't work like that,
but if it does then there is no reason why that implementation
couldn't be used. GetCurrentDrive ought to verify that second 
character is indeed ':' (preparing for UNC names) but that should 
work, too. Using wide character versions would be preferred, though.

So, I guess those routines should work. Perhaps I should rewrite my
patch in order to make use of this kind of routines instead of exporting
stuff from ntdll.

Ok, I've had time to check this on win98 and SetCurrentDirectory doesn't
work like this.  This is doable as its done in wcmd:
G:\wine\programs\wcmd>c:
C:>cd windows
C:\windows>g:
G:\wine\programs\wcmd>c:
C:\windows>
