Well, if your patch makes sure that on a "unix" mapping (as opposed to
"win95" !) we only lookup the *exact* case sensitive name instead of
iterating through all sorts of case cases (heh ! :), then I guess
your patch is right.

I guess nobody really cared about having correct behaviour of the "unix"
mapping mode.
(since everybody should use "win95" for normal use anyway)
