This is probably a really dumb question... but why does wine support
UNIX paths? What is the circumstance where a Windows application will
be trying to access a native file or directory? The only example I can
think of is that an app has specifically been written to be used in
Wine, in which case, shouldn't native UNIX paths be disabled by
default, and perhaps turned on with an environment variable?
