Cygwin, Rsync and 8-bit chars (SJIS)

After reading up some more about Cygwin's libs, I think the
double-backslashes that are appearing are causing cygwin to think the path
is a DOS path, not a posix-style one.

The reason the backslashes are there is because SJIS uses them as the second
character in the encoding of some of its double-byte characters, I can't
change that unfortunately.

If this is the case then I could really do with some secret CYGWIN flag
(couldn't find it in the user guide) that can disable the DOS path parsing
temporarily, by using [env CYGWIN=nodospaths tty ntsec rsync "blah"]  for

Anybody got a clue as to what to do here?  It seems as if Cygwin might be
broken when it comes to SJIS filenames because of this, maybe the "is this a
DOS path" check could be more stringent?  If the path has forward slashes,
even one, maybe it can be left untouched?
