I don't know, why you pointed that out. It's of no use to feed a path
like $HOME/something to a pure win32 binary.
(Certainly, this hint is kind of important for the ubuntu version of the
script, but not for the cygwin issue, which is solely because he's
mixing cygwin and win32 and expects it work without any complication)
