I thought I'd throw in a suggestion for my problem with getting open to
return EISDIR. It seems that the win32 call CreateFile doesn't
distinguish between an access error and an error because you were
trying to open a directory as a file. Please take this with a grain of
salt since I'm a total cygwin.dll newbie (haven't compiled cygwin yet...)
so this may be totally way off base.
