No, please don't use DOS_NT: it is defined in the MS-DOS port as well, 
where `stat' does return a unique inode for a directory.

You cannot do that for directories, because GetFileInformationByHandle 
needs a handle, and Windows doesn't let you open a directory and get a 
file handle for it.

I disagree.  I think it's very important that the Windows port tries to 
return more-or-less meaningful inode numbers, so that we don't have to 
devise a special kludge for each Emacs primitive that needs an inode.
