I'm busy with other things at the moment and can't get to it right away. 
 If it's easy for you to suggest a patch, why don't you go ahead, and 
Robert can test it.  Or you can wait a couple weeks until I can look at it.

BTW, file-notification=gfile works fine in the Cygwin-w32 build, so I'm 
not sure there's any need to put a lot of effort into this.
