Mounted how (i.e. with what command or feature)?
Btw, this function is only interested in directories; do directories
also return a zero for inode in that case?
Anyway, I'd consider this a bug in `stat' implemented in w32.c, and
wouldn't bother the Lisp code with that. The probability of 2
directories having _all_ of their attributes identical is very small,
even if we don't fix this in w32.c. As an additional precaution, we
could compare their absolute file names as well.
