Well, gnulib does support this "fundamentally deficient" system.
Personally, I think that a utility macro such as SAME_INODE should
uphold its contract on all supported systems.  But that's me; I'm not
a gnulib maintainer, so feel free to ignore me.

In any case, as I already wrote, the change I suggested in SAME_INODE
is only a bonus: if no one cares about the code in Grep's main.c that
I think belongs to SAME_INODE, then no change is necessary, because
the code works as it is.

How is the problem with st_ino on Windows different from what
SAME_REGULAR_FILE in src/system.h is trying to do to cope with all
kinds of very similar breakage in `struct stat' on Posix hosts?
