-/* Perform a tri-state query on whether STAT_BUF_1 and STAT_BUF_2

-   -1 for indeterminate (the latter is generally possible only on
-   mingw).  Algorithms that use this macro must be prepared to handle
-   the indeterminate case without wrong results.  For example, if an

-   distinct, use SAME_INODE()==1; whereas for an optimization that is
