'tac' trying to use "/tmp"; Error: not found

*REF: 'tac' trying to use "/tmp"; Error: not found*
*_______________________________________________________*
*|  'tac'  utility dies with a not found "/tmp" error.  |*
*¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*
  I didn't see this problem in older 'tac' versions...

  I created "/tmp" under my root directory:
*    "c:\tmp"* (Windows 10), *to no avail*.

  I make a  *tmp*  dir directly *above*, in the *parent's 'tac' dir*:
     *"../tmp"*, at the same level as other usual folders like:
        *bin*, *dev*, *etc*, *lib*, *sbin*...,
  and now: *'**tac' works fine**!*

  I think that in *line 70 of "tac.c"*:




*ID: tac (GNU coreutils) 9.0    Packaged by Cygwin (9.0-1)    Copyright (C)

...if it is defined as:

*#define DEFAULT_TMPDIR "**..**/tmp"*

*instead of* the *actual*:

*#define DEFAULT_TMPDIR   "/tmp"*

it could work fine!
