Comment (by Jigsaw52):

 The rule with the cast fixes #25440 on systems affected by it. The #25440
 fix replaced the old version of the rule (without the cast) with the cast
 version. However, we now discovered that, on toralf system (which was not
 affected by #25440), removing the old rule breaks tor.

 In attempt to identify why toralf system behaves different than mine
 (which was affected by #25440), I asked toralf run a small program to
 check check the value of AT_FDCWD and size of several relevant types but
 all the results were equal to my system. As I was unable to find a way to
 identify which systems need which rule, my solution was to enable both
 rules.

 I have added the changes file and improved the commit message.
