Changes in "lib/dirfd.c" this year are from commit 3f0950f65ab
(2023-04-27 01:42:25 +0200).
The compiler reports:
CC lib/libgnu_a-dirfd.o
../lib/dirfd.c: In function 'rpl_dirfd':
../lib/dirfd.c:83:13: warning: unused parameter 'dir_p'
[-Wunused-parameter]
83 | dirfd (DIR *dir_p)
| ~~~~~^~~~~
CC lib/libgnu_a-dirname-lgpl.o
From the code, I can't see how the paremeter can not get used while
the code is traversed.
