--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Would be related to:

gcc -c -DHAVE_CONFIG_H -g -O2  -I.
-I/home/marxin/Programming/gcc/libiberty/../include  -W -Wall -Wwrite-strings
-Wc++-compat -Wstrict-prototypes -Wshadow=local -pedantic  -D_GNU_SOURCE
/home/marxin/Programming/gcc/libiberty/pex-unix.c -o pex-unix.o
/home/marxin/Programming/gcc/libiberty/pex-unix.c: In function
‘pex_unix_exec_child’:
/home/marxin/Programming/gcc/libiberty/pex-unix.c:659:6: warning: declaration
of ‘err’ shadows a parameter [-Wshadow=local]
  int err = errno;
      ^~~
/home/marxin/Programming/gcc/libiberty/pex-unix.c:569:47: note: shadowed
declaration is here
        int toclose, const char **errmsg, int *err)
                                          ~~~~~^~~

I'm going to fix it.
