--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
GCC 7.0 still complains about %m with -Wformat and -Wpedantic:

$ (set -x && cat b.c && for o in '' '-Wpedantic'; do gcc -S -Wformat $o b.c;
done)
+ cat b.c
#include <syslog.h>

void f (void)
{
  syslog (0, "%m");
}

+ for o in ''\'''\''' ''\''-Wpedantic'\'''
+ /build/gcc-svn/gcc/xgcc -B /build/gcc-svn/gcc -S -Wformat b.c
+ for o in ''\'''\''' ''\''-Wpedantic'\'''
+ /build/gcc-svn/gcc/xgcc -B /build/gcc-svn/gcc -S -Wformat -Wpedantic b.c
b.c: In function ‘f’:
b.c:5:16: warning: ISO C does not support the ‘%m’ gnu_printf format
[-Wformat=]
   syslog (0, "%m");
