Use snprintf instead of mempcpy plus itoa_word and remove unused definitions. There is no potential for infinite recursion because snprintf only use strerror_r for the %m specifier. Checked on x86-64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, and s390x-linux-gnu. Tested-by: Carlos O'Donell <carlos@redhat.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com>
