--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The code here is correct.  In that the warning might be valid for normal code
but the comparasion it is making is valid one.
Mainly because we do:
              /* Restore backslash followed by newline.  */
              BUF_APPEND (base, cur - base);
              base = cur;
              BUF_APPEND ("\\", 1);
