--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
This is because we call warning instead of warning_at. All other warnings in
warn_for_sign_compare are already warning_at. The fix is easy & safe, but
technically it's not a regression, so not sure if it can go into trunk now.
Maybe it can as a "docfix".
