--- Comment #6 from Franz Sirl <sirl at gcc dot gnu.org> --- I see. If you really close it as WONTFIX, could this small deficiency at least be documented in the manual? I guess the non-warning case happens only when the switch-statement directly (no other statements in between) precedes the case-statement?
