@option<-Wstrict-overflow=1> invoke.texi contains: @table @option @item -Wstrict-overflow=1 ... -- Summary: gcc manpage contains "@option<-Wstrict-overflow=1>" Product: gcc Version: 4.3.0 Status: UNCONFIRMED Keywords: documentation Severity: normal Priority: P3 Component: middle-end AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: burnus at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33321
