           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

          Assignee: unassigned at gcc dot gnu.org
          Reporter: richard-gccbugzilla at metafoo dot co.uk

GCC's documentation of GNU C extensions appears not to mention allowing raw
string literals in C, which GCC has permitted in -std=gnu* since GCC 5.
