            Bug ID: 114773
           Summary: Raw string literals are not supported in C89 mode
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rl.alt.accnt at gmail dot com
  Target Milestone: ---

I’m currently working on supporting raw string literals in C in Clang like GCC
does, and we noticed that GCC doesn’t support them in `-std=gnu89` mode, only
in `-std=gnu99` mode and later (https://godbolt.org/z/hahja6Y87). 

Is this intentional or a bug?
