            Bug ID: 107954
           Summary: Support -std=3Dc23/gnu23 as aliases of -std=3Dc2x/gnu2x
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

  Target Milestone: ---

Hi,

I raise this ticket (I agree not very important, and more a feature request
than a bug) following a similar one on C++/clang side and a remark from Aar=
on
Ballman:
https://github.com/llvm/llvm-project/issues/59300#issuecomment-1335623903

It seems that the future C2x standard has reached at least the feature free=
ze
phase and the expectations are that it will be ratified in 2023. So, it is
already the time to accept -std=3Dc23/gnu23 as aliases of -std=3Dc2x/gnu2x =
or is it
early for this ? On C++ side gcc already accepts -std=3Dc++23 since gcc 11 =
as now
C++ standards seems to strictly follow the 3 years cadence.

Cheers,
Romain=
