commit r14-4069-gf1b06f571dfe4c854cd57482ca87d5ca9f0d570d
Author: Jonathan Wakely <jwakely@redhat.com>

    libstdc++: Remove dg-options "-std=gnu++20" from 27_io tests
    
    The testsuite will automatically select C++20 for these tests now, and
    removing the hardcoded -std option allows them to be tested for C++23
    and C++26 as well.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/27_io/basic_istream/extractors_character/char/lwg2499.cc:
