    This regressed the test for C++20 and higher:
    FAIL: g++.dg/strub-internal-pr112938.C  -std=gnu++20 (test for excess 
errors)
    FAIL: g++.dg/strub-internal-pr112938.C  -std=gnu++23 (test for excess 
errors)
    FAIL: g++.dg/strub-internal-pr112938.C  -std=gnu++26 (test for excess 
errors)
    
    Here is a fix.

            * g++.dg/strub-internal-pr112938.C: Add dg-warning for c++20.
