    The g++.dg/warn/Wstrict-aliasing-bogus-union-2.C test is also affected:
    PASS: g++.dg/warn/Wstrict-aliasing-bogus-union-2.C  -std=gnu++2b  (test for bogus messages, line 12)
    FAIL: g++.dg/warn/Wstrict-aliasing-bogus-union-2.C  -std=gnu++2b (test for excess errors)
    Excess errors:
    .../gcc/testsuite/g++.dg/warn/Wstrict-aliasing-bogus-union-2.C:8:8: warning: 'template<long unsigned int _Len, long unsigned int _Align> struct std::aligned_storage' is deprecated [-
    
    The following patch adds dg-warning for it.
