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 [-Wdeprecated-declarations]
The following patch adds dg-warning for it.
Tested on x86_64-linux -m32/-m64 with GXX_TESTSUITE_STDS=98,11,14,17,20,2b ,
committed to trunk as obvious.
