           Product: gcc
           Version: 11.2.1
            Status: UNCONFIRMED

Excess errors:
/home/seurer/gcc/git/gcc-11/gcc/testsuite/g++.dg/cpp0x/decltype-bitfield1.C:13:17:
warning: width of 'A::l' exceeds its type

This appears to be a 32-bit only issue in gcc 11.  It works fine on trunk.
