[Bug c++/30332] [4.1/4.2?/4.3? regression] bit-field: optimization BUG?

In any case, I consider this a bug in gcc. The problem doesn't happen with
gcc 3.3 or 3.4 or 4.0, so it's a regression.

That said, there's a second problem: before 4.1.x, we warned:
g/x> /home/bangerth/bin/gcc-4.0.x/bin/c++ x.cc -O2
x.cc: In function 'int main()':
x.cc:13: warning: converting negative value '-0x000000001' to 'long long
unsigned int'

This doesn't happen any more, not even with -W -Wall

W.
