Just an FYI, there's a proposal to add a -Wbitfield-conversion flag that does
something slightly different than the behavior described in this issue; for
reference, see: https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00723.html
I'd be fine with it doing either the behavior in that patch, or the behavior
from this issue...
