A good first step would be to flip the switch from -Wno-narrowing to
-Wnarrowing in the warning flags GCC uses when building, as C++11 has
stricter rules about narrowing conversions. This would be useful even
if we don't end up going to C++11 yet, as such narrowing conversions
are bad even in versions of the standard where they're allowed.
