Maybe it's trivially fixable, but I don't even want to look at it,
since we've talked about updating the minimum gcc version so long.

Unless somebody cares, and comes with a trivial fix to make old
compilers happy, let's just do that.

We had some other reasons to just say gcc-4.6 is the minimum version anyway.
