FWIW, my stance is not that we can't do this, just that it (like requiring
a modern compiler) has a cost that we should consider carefully before we
impose it on folks.

When we updated the compilers, we aimed for ones that would be installed on
the new LTS ubuntu release at the time of the next release.
