OK.

Though this makes me wonder how far back I am expected to support.  I
think all of my current machines are Ubuntu 16.04 or newer, which
means gcc-5.4 or newer.  If I need to support older gcc versions, I
may need to install older OS verions, or at least have them available
as a chroot.  Looks like Ubuntu 14.04 is gcc-4.8 and Ubuntu 12.04 is
gcc-4.6, so I'd need something from circa 2012 to find these kinds of
problems myself.
