We could do that indeed; or, IIRC, there is a configure option
to force the use of C instead of C++. I don't mind requiring
the user to force it; it's a good reminder (and ties in nicely
with another comment below).

:-). I know it sounds self-serving, but I think we should be giving
users a one-release grace period. Make C++ the default, but with
C support for those who can't build with C++. That way, they can
still build, but they are clearly on notice about the impending
change. Then, as soon as the release branch is cut, we can flip
the switch. That way, I don't think you'll have to keep the compat
mode for much longer than you were planning to.

Definitely a possibility. Let's discuss that separately at some point!
