There is still no minimally preproducible example here; just a (pardon me
here) rambling description of a hasty system upgrade.
It is _somewhat common_ to have to recompile C++ shared objects when compiler
major versions change.
So I am unsure if we have actually demonstrated a bug here.
Don't we need "-std=c++98" for GCC 6 in Makevars anyway, even if it's
just to save users from using C++11 constructs and then wondering why
their packages fail on CRAN/winbuilder? In my case it also saves me from
recompiling "all of CRAN" (at least for now); that's a nice side effect,
but the first part also looks important to me.
