I don't follow.   There are certainly multiple ABI issues, and what I am
saying is that we have to be careful, unless we can prove that there are
not and will not be issues.   The C++ ABI is not guaranteed stable.
There is also the NetBSD libstdc++ change.   And there are other compilers.

Right, so therefore we must build *everything* with the same compiler.

I thought you were arguing that this was unnecessary.
