I have a bit of trouble with generic statemens like this.

Maybe it helps if we compile a list of actual ABI breakage points and
attribute them properly? Like the switch in string handling in gcc's
libstdc++ on NetBSD (and I already forgot when this happened - from
netbsd-8 to netbsd-9?) But this should not matter for any other
compiler's libstdc++ nor for gcc on any other platform.
