No. Nobody's going to touch libio.
But, since libio depends on C++ object layout, it will stop working
when the ABI changes. Someone (presumably the glibc/libstdc++ people)
will have to work out how to adjust libio to work with the new ABI.
You might as well see the breakage as soon as possible. :-)
