--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Forwards compatible is not guaranteed; only backwards compatible.
That is you can compile with X and run with (X+1) libraries but not the
opposite way around. This is true with almost all software including but not
limited to GLIBC, GCC, libstdc++ (and even Windows).
