Sorry, I'm talking about the regular -version-info option.

Agreed.  I think the only option is for libstdc++ to get it's act together
and finally define and implement a stable ABI.  Vendor compilers have been
doing this for years, so it's certainly feasible, and spending effort to
achieve this goal is much better than implementing further kludges around
the underlying problem.
