This patch looks fine.

Will v3 be the default in gcc 3.0?  That is what matters, I think.

Will package builders put libsupc++ into the -dev packages or into the
ordinary runtime packages?  That might be a disadvantage.

I think we should follow what C++ does and link it into our library.
That seems safest.
