You have to keep the old shared libgcc around somewhere.
Libc soname bumps are extremely rare, as you have to recompile
*everything*. I wouldn't worry about it too much.

It'd be simpler and more reliable to take the damn C++ code out of
libgcc and put it in libstdc++ where it should have been since day
Yes, I know the argument about not requiring people to use libstdc++,
and I don't buy it. C, Fortran, Java, Chill, Ada, etc. all insist you
use the language runtime library. Why should C++ be different?
