The other main problem after that is that the C++ ABI has been
changing, so having only one version of the library would cause
trouble.  But maybe that is not as big a problem now as it was in the
past?  OTOH, surely there will be some changes to the library in the
future, so it seems that it would be a good idea to be able to have
multiple versions of libstdc++.dll.a installed simultaneously?  Or is
this not possible for some reason?
