That should be fixed.  AFAIK, libstdc++ and libg++ enable vtable hack
on all linux systems, because of a libio compatibility problem.  If
this is the case, we must make sure the compiler gets vtable
definition right, otherwise the part of the C++ library that is built
into libgcc.a will be link-incompatible with the part that gets built
into libstdc++.  This is just plain wrong!

I don't care, as I was installing a test version of gcc 2.8.1 exactly
for this purpose: testing.
