Re: -fnew-abi and C++? (was C++ and 2.95.1)

	If you use the -fnew-abi option of G++, you need to BUILD libgcc
and libstdc++ with that option.  -fnew-abi is not a runtime option that
you can select arbitrarily and co-exist with the old ABI.  The new ABI
affects mangling of C++ symbols.  This is why -fnew-abi is waiting for a
lot of functionality before it is enabled, because it will break
compatibility with old object files and libraries.
