--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Have you done a clean build?
Those symbols were added last week, but if you are doing an incremental build
in an existing build tree you need to do 'make clean' in the libstdc++-v3 build
directory and then build again.
If you're using the subversion trunk you need to be prepared to do such things.
