I've actually done a reghunt, which revealed that those symbols (in
src/c++98/locale-inst.o, src/c++98/wlocale-inst.o) were introduced by
this patch:

2011-07-18  Martin Jambor  <mjambor@suse.cz>

        * ipa-prop.h: Include alloc-pool.h, all sorts of updates to general
        comments.
        (ipcp_values_pool): Declare.
        (ipcp_sources_pool): Likewise.

I.e. there are *no* libstdc++ or C++ changes involved at all.  IMO this
is a bug, plain and simple.
