Comparing the additions in x86_64-linux libstdc++, I still see a couple of
wrong exports, in particular since gcc 4.5 the following symbols
_ZTIn@@CXXABI_1.3 OBJECT WEAK DEFAULT 16
_ZTIo@@CXXABI_1.3 OBJECT WEAK DEFAULT 16
_ZTIPKn@@CXXABI_1.3 OBJECT WEAK DEFAULT 32
_ZTIPKo@@CXXABI_1.3 OBJECT WEAK DEFAULT 32
_ZTIPn@@CXXABI_1.3 OBJECT WEAK DEFAULT 32
_ZTIPo@@CXXABI_1.3 OBJECT WEAK DEFAULT 32
_ZTSn@@CXXABI_1.3 OBJECT WEAK DEFAULT 2
_ZTSo@@CXXABI_1.3 OBJECT WEAK DEFAULT 2
_ZTSPKn@@CXXABI_1.3 OBJECT WEAK DEFAULT 4
_ZTSPKo@@CXXABI_1.3 OBJECT WEAK DEFAULT 4
_ZTSPn@@CXXABI_1.3 OBJECT WEAK DEFAULT 3
_ZTSPo@@CXXABI_1.3 OBJECT WEAK DEFAULT 3
were added. Those surely need to go into CXXABI_1.3.5, not CXXABI_1.3,
as they weren't exported in gcc 3.4 (nor 4.5).
Plus, I believe we aren't exporting new _ZTS* symbols for some time, only
_ZTI*, right?
I'll try to post updated abilist files for
i686/x86_64/powerpc{,64}/s390{,x}-linux once this is resolved.
So here is a patch to fix that up. Ok for trunk/4.6?

* config/abi/pre/gnu.ver (CXXABI_1.3): Don't export _ZT[IS][PK]*[no].
(CXXABI_1.3.5): Export _ZTI[PK]*[no].
