Which ones for instance?  I have checked a couple of symbols of your 
3.4.11 list and found them all also in my system (4.6 based) libstdc++.  
I've also checked some history of config/abi/pre/gnu.ver, and the only 
meddling with 3.4.11 symbols after version 3.4.12 was added (at r147137) 
is r157067 in 2010, that tightened some exports for numeric_limits:: .


Ciao,
