I am unable to reproduce this on F16,
GNU ld version 2.21.53.0.1-6.fc16 20110716
Copyright 2011 Free Software Foundation, Inc.
Can you give me some more information about your ld, and include any special
flags used to get the warnings. Thanks.

you need to use ld-gold for gcc build and configure gcc with
--enable-symvers=gnu.
the problem is in the libstdc++-v3/config/abi/pre/gnu.ver:
grep shows duplicated lines:
gnu.ver: _ZNKSs11_M_disjunctEPKc;
gnu.ver: _ZNKSbIwSt11char_traitsIwESaIwEE11_M_disjunctEPKw;
gnu.ver: _ZNKSs11_M_disjunctEPKc;
gnu.ver: _ZNKSbIwSt11char_traitsIwESaIwEE11_M_disjunctEPKw;
full build log attached.

Fixed:
/mnt/share/bin/H-x86_64-binutils.20120220-gold/bin/ld: warning: wildcard match
appears in both version 'GLIBCXX_3.4' and 'CXXABI_1.3' in script

With patch.
The rest:
/mnt/share/bin/H-x86_64-binutils.20120220-gold/bin/ld: warning: using
'GLIBCXX_3.4' as version for
'_ZNKSt15basic_stringbufIwSt11char_traitsIwESaIwEE3strEv' which is also named

are correct warnings, but the symbols are correct. This is symbol hiding, and
gold warns for this but GNU ld does not. Doesn't matter, binary is still the
same.
