Here is the updated long double ABI patch on top of current 4.3 branch.
Regtested on ppc-linux, ok for 4.3?
2008-02-29 Jakub Jelinek <jakub@redhat.com>
* config/abi/pre/gnu.ver: Remove
_ZNKSt3tr14hashIgEclEg@@GLIBCXX_3.4.10 and
_ZNKSt4hashIgEclEg@@GLIBCXX_3.4.10 export.
* config/os/gnu-linux/ldbl-extra.ver: Export
_ZNKSt3tr14hashIgEclEg@@GLIBCXX_LDBL_3.4.10
and _ZNKSt4hashIgEclEg@@GLIBCXX_LDBL_3.4.10.
* src/hash.cc: Only define long double hash specialization if
_GLIBCXX_LONG_DOUBLE_COMPAT_IMPL is defined.
* src/compatibility-ldbl.cc: Include "hash.cc".
(_GLIBCXX_LONG_DOUBLE_COMPAT_IMPL): Define.
(_ZNKSt4hashIeEclEe): New alias.
* testsuite/util/testsuite_abi.cc (check_version): Support
GLIBCXX_LDBL_3.4.10.
