 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=15558&action=view)
Simple fix

I'm not 100% sure it's correct way to fix this problem but at least I can
compile the library with it.

Actually I'm pretty much sure it's incorrect way to fix gnu-versioned-namespace
as it leaves a lot of namespaces (like __gnu_pbds or std::__debug) unversioned
but I'm not libstdc++ expert...
