There's 
<https://developers.redhat.com/products/developertoolset/overview/> 
(also available for CentOS 6), which brings newer compiler versions and 
bundles the "extra" parts of libstdc++ statically.  Works fine when you 
build a complete executable at least; I myself never needed the case 
where you just ship a single library to be consumed by others, though, 
so don't know about that part.
