I posted about this several months ago.

The idea is for some severely limited embedded systems to leave out libstdc++ 
and rely only on libsupc++. On some other systems with multiple C++ compilers, 
it's possible to share libsupc++ and keep separate higher-level 
implementations.

But to be honest, you're right: you won't be able to go very far with Qt in 
the future without STL.

Here are the sizes of the several libstdc++ I've found on my system 
(technically, filesystem block size to make it easier for me):
