you mean libgcc_s.so.1 and libstdc++?

scanned /bin and /usr/bin and few programs do link it - all are C++ 
written.

None IMHO are needed in closed-source system really,

anyway (i don't have clang installed now) what clang compiled C++ programs 
use as libstdc++ ?

do clang provide it?

cannot you just use this (or other) nonGPL library?
