I guess clang is re-using system headers which belong to older gcc 4.2
I also have gcc48 installed, how can I make clang to refer gcc48 headers?

There two C++ runtime libraries, the old gcc libstdc++ which is used by
default and the new C++11 libc++. You can use the latter like this:
clang++ -std=c++11 -stdlib=libc++ -otest test.cc
