std::shared_ptr is new to c++11, so you probably have to turn on
c++11 with g++. (Actually only sort of new; as you know, shared_ptr
had been in namespace tr1.)
===== test.cpp =====
#include <memory>
std::shared_ptr<int> p;
===== test.cpp =====
The compile command "g++ -std=c++11 -c test.cpp" works, but
"g++ -c test.cpp" fails with the error:
test.cpp:2:1: error: 'shared_ptr' in namespace 'std' does not name a type
std::shared_ptr<int> p;
^
My version of g++ is
g++ --version
g++ (rubenvb-4.8-stdthread) 4.8.1 20130324 (prerelease)

Yes, mingw-w64 is able to compile this code, but you have to
tell it explicitly to use c++11; is doesn't by default.
(You can also use "-std=gnu++11" if you want both c++11 and
some of the gniu extensions.)

Happy C++11 Hacking!
