Well, Visual C++ 2012 supports some of the features, and there is always the Visual Studio 2013 if you're keen enough (which even has a few C++14 features, according to the MSDN blog.)
I also have version 4.7.2 of the MinGW GCC, which is amost there, from:
MinGW - Minimalist GNU for Windows
http://sourceforge.net/projects/mingw/
GCC proper went C++11 feature complete at version 4.8.1 and, according to
http://gcc.gnu.org/, the C++11 Language Features that only made it by 4.8.x are:
- Rvalue references for *this
- decltype and call expressions
- Generalized attributes
- Alignment support
- Inheriting constructors
- Bidirectional Fences
- Memory model
- Abandoning a process and at_quick_exit
- Thread-local storage
plus whatever library features.
But I also had to apply a patch to get the string algorithms to work. See:
Problems with std::stoi, not working on MinGW GCC 4.7.2

There is also the MinWG-build project, which has released a build of 4.8.1, but I have not tried it:
