I recently conducted a quick-and-dirty survey of C++11 (formerly known as C++0x) features available on various platforms and compilers that I had lying around. My testing was not authoritative nor rigorous. (For example, g++ without -std=c++0x actually compiles lambdas without throwing an error, so I marked it as supported even though it does give a stern warning.) I'm posting the results here, mostly for my own future reference.

Other, probably more thorough information about C++11 feature support:
- C++0xCompilerSupport (Apache's C++ Standard Library Wiki)
- Summary of C++11 Feature Availability in gcc and MSVC (Scott Meyers)
- C++0x Core Language Features In VC10: The Table (Microsoft)
My quick-and-dirty test suite is available for download.
