How can I know if my compiler support XXXX C++11 feature? [duplicate]

How do I check for C++11 support?

I am writing a small library and I would like to use class enums whenever the compiler supports them. I also want to use other C++11 features, such as final and override keywords.

So far, I have used tricks to make sure it compiled on all versions of GCC, but I when I booted my Windows partition, Visual Studio 2010 started complaining too. Here is an example of the tricks I used:

#if __GNUC__ == 4 && (__GNUC_MINOR__ > 7 || \
      (__GNUC_MINOR__ == 7 && __GNUC_PATCHLEVEL__ > 1))
#   define TATO_OVERRIDE override
#   define TATO_NO_THROW nothrow
#else
#   define TATO_OVERRIDE
#   define TATO_NO_THROW throw()
#endif

I know that the newest version of Visual Studio already supports a batch of new features too. What I would like to have, is something like a set of macro which tells me what features are available on the compiler I am using.

#ifdef THIS_COMPILER_SUPPORTS_CLASS_ENUMS
  ...
#endif

Does this exist? Is there a library that does that?

The compiler’s documentation?

Let me clarify. I know how to find those information, my problem is elsewhere. I don’t want to go through every possible compiler’s documentation to gather those information, especially since the same compiler might support different features with respect to its version. This is what I have been doing so far, and what I am looking for is actually a way not to do that.

Boost actually has a wide range of such macros available. You could use that. Otherwise, the only way is to essentially check the compiler's version and use your knowledge of the features supported in that version to decide if a feature is available or not.

Essentially, what Boost does, except manually.
