Well, I don't know what we're really talking about here... but it sounds like you're trying to determine a compiler's features based on its version number.  That's inherently pretty fragile, don't you agree?

I do know that the clang folks discourage trying to determine clang's abilities from its version number.  Instead, they have a mechanism called 'Feature Checking Macros' described here:
