Features: Don't record for AppleClang Features are currently recorded accidentally for all versions of AppleClang > 3.4 (I have no idea how that relates to upstream Clang). Presumably that version has the features which are accidentally recorded, but in the future features will be recorded initially for only AppleClang >= 5.1, which would appear as a feature regression. Commit v3.1.0-rc1~635^2~11 (Don't load Clang-CXX from AppleClang-CXX., 2013-11-11) ajusted the logic for the CXX language. Make a similar change for the C language. 2014-11-12 22:20:36 +00:00			`include(Compiler/Clang)`
