17# There is some non-correspondance. __has_feature(cxx_user_literals) is
18# false for AppleClang 4.0 and 4.1, although it is reported as
19# supported in the reference link for Clang 3.1.  The compiler does not pass
20# the CompileFeatures/cxx_user_literals.cpp test.
21# cxx_attributes is listed as not supported until Clang 3.3. It works without
22# warning with AppleClang 5.0, but issues a gcc-compat warning for
23# AppleClang 4.0-4.2.
24# cxx_alignof and cxx_alignas tests work for early AppleClang versions, though
25# they are listed as supported for Clang 3.3 and later.
