<pre>Standing Document 6 recommends a series of macros for checking the status of
various standard features in the implementation. While clang seems to have
implemented this for pure language features, libc++ does not yet have support
for this. For example, although libc++ does support compile-time integer
sequences as specified in n3658, the <utility> header does not define
__cpp_lib_integer_sequence as recommended by SD6.</pre>
