Comment (by kencu):

 This is a bit interesting, actually. On 10.6.8, where we currently use
 libc++ from llvm 5.0, libcxx has capability far beyond what was installed
 on MacOSX 10.7.

 Apple has not enabled any testing for the libc++ version installed;
 instead, it assumes that certain OS versions have certain versions of
 libc++. This is mostly true, of course.

 However, if we ever do start upgrading libc++ on these older 10.7 to 10.12
 systems, which we could do, then we would want to disable tis system
 version testing.

 There is a simple toggle to disable in in a clang header called
 {{{_config}}}, and I have disable that OS version testing on my older
 systems to not artificially limit them when the libc++ version often has
 all these capabilities.
