New Revision: 251066
URL: http://svnweb.freebsd.org/changeset/base/251066

Log:
  Fix warnings from newer clang versions about constexpr member functions
  not being implicitly const in libc++'s <chrono> header.  The warnings
  have been introduced because of new language rules recently adopted by
  the C++ WG.  More info:
