svn commit: r314104 - head/lib/libcxxrt

[Dimitry Andric]

Author: dim
Date: Wed Feb 22 18:44:57 2017
New Revision: 314104
URL: https://svnweb.freebsd.org/changeset/base/314104

Log:
  Surround any unmangled C++ names in libcxxrt's version map with 'extern
  "C++"', otherwise ld refuses to make the symbols global in the final
  library.  This causes the __int128-related symbols to go missing when
  the library is stripped during installation.
  
  Helpful hints:	emaste
  MFC after:	2 weeks
  X-MFC-With:	r314061
