@SVN rev 241903 on 2012-10-22 18:25:04Z by dim

Import libc++ trunk r165949.  Among other improvements and bug fixes,
this has many visibility problems fixed, which should help with
compiling certain ports that exercise C++11 mode (i.e. Firefox).

Also, belatedly add the LICENSE.TXT and accompanying CREDITS.TXT files,
which are referred to in all the source files.

@SVN rev 235798 on 2012-05-22 18:30:14Z by theraven

Merged libcxxrt and libc++.  Now available for testing on 9-stable with
-stdlib=libc++.  Changes to libstdc++ not yet merged, so it is not yet possible
to mix libstdc++ and libc++ in the same program.

Merged revisions: 226702,226785,227006,227755,227983,227987,228531,228630,228761,229067,230127,232950,233098,234715-234716,234772

@SVN rev 227983 on 2011-11-25 20:59:04Z by theraven

Import libc++ / libcxxrt into base.  Not build by default yet (use
MK_LIBCPLUSPLUS=yes to enable).  This is a work-in-progress.  It works for
me, but is not guaranteed to work for anyone else and may eat your dog.

To build C++ using libc++, add -stdlib=libc++ to your CXX and LD flags.

Bug reports welcome, bug fixes even more welcome...
