22ca1336dc MFC r261283: 
Import libc++ 3.4 release.  This contains a lot of bugfixes, and some
preliminary support for C++1y.

MFC r261604:

HEAD is not buildable for the past day.  Commit a 'quick fix' in order to permit
buildworld to complete.

Reviewed by:	theraven

MFC r261608:

Apply a cleaner solution for the sign warnings that can occur when
compiling libc++'s <locale> header with -Wsystem-headers on.

This has also been submitted upstream.

Reported by:	asomers

MFC r261801:

An ABI incompatibility crept into the libc++ 3.4 import in r261283.  It
was caused by upstream libc++ commit r194536, which aimed to make the
headers more standards-compliant, by making std::pair's copy constructor
trivial.  Unfortunately, this could cause certain C++ applications using
shared libraries built against the previous version of libc++ to crash.

Fix the ABI incompatibility by making std::pair's copy constructor
non-trivial again.

Please note: Any C++ applications or shared libraries built with libc++
between r261283 and this revision should be recompiled.

8b9f5e4153 Add a c++/v1/tr1 include directory containing symlinks to all of the standard 
headrs.

Lots of third-party code expects to find C++03 headers under tr1 because that's
where GNU decided to hide them.  This should fix ports that expect them there.

792f34fe5e After r253839, which modifies ld's behaviour to not automatically pull 
in needed libraries, change libc++.so into a linker script, so it can
automatically pull in libcxxrt.so.

abfbe8a705 Fix broken macro checking in the libc++ Makefile, introduced in r241909. 
This caused -std=c++0x not to be passed to the build by default.

aef46581d9 Allow building libc++ with any custom -std=xxx flag. Note that using 
-std=gnu++98 will give a lot of warnings with clang, so please use
-std=c++0x or higher, or use NO_WERROR.

9e6c8f62e0 Add libcxxrt's objects (prefixing them with cxxrt_ to avoid collisions) 
to libc++.a and libc++_p.a, to make static linking of C++ executables
with libc++ easier.  This is similar to the approach used in libstdc++.

4176aa17ae Install libcxxrt's C++ ABI and unwind headers. This is done in libc++'s 
Makefile, so these headers go into the same destination directory as
libc++'s own headers, currently /usr/include/c++/v1.

7af7d69c50 Make sure libgcc_s is finished building in _startup_libs before 
building libcxxrt with high -j levels.  The workaround in
libc++/Makefile isn't necessary once that race is solved.

7bd22d0949 Import new versions of libcxxrt and libc++. 
Please tests any C++ code you care about with -stdlib=libc++!

ad5598305f 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...
