Richard Smith531c9a02013-03-10 00:11:00[diff] [blame]45<p>By default, Clang builds C++ code according to the C++98 standard, with many
46C++11 features accepted as extensions. You can use Clang in C++11 mode with the
47<code>-std=c++11</code> option. Clang's C++11 mode can be used
48with <a href="http://libcxx.llvm.org/">libc++</a> or with gcc's libstdc++, but
49patches are needed to make <a href="libstdc++4.4-clang0x.patch">libstdc++-4.4</a>
