3.3.2. The GNU C++ Standard Library
The libstdc++ package contains the GNU C++ Standard Library, which is an ongoing project to implement the ISO 14882 Standard C++ library.
Installing the libstdc++ package will provide just enough to satisfy link dependencies (i.e. only shared library files). To make full use of all available libraries and header files for C++ development, you must install libstdc++-devel as well. The libstdc++-devel package also contains a GNU-specific implementation of the Standard Template Library (STL).
As the C++ language and runtime implementation has remained stable throughout Red Hat Enterprise Linuxes 4, 5, and 6, no compatibility libraries are needed for libstdc++. However, combatability libraries compat-libstdc++-296 for Red Hat Enterprise Linux 2.1 and compat-libstdc++-33 for Red Hat Enterprise Linux 3 are provided for support.
3.3.2.1. GNU C++ Standard Library Updates
The Red Hat Enterprise Linux 6 version of the GNU C++ Standard Library features the following improvements over its Red Hat Enterprise Linux 5 version:
Added support for elements of ISO C++ TR1, namely:
<tr1/array>
<tr1/complex>
<tr1/memory>
<tr1/functional>
<tr1/random>
<tr1/regex>
<tr1/tuple>
<tr1/type_traits>
<tr1/unordered_map>
<tr1/unordered_set>
<tr1/utility>
<tr1/cmath>
Added support for elements of the upcoming ISO C++ standard, C++0x. These elements include:
<array>
<chrono>
<condition_variable>
<forward_list>
<functional>
<initalizer_list>
<mutex>
<random,
<ratio>
<regex>
<system_error>
<thread>
<tuple>
