This directory contains the headers and prebuilt binaries for the GNU libstdc++-v3 C++ Standard Template Library implementation. These are generated from the toolchain sources by the rebuild-all-prebuilt.sh script under build/tools. To use it, define APP_STL to 'gnustl_static' in your Application.mk. See docs/CPLUSPLUS-SUPPORT.html for more details. This implementation fully supports C++ exceptions and RTTI.
