This patch corrects the following: - Provides the required run-time support for images created by the DIGITAL C++ V6.0 and above compiler. Contact the DIGITAL C++ compiler group (cxx@lego.zko.dec.com) for details. - An updated libcxx.so which provides the required run-time support for images created by DIGITAL C++ V6.0 and above. Customers who are using Digital C++ V6.0 can use the un-documented compiler switch: -use_system_libcxx which will cause the compiler to use the system libcxx.so file when linking. DIGITAL C++ V6.0 customers should only use this switch if the resulting images are to be executed either on other systems witch have had the libcxx.so patch installed, or on Digital UNIX V4.0D and above systems.
